Is LSD legal in South Korea?
- Legal status
- Controlled — psychotropic (LSD) under the Narcotics Control Act
- Consequences if caught
- LSD is among the controlled psychotropics. Possession or use of narcotics/psychotropics (e.g. methamphetamine/'philopon', cocaine, heroin) carries a minimum of 1 year's imprisonment; import, export, manufacture, or trafficking carries 5 years to life. Distinctively, South Korea prosecutes its own citizens for drug use committed abroad even where it was legal there (hair-follicle testing on return, up to 5 years); foreign nationals face deportation and a re-entry ban.
- If prescribed or medical
- Not a traveller medicine; controlled-substance medicines require MFDS advance approval before travel (see below).
- Documentation
- MFDS advance approval is required for controlled-substance medicines (including CBD/THC oil, amphetamines, opiates, and benzodiazepines) — apply online before travel (email narcotics@korea.kr). Non-controlled medicines are allowed up to 6 bottles / a 3-month supply with a prescription and a doctor's letter.
