Confirmed legal status

Cannabis / THC

Legal status: Recreational illegal, but private personal use is not punishable under the 'Arriola' doctrine (no fixed threshold); medical cannabis legal for registered patients
Consequences if caught: Possession of a personal-use quantity (Art 14) carries 1 month–2 years. The 2009 Supreme Court "Arriola" ruling held Art 14's penalty unconstitutional for consumption in private that harms no one else (Constitution Art 19) — BUT that ruling binds only its own case: lower courts vary, police still arrest, and there is NO fixed gram threshold. DISAMBIGUATION: decriminalized is NOT legalized — sale and purchase remain criminal, and Arriola prevents a conviction, not an arrest. Trafficking (Law 23.737 Art 5) — production, import, export, sale or supply — carries 4–15 years. For cannabis specifically, the Arriola doctrine means consumption in private is not punishable, but there is no statutory gram threshold and cultivation and sale remain criminal.
If prescribed / medical: Medical cannabis is legal for registered patients only (registry-based); recreational sale and purchase remain criminal offences.
Documentation: Medical cannabis is legal for registered patients only; recreational sale and purchase remain criminal offences. Carry any controlled medicine with its prescription and original packaging and confirm requirements with your embassy before travel.

Article 17: where dependence is established the court may suspend the sentence and order a curative security measure, and successful completion exempts the person from serving it.
If prescribed / medical: Cocaine has at most narrow controlled medical use; the crack/freebase base has no medicinal preparation and cannot be prescribed. Licit narcotics are dispensed under the ANMAT-administered controlled-substances regime; a prohibited street drug has no prescribable form.

Zolpidem

Legal status: Not confirmed — status not individually verified; confirm with Argentina's authorities (Law 23.737) / your embassy
Consequences if caught: This specific substance was not named in the cited Argentine sources (Law 23.737; CSJN 'Arriola' 2009) — do NOT assume it is permitted; verify before travel. Possession of a personal-use quantity (Art 14) carries 1 month–2 years. The 2009 Supreme Court "Arriola" ruling held Art 14's penalty unconstitutional for consumption in private that harms no one else (Constitution Art 19) — BUT that ruling binds only its own case: lower courts vary, police still arrest, and there is NO fixed gram threshold. DISAMBIGUATION: decriminalized is NOT legalized — sale and purchase remain criminal, and Arriola prevents a conviction, not an arrest. Trafficking (Law 23.737 Art 5) — production, import, export, sale or supply — carries 4–15 years.
If prescribed / medical: If a controlled medicine, carry the prescription and original packaging and confirm with your embassy (see documentation).
