3-MMC

Legal status: 3-MMC (3-methylmethcathinone) is controlled, reached by Singapore's class-based scheduling of cathinone NPS under the Misuse of Drugs Act (First-Schedule Class A / Fifth-Schedule NPS class), which captures cathinone derivatives.
Consequences if caught: MDA trafficking is a severe offence, but 3-MMC sits BELOW the capital tier: the Second-Schedule death-penalty thresholds are drug-specific (heroin, methamphetamine, cocaine, etc.) and cathinones/3-MMC are not on that capital list — heavy imprisonment and caning, not the mandatory death penalty.
If prescribed / medical: No recognised medical use and no lawful prescription route.
Documentation: No lawful personal-import route; zero-tolerance enforcement even though not a capital-listed drug.

7-Hydroxymitragynine (7-OH)

Legal status: 7-Hydroxymitragynine, a kratom alkaloid, is a Class A controlled drug under the Misuse of Drugs Act: it is separately named alongside mitragynine, with kratom leaf prohibited because it contains them — controlled together with the plant. It is not among the narcotics in the MDA Second Schedule capital-trafficking thresholds, so it is not death-eligible.
Consequences if caught: Class A possession, import or trafficking carries heavy imprisonment and caning; the alkaloids sit below the MDA Second Schedule capital-trafficking tier.
If prescribed / medical: No lawful medical route — kratom's alkaloids are Class A controlled drugs with no medical use in Singapore.
Documentation: No lawful personal-import route for a Class A controlled drug.

Adderall

Legal status: Adderall (mixed amphetamine salts) has no separate legal identity — it is regulated AS amphetamine: class A controlled drug under the Misuse of Drugs Act 1973 (First Schedule) — 'Amphetamine' is named.
Consequences if caught: Possession/use of a Class A drug up to 10 years or S$20,000. IMPORTANT: amphetamine is NOT in the Second-Schedule capital-trafficking list (which names methamphetamine >250 g, opiates, cocaine, cannabis), so amphetamine trafficking is NOT death-penalty-eligible — general Class-A trafficking penalties (5–20 years + caning) apply.
If prescribed / medical: Prescription stimulant via strictly controlled medical channels; carrying it without a local permit/prescription risks arrest.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

Consequences if caught: No penalty for adult consumption in permitted places/times; public drinking in the restricted window and in Liquor Control Zones (e.g. Little India) carries fines.
If prescribed / medical: n/a — a beverage, not a medicine.
Documentation: Sold at licensed outlets on proof of age; off-sales cut off at 22:30. No traveller permit but duty allowances are limited.

Amyl Nitrite

Legal status: Amyl nitrite is a prescription-only medicine in Singapore; the Health Sciences Authority classifies alkyl nitrites such as amyl nitrite as prescription medicines to be used only under medical supervision, and treats retailed alkyl-nitrite 'poppers' as unregistered/illegally supplied health products.
Consequences if caught: Unauthorised sale or supply of amyl nitrite as an unregistered prescription medicine is an HSA regulatory offence; as a medicine it is NOT a death-eligible controlled drug under the Misuse of Drugs Act — the capital narcotics regime does not reach amyl nitrite.
If prescribed / medical: Distinct from the consumer 'poppers' product: HSA treats amyl nitrite as a prescription vasodilator medicine requiring medical supervision, not a freely retailed inhalant.
Documentation: No over-the-counter or retail sale; amyl nitrite requires a prescription and HSA-regulated supply.

Ayahuasca

Legal status: Singapore treats the ayahuasca brew as a Class A controlled drug and, unusually, names the plants directly: the Central Narcotics Bureau lists Banisteriopsis caapi ('Caapi / Ayahuasca / Yage') and Psychotria viridis ('Chacruna') among plants containing the controlled substance DMT, stating that plants and their derivatives containing controlled drugs are illegal under the Misuse of Drugs Act; the preparation is thus caught exactly as DMT, with NO religious exemption.
Consequences if caught: Import, trafficking, possession or consumption of the ayahuasca brew is a Class A offence under the Misuse of Drugs Act; trafficking carries a minimum of 5 years' imprisonment and caning, with capital thresholds for large quantities.
If prescribed / medical: DMT and the ayahuasca brew have no medical or prescription status in Singapore; DMT is a prohibited Class A controlled drug.
Documentation: The CNB 'Plants that contain controlled drugs' listing expressly names ayahuasca (Banisteriopsis caapi) and chacruna (Psychotria viridis) as DMT-containing controlled plants; the tryptamine generic covering DMT was added to the First Schedule (Class A) in 2016.

Barbiturates

Legal status: Barbiturates are prescription-controlled substances (barbituric acid and its derivatives) transposing the 1971 psychotropic schedules; they sit below the Misuse of Drugs Act narcotic tier and are regulated as controlled/poison-scheduled prescription medicines.
Consequences if caught: Unauthorised possession or supply of a prescription-controlled substance draws a fine and/or imprisonment. Singapore's death penalty (MDA Second Schedule) applies only to narcotics and amphetamine-type drugs above trafficking weights — barbiturates are not death-eligible.
If prescribed / medical: Phenobarbital is dispensed as a prescription antiepileptic (a WHO Essential Medicine); the sedative-hypnotic barbiturates are tightly controlled.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.

Buprenorphine

Legal status: Buprenorphine — internationally a 1971 Schedule III opioid, a lighter tier than methadone — is a Class A controlled drug under Singapore's Misuse of Drugs Act 1973 but is absent from the capital Second Schedule; it sits below the death-eligible tier, confirmed.
Consequences if caught: Unauthorised possession or trafficking of a Class A controlled drug is heavily penalised (imprisonment and caning), but buprenorphine carries no capital trafficking threshold — the death penalty (MDA Second Schedule) reaches only named drugs such as morphine (>30 g) and diamorphine (>15 g), confirmed.
If prescribed / medical: Dispensed as a controlled medicine for opioid-substitution/analgesic use on prescription.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.

Cannabis / THC

Legal status: Controlled drug under the Misuse of Drugs Act
Consequences if caught: Trafficking: more than 500 g (cannabis resin >200 g; cannabis mixture >1,000 g) — death penalty; less than 330 g — 5–20 years' imprisonment + 5–15 strokes of the cane; 330–500 g — 20–30 years/life + 15 strokes. Possession: less than 330 g — up to 10 years or a S$20,000 fine or both. Consumption: 1–10 years + up to S$20,000 fine. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

Cathinone

Legal status: Controlled — cathinone (khat's natural principal alkaloid) is a 1971 Convention SCHEDULE I psychotropic and is a Class A controlled drug in the First Schedule of the Misuse of Drugs Act (Cap. 185). Mechanism: 1971 Sch-I transposition, named. As the parent compound it is DISTINCT from the khat PLANT (Catha edulis, which the CNB separately lists as a plant containing a controlled drug) and from the synthetic cathinones (mephedrone, added to Class A in 2010) that derive from it; cathinone is the named Class-A alkaloid, cathine the milder metabolite (1971 Schedule III). It sits BELOW the capital tier: the MDA Second Schedule mandatory-death thresholds are drug-specific (diamorphine, meth, cocaine, cannabis etc.) and do not include cathinone — no death exposure.
Consequences if caught: Class A: possession and trafficking of the alkaloid carry imprisonment and possible caning, but cathinone is not a Second-Schedule capital-quantity drug — not death-eligible.
If prescribed / medical: 1971 Schedule I / Class-A substance with no accepted medical use and no lawful prescription route for the isolated alkaloid.
Documentation: No licit personal-carry or import route for a Class A drug.

CBD

Legal status: CBD (cannabidiol) is a Class A controlled drug: 'cannabinol' and 'cannabinol derivatives' are separately listed in the First Schedule to the Misuse of Drugs Act, and the CNB treats any hemp/CBD product from Cannabis sativa as a controlled drug — zero-tolerance with no THC-free carve-out.
Consequences if caught: CBD is prosecuted as a Class A drug — consumption 1-10 years and/or a fine up to S$20,000 (urine/hair testing), with possession/import escalating by weight. The mandatory-death thresholds are plant-form specific (cannabis over 500 g, mixture over 1,000 g, resin over 200 g) with no weight listed against 'cannabinol' derivatives, so pure CBD isolate does not by itself fall in the capital band (left to confirmation), while real-world CBD oils as cannabis extracts can cross those cannabis/mixture weights.
If prescribed / medical: There is no retail or self-medication route; any cannabinoid pharmaceutical requires case-by-case HSA authorisation.
Documentation: No documentation legalises CBD — it is a Class A drug and even a foreign prescription does not permit entry; any cannabinoid medicine needs case-by-case HSA authorisation.

Clonazepam

Legal status: Clonazepam is a prescription-only 'poison' under the Poisons Act (Cap. 234) and its Rules; it is NOT listed on the Misuse of Drugs Act First Schedule, so it sits below the controlled-drug tier.
Consequences if caught: Unauthorised possession or supply of a prescription poison draws a fine and/or up to ~2 years (Poisons Act s.16). Singapore's death penalty (MDA Second Schedule) applies only to narcotics and amphetamine-type drugs above trafficking weights — benzodiazepines are not death-eligible.
If prescribed / medical: Dispensed as a prescription-only poison.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.

Cocaine

Legal status: Controlled drug under the Misuse of Drugs Act
Consequences if caught: Trafficking: more than 30 g — death penalty; less than 20 g — 5–20 years + 5–15 strokes; 20–30 g — 20–30 years/life + 15 strokes. Possession: less than 20 g — up to 10 years or S$20,000 or both. Consumption: 1–10 years + up to S$20,000. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

Codeine

Legal status: Codeine is a Class B controlled drug under the Misuse of Drugs Act 1973; it carries no capital threshold and sits below the capital tier (the Second Schedule death penalty applies only to named opioids such as morphine above 30 g and diamorphine above 15 g).
Consequences if caught: Unauthorised possession or supply draws imprisonment and caning under the MDA; codeine is not death-eligible.
If prescribed / medical: Dispensed as a Class B controlled prescription medicine.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.

Crack Cocaine

Legal status: Crack is the freebase (base) form of cocaine and has no separate legal identity in Singapore: it is controlled AS cocaine, a Class A controlled drug under the Misuse of Drugs Act, whose First Schedule entry covers cocaine, its salts and any preparation containing it and thus reaches the base/freebase form. The MDA's capital-trafficking threshold for cocaine (Second Schedule) is measured by the weight of cocaine present and therefore carries over to crack: trafficking above 30 g of cocaine is capital-eligible whether the cocaine is in powder or base/freebase form.
Consequences if caught: Possession of crack (as cocaine) carries up to 10 years and/or fines; trafficking above 30 g of cocaine attracts the death penalty (discretionary in limited circumstances) on the same weight-of-cocaine basis as powder.
If prescribed / medical: Cocaine has no recognised therapeutic use in Singapore; the crack/freebase base has no medicinal preparation and cannot be prescribed.
Documentation: No prescription documentation exists for crack/freebase cocaine.

Delta-8-THC

Legal status: Controlled — delta-8-THC (Δ8-THC) is caught under the Misuse of Drugs Act 1973 First Schedule, which lists Cannabinol, cannabinol derivatives and tetrahydrocannabinols; delta-8 is controlled as a tetrahydrocannabinol/cannabinol derivative (Class A), with no US-style hemp exemption. Distinct from cannabis; the mandatory-death thresholds (Second Schedule) are plant-form/weight specific — cannabis 500 g, cannabis mixture 1000 g — so whether a pure delta-8 tetrahydrocannabinol reaches the capital tier is left to confirmation.
Consequences if caught: Zero tolerance; long imprisonment and caning for Class A trafficking. Consumption alone carries up to 10 years; nationals prosecutable for consumption abroad.
If prescribed / medical: No recognised medical use; delta-8-THC is not a prescribable medicine.
Documentation: No lawful personal import; treat as zero tolerance.

DMT

Legal status: Class A controlled drug — Misuse of Drugs Act, First Schedule (Part 1)
Consequences if caught: Trafficking, possession, and consumption are MDA offences carrying severe penalties — imprisonment and caning; trafficking above statutory thresholds can carry the death penalty. The per-substance gramme threshold was not separately retrieved — verify with CNB / the MDA Second Schedule. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.

DXM

Legal status: Over-the-counter cough medicine, NOT a controlled drug. Dextromethorphan (DXM) is a non-prescription antitussive (regulated as a pharmacy/general-sale therapeutic product and a Poison under the Poisons Act) — it is NOT listed as a controlled drug under the Misuse of Drugs Act, so it carries no MDA (capital/trafficking) exposure.
Consequences if caught: No Misuse of Drugs Act offence; unlicensed sale or supply of DXM outside the therapeutic-products/poisons framework is an HSA regulatory offence.
If prescribed / medical: Cough-suppressant status: OTC — dispensed without a prescription (pharmacy/general sale).
Documentation: DXM cough medicine is bought over the counter in Singapore without a prescription.

Gabapentin

Legal status: Gabapentin is a Prescription Only Medicine (POM) under the Health Products Act, not a controlled drug: it is HSA-registered as a therapeutic product and does not appear in the schedules of the Misuse of Drugs Act. Singapore, despite its strict drug regime, treats gabapentin as an ordinary prescription medicine rather than a controlled drug.
Consequences if caught: Gabapentin falls outside the Misuse of Drugs Act, so Singapore's controlled-drug penalties do not reach this approved medicine; unauthorised sale of a POM is a Health Products Act offence.
If prescribed / medical: Prescribed for epilepsy and neuropathic pain; classified Prescription Only in the HSA/National Drug Formulary.
Documentation: Gabapentin is HSA-registered and listed in the National Drug Formulary; travellers may bring up to three months' supply of this non-controlled prescription medicine with a prescription.

Hydrocodone

Legal status: Hydrocodone is a Class A controlled drug under the Misuse of Drugs Act 1973; it is not marketed in Singapore and is NOT named in the capital Second Schedule (which lists morphine, diamorphine and opium), so it carries no drug-named death threshold and is not death-eligible (confirmed).
Consequences if caught: Unauthorised possession or consumption of a Class A drug carries imprisonment and/or caning and trafficking is heavily penalised — but hydrocodone is absent from the capital Second Schedule, so the mandatory-death trafficking tier does not attach to it.
If prescribed / medical: No marketed Singapore hydrocodone product; a Class A opioid is dispensed only under controlled-drug authority.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on the HSA personal-medication check.

Below tier: the MDA Second Schedule mandatory-death thresholds are drug-specific (diamorphine 15g, meth 250g, cocaine 30g, cannabis 500g etc.) and do NOT include cathinone, so khat carries no death exposure.
Consequences if caught: Zero-tolerance: even trace khat is an arrestable Class A offence carrying jail and possible caning, but not capital — cathinone is not a capital-threshold drug.
If prescribed / medical: Khat is traditional plant material with no recognised medical use and no lawful prescription route.
Documentation: No lawful personal-import route; the plant is expressly named by CNB and possession alone is arrestable.

Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

MDA

Legal status: Controlled — MDA is a Class A controlled drug named in the First Schedule to the Misuse of Drugs Act 1973 (with MDMA and MDEA). NOT death-eligible: MDA is absent from the capital Second Schedule (which names only opium/morphine/diamorphine/cocaine/cannabis/methamphetamine) — confirmed. 10 g of the MDMA/MDA/MDEA combination raises a trafficking presumption only, capped below death.
Consequences if caught: Class A: trafficking punishable by long imprisonment (~20-30 years) plus caning; consumption/possession severe — but NOT the death penalty for MDA-class amounts.
If prescribed / medical: Class A controlled drug with no recognised medical use; no lawful prescription route.
Documentation: No lawful personal import; MDA-class amounts are non-capital but attract heavy prison and caning.

MDMA

Legal status: Controlled drug under the Misuse of Drugs Act
Consequences if caught: Trafficking: 5–20 years' imprisonment + 5–15 strokes of the cane (no capital threshold listed). Possession: up to 10 years or S$20,000 or both. Consumption: 1–10 years + up to S$20,000.

MDPV

Legal status: Controlled. MDPV is captured by a synthetic-cathinone generic group in the First Schedule to the Misuse of Drugs Act (Class A). It is below the capital tier and not death-eligible: Singapore's capital thresholds (MDA Second Schedule / s.33B) are named per-drug and no capital quantity is listed for synthetic cathinones including MDPV.
Consequences if caught: Illegal as a Class A drug; supply and trafficking carry imprisonment and caning, but MDPV has no capital threshold and is not death-eligible.
If prescribed / medical: MDPV has no recognised medical use and no lawful prescription route in Singapore.
Documentation: No lawful personal-import route for a Class A controlled drug; do not carry.

Memantine

Legal status: Memantine is a prescription-only medicine, not a controlled drug: it is registered as a therapeutic product with the HSA (e.g. Memantine Mevon, SIN15300P) and does not appear in the schedules of the Misuse of Drugs Act.
Consequences if caught: Memantine falls outside the Misuse of Drugs Act, so Singapore's controlled-drug regime does not reach this approved medicine; unauthorised sale of a POM is a Health Products Act offence only.
If prescribed / medical: Prescribed for moderate-to-severe Alzheimer's dementia.
Documentation: Memantine is HSA-registered and listed in the National Drug Formulary; travellers carry it lawfully with a prescription.

Mephedrone (4-MMC)

Legal status: Controlled — NAMED. Mephedrone is individually added to the First Schedule (Class A) of the Misuse of Drugs Act (Cap. 185) on 15 Nov 2010 (with BZP and TFMPP). It sits BELOW the capital tier: MDA mandatory-death trafficking applies only to substances with a Second Schedule capital quantity, and mephedrone carries no such threshold — no death-penalty exposure.
Consequences if caught: Class A: possession and trafficking offences carry imprisonment and caning, but mephedrone is not death-eligible (no Second Schedule capital quantity).
If prescribed / medical: Class A controlled drug with no recognised medical use and no lawful prescription route.
Documentation: No licit personal-carry or import route for a Class A drug.

Mescaline

Legal status: Illegal under the Misuse of Drugs Act — the plant/derivative contains a controlled substance (Mescaline)
Consequences if caught: Controlled-drug offences under the MDA carry severe penalties — imprisonment and caning; trafficking above statutory thresholds can carry the death penalty. The specific quantity threshold for this substance was not published on the source page — verify with CNB. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).

Methadone

Legal status: Methadone is a Class A controlled drug under the Misuse of Drugs Act 1973, but it is NOT listed in the capital Second Schedule (which names morphine, diamorphine and opium) — a controlled strong opioid, not death-eligible; confirmed.
Consequences if caught: Unauthorised possession or consumption of a Class A drug carries imprisonment and caning; trafficking is severe, but methadone is not among the death-eligible Second-Schedule drugs.
If prescribed / medical: Prescribed as a Class A controlled drug for supervised methadone-maintenance OST.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry (HSA).

Legal status: Controlled drug under the Misuse of Drugs Act
Consequences if caught: Trafficking: more than 250 g — death penalty; less than 167 g — 5–20 years + 5–15 strokes; 167–250 g — 20–30 years/life + 15 strokes.

Methaqualone (Quaaludes)

Legal status: Methaqualone is a Class C controlled drug in Part III of the First Schedule to the Misuse of Drugs Act — the named transposition of its 1971 Convention Schedule II status; a withdrawn hypnotic with no marketed medical use, historically abused in Singapore before the Act.
Consequences if caught: Unauthorised possession or consumption carries imprisonment and fines (and caning for certain offences); trafficking a Class C drug carries imprisonment and caning (the mandatory capital penalty applies only to the highest Class A quantities, not Class C).
If prescribed / medical: No recognised medical use / withdrawn — methaqualone is not a lawful prescription medicine.
Documentation: No medical or traveller route; there is no legitimate prescription supply.

Methylone

Legal status: Controlled under the Misuse of Drugs Act 1973 — methylone, as a synthetic cathinone, was brought under Class A (First Schedule) via the CNB NPS pipeline (reclassification of NPS from the Fifth to the First Schedule from 1 May 2019); NAMED-batch as an NPS, specific listing instrument left to confirmation. Serious control but BELOW the capital tier.
Consequences if caught: Zero tolerance; long imprisonment and caning for Class A trafficking. Not death-eligible: methylone is not on the drug-specific mandatory-death quantity list (Second Schedule — diamorphine 15 g, methamphetamine 250 g, etc.).
If prescribed / medical: No recognised medical use; no lawful prescription route.
Documentation: No lawful personal import; treat as zero tolerance.

Methylphenidate

Legal status: Class B controlled drug under the Misuse of Drugs Act 1973 (First Schedule) — lower than amphetamine (Class A).
Consequences if caught: Possession/use up to 10 years or S$20,000. Methylphenidate is Class B and NOT in the capital-trafficking schedule, so no capital exposure.
If prescribed / medical: Prescription ADHD/narcolepsy medicine (e.g. Ritalin/Concerta) via controlled channels; carry the original prescription and any required import permit.

Mitragynine

Legal status: Mitragynine, the principal alkaloid of kratom, is a Class A controlled drug under the Misuse of Drugs Act: mitragynine and 7-hydroxymitragynine are the named Class A entity and kratom leaf is prohibited because it contains them, so the alkaloids are controlled together with the plant. Class A carries severe penalties, but kratom's alkaloids are not among the narcotics in the MDA Second Schedule capital-trafficking thresholds, so they are not death-eligible.
Consequences if caught: Class A possession, import or trafficking carries heavy imprisonment and caning; the alkaloids sit below the MDA Second Schedule capital-trafficking tier.
If prescribed / medical: No lawful medical route — kratom's alkaloids are Class A controlled drugs with no medical use in Singapore.
Documentation: No lawful personal-import route for a Class A controlled drug.

Modafinil

Legal status: Therapeutic product (prescription; HSA import authorisation) under the Health Products Act 2007 — NOT a controlled drug in the Misuse of Drugs Act.
Consequences if caught: Unauthorised sale/supply: fine up to S$50,000 and/or up to 2 years; personal use is not a drug offence. No capital exposure (not MDA-scheduled).
If prescribed / medical: Personal import needs HSA authorisation; carry the prescription.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

Morphine

Legal status: Morphine is a Class A controlled drug under the Misuse of Drugs Act 1973 (First Schedule) and is death-eligible: trafficking more than 30 g of morphine carries the death penalty under the Second Schedule (s.33), and manufacture of morphine is capital at any quantity.
Consequences if caught: Unauthorised possession or consumption draws imprisonment and caning; trafficking above 30 g of morphine is death-eligible and manufacture is capital at any quantity (mandatory death now discretionary in narrow cases).
If prescribed / medical: Available on prescription as a Class A narcotic for severe and cancer pain, dispensed under strict controlled-drug records.
Documentation: Travellers need HSA approval to carry controlled narcotics; carry a doctor's letter and original packaging and declare on entry (typically up to a 30-day supply).

sso.agc.gov.sg · Updated July 13, 2026

Morphine in Singapore, full detail →

Nicotine

Legal status: Nicotine itself is legal in Singapore as a tobacco constituent and in licensed nicotine-replacement therapy (patches, gum, lozenges). The nicotine DELIVERY product is the divergence: e-vaporisers and all imitation/emerging tobacco products are outright PROHIBITED. Since 1 February 2018 the purchase, use and possession of e-vaporisers has been an offence, and the Tobacco and Vaporisers Control Act (passed 6 March 2026, in force 1 May 2026) consolidates and sharply increases the penalties. This is a genuine, safety-critical traveler trap.
Consequences if caught: Possessing, using or buying an e-vaporiser is an offence carrying a maximum fine raised to S$10,000; enforcement is active, with airport and street checks. Import, distribution or sale attracts far heavier penalties, and devices are seized on entry — travelers should carry no vape hardware or e-liquid into Singapore.
If prescribed / medical: Nicotine-replacement therapy is legally available as a medicinal product; there is no lawful prescription or medical route to obtain a vaping device.
Documentation: No permit exists for e-vaporisers — they are contraband; travelers must declare/surrender none because possession itself is prohibited.

Nitrous Oxide

Legal status: Nitrous oxide is not listed as a controlled drug under the Misuse of Drugs Act; the Singapore Food Agency permits it as a food additive under the Food Regulations and the Health Sciences Authority regulates therapeutic nitrous-oxide products, so its status is that of a food and medical gas rather than a narcotic.
Consequences if caught: As a non-scheduled substance it carries no Misuse of Drugs Act penalty and is NOT death-eligible; recreational misuse is addressed through public-health warnings and product regulation.
If prescribed / medical: Nitrous oxide is a lawful food additive (whipped-cream propellant, E942) and a regulated therapeutic/anaesthetic gas via HSA registration.
Documentation: Food-grade nitrous oxide is a permitted additive; recreational inhalation is discouraged by the authorities, but the gas is not a controlled drug.

Oxycodone

Legal status: Oxycodone is a Class A controlled drug under the Misuse of Drugs Act 1973 — a controlled strong opioid; it is NOT in the capital Second Schedule (which names morphine, diamorphine and opium only), so oxycodone is not death-eligible (confirmed).
Consequences if caught: Unauthorised possession or consumption draws imprisonment and/or caning; Class A trafficking carries heavy imprisonment and caning. The Second Schedule death thresholds (e.g. above 30 g of morphine) apply to the named narcotics only — oxycodone is not death-eligible.
If prescribed / medical: Dispensed as a Class A controlled drug on prescription; a licence is needed to import.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on the HSA personal-medication check.

Oxycodone in Singapore, full detail →

PCP

Legal status: Class A controlled drug — Misuse of Drugs Act, First Schedule (Part 1)
Consequences if caught: Trafficking, possession, and consumption are MDA offences carrying severe penalties — imprisonment and caning; trafficking above statutory thresholds can carry the death penalty. The per-substance gramme threshold was not separately retrieved — verify with CNB / the MDA Second Schedule. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.
Documentation: Original packaging + doctor's prescription; check Singapore's HSA / apply for approval for personal medication.

Peyote

Legal status: Illegal under the Misuse of Drugs Act — the plant/derivative contains a controlled substance (Mescaline, from Lophophora williamsii)
Consequences if caught: Controlled-drug offences under the MDA carry severe penalties — imprisonment and caning; trafficking above statutory thresholds can carry the death penalty. The specific quantity threshold for this substance was not published on the source page — verify with CNB. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).

Pink Cocaine / Tusi

Legal status: Pink cocaine (tusi) is not scheduled as such; it is a variable mixture (typically ketamine + MDMA) prosecuted through its constituents — both MDMA and ketamine are controlled drugs under the Misuse of Drugs Act, which reaches any preparation containing a controlled drug. Because the blend varies batch to batch, exposure follows the most-severely-controlled detected component; notably, neither ketamine nor MDMA is listed in the capital Second Schedule, so tusi is not death-eligible here.
Consequences if caught: Possession, consumption and trafficking are serious offences carrying imprisonment and caning, and trafficking of a threshold amount triggers a statutory presumption — but because neither constituent is a Second-Schedule capital drug, the mandatory death penalty does not apply.
If prescribed / medical: No lawful supply of the mixture; ketamine is a controlled medicine, while MDMA has no marketed medical use.
Documentation: Sold as a party powder of unknown makeup; because composition varies batch to batch, buyers and travellers cannot know its constituents, so heavy legal exposure (imprisonment and caning) under the Misuse of Drugs Act is unknowable at purchase.

cnb.gov.sg · Updated July 14, 2026

Poppers

Legal status: Poppers (alkyl nitrites) are NOT a controlled drug under the Misuse of Drugs Act — instead the alkyl nitrites (amyl, butyl, isobutyl nitrite) are prescription-only medicines regulated under the Health Products Act, so unregistered 'poppers' products (sold as leather cleaners/room odourisers) are unlawful therapeutic products whose sale and supply the HSA enforces against. Because they sit outside the MDA, they are not capital / not death-eligible.
Consequences if caught: Selling or supplying unregistered alkyl nitrite poppers is an offence under the Health Products Act (health-product/enforcement penalties), not a Misuse of Drugs Act trafficking offence; no death penalty applies.
If prescribed / medical: Alkyl nitrites are prescription medicines for supervised medical use; there is no lawful consumer/retail poppers product.
Documentation: Do not import for sale; the HSA seizes and acts against unregistered poppers, though they are not a controlled drug.

Pregabalin

Legal status: Pregabalin is a Prescription-Only Medicine (POM) under Singapore's Health Products Act and is NOT a controlled drug or psychotropic substance under the Misuse of Drugs Act — so, unlike genuine MDA controlled drugs, it carries no trafficking or capital exposure and is treated as a prescription medicine (as is gabapentin).
Consequences if caught: Unauthorised supply or possession of a POM draws a fine and/or imprisonment under the medicines/poisons regime; pregabalin is not death-eligible.
If prescribed / medical: Dispensed as a Prescription-Only Medicine.
Documentation: Carry it in original packaging with a valid prescription or doctor's letter for personal use only, and declare it on the HSA personal-medication check.

Psilocybin

Legal status: Illegal under the Misuse of Drugs Act — the plant/derivative contains a controlled substance (Psilocybin)
Consequences if caught: Controlled-drug offences under the MDA carry severe penalties — imprisonment and caning; trafficking above statutory thresholds can carry the death penalty. The specific quantity threshold for this substance was not published on the source page — verify with CNB. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.

Quetiapine

Legal status: Quetiapine is a prescription-only medicine, not a controlled drug: Seroquel, Seroquel XR and quetiapine generics are registered therapeutic products with the HSA (e.g. SIN09771P) and do not appear in the schedules of the Misuse of Drugs Act.
Consequences if caught: Quetiapine falls outside the Misuse of Drugs Act, so Singapore's controlled-drug regime does not reach this approved medicine; unauthorised sale of a prescription-only medicine is a Health Products Act offence only.
If prescribed / medical: Prescribed as an atypical antipsychotic for schizophrenia and bipolar disorder; dispensed only on prescription.
Documentation: Seroquel and quetiapine products are HSA-registered and listed in the National Drug Formulary; travellers carry it lawfully with a prescription.

Salvia divinorum

Legal status: Illegal under the Misuse of Drugs Act — the plant/derivative contains a controlled substance (Salvinorin A)

The specific quantity threshold for this substance was not published on the source page — verify with CNB. Drug offences can also carry caning; on entry, unannounced drug tests and property searches may apply, and residents can be prosecuted even for use outside Singapore (U.S. State Dept).
If prescribed / medical: If bringing a prescribed medication, you may need prior approval from the Health Sciences Authority (HSA); carry it in original packaging with your doctor's prescription. Illicit possession remains a drug offence regardless.

Scopolamine (Devil's Breath)

Legal status: Scopolamine (hyoscine) is a registered therapeutic product, not a controlled drug: hyoscine butylbromide (Buscopan, e.g. SIN03574P) is HSA-registered as a Pharmacy Only Medicine (P) and does not appear in the schedules of the Misuse of Drugs Act.
Consequences if caught: Hyoscine falls outside the Misuse of Drugs Act, so Singapore's controlled-drug regime does not reach this approved medicine; unauthorised sale of a P medicine is a Health Products Act offence only.
If prescribed / medical: Buscopan (hyoscine butylbromide) is a pharmacy-only antispasmodic obtained from a pharmacist without prescription; injectable scopolamine is used clinically.
Documentation: Buscopan is HSA-registered and listed in the National Drug Formulary as a Pharmacy Only Medicine; travellers carry it lawfully.

Synthetic Cannabinoids (K2 / Spice)

Legal status: Controlled as a class. Synthetic cannabinoids are captured by generic synthetic-cannabinoid groups in the First Schedule to the Misuse of Drugs Act (Class A) - three generic groups were added at paragraphs 20-22 with effect from 1 May 2017, subsuming earlier generic groups and 86 individually listed synthetic cannabinoids, and the schedule was further clarified in 2025. They are below the capital tier: Singapore's capital thresholds (MDA Second Schedule) are named per-drug and no capital quantity is set for synthetic cannabinoids.
Consequences if caught: Illegal as Class A drugs; supply and trafficking carry imprisonment and caning, but synthetic cannabinoids have no capital threshold and are not death-eligible.
If prescribed / medical: These synthetic cannabinoids have no recognised medical use and no lawful prescription route in Singapore.
Documentation: No lawful personal-import route for Class A controlled synthetic cannabinoids; do not carry.

Tramadol

Legal status: Tramadol is a Prescription-Only Medicine (POM) under Singapore's Health Products Act / Poisons framework (HSA) and is NOT a controlled drug under the Misuse of Drugs Act — it is not in the MDA First or Second Schedule, so no capital trafficking tier attaches to tramadol.
Consequences if caught: Unauthorised supply or possession of a prescription-only medicine draws a fine and/or imprisonment under the medicines/poisons regime; tramadol is not death-eligible.
If prescribed / medical: Dispensed as a Prescription-Only Medicine.
Documentation: Carry it in original packaging with a valid prescription or doctor's letter for personal use only, and declare it on the HSA personal-medication check.

Xanax (Alprazolam)

Legal status: Alprazolam is a prescription-only 'poison' under the Poisons Act (Cap. 234) and its Rules; it is NOT listed on the Misuse of Drugs Act First Schedule, so it sits below the controlled-drug tier.
Consequences if caught: Unauthorised possession or supply of a prescription poison draws a fine and/or up to ~2 years (Poisons Act s.16). Singapore's death penalty (MDA Second Schedule) applies only to narcotics and amphetamine-type drugs above trafficking weights — benzodiazepines are not death-eligible.
If prescribed / medical: Dispensed as a prescription-only poison.
Documentation: Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.

Legal status: Zolpidem is a psychotropic substance regulated by the Health Sciences Authority, transposing its 1971 Convention Schedule IV status; it is a prescription-only medicine and its import always requires prior HSA approval.
Consequences if caught: Unauthorised import or supply of this psychotropic without HSA approval is an offence under Singapore's strict controlled-drugs and psychotropic-substances regime, carrying severe penalties.
If prescribed / medical: Zolpidem is prescribed short-term for insomnia and obtained only on a valid Singapore prescription.
Documentation: A traveller must apply for HSA prior approval at least two weeks before arrival to carry zolpidem, generally limited to a three-month supply reviewed case by case.
