Is Weed Legal in South Korea?

Recreational cannabis is illegal in South Korea and has been since the Cannabis Control Act of 1976, which was later consolidated into the Act on the Control of Narcotics, Etc. (Narcotics Act). Use, possession, cultivation, or trafficking can lead to imprisonment of up to five years or a fine of up to 50 million KRW for simple possession; supply and cultivation carry up to ten years. South Korea's nationality-based jurisdiction means Korean citizens can be prosecuted for cannabis use abroad, even in places where it is legal, such as Canada or several US states.

The Ministry of Food and Drug Safety (MFDS) is the lead regulator, with the Supreme Prosecutors' Office and National Police Agency handling enforcement. Drug testing is routine for celebrities, athletes, and military conscripts, and high-profile cases regularly produce custodial sentences. Diplomatic and consular warnings from MFDS in 2018 reaffirmed that overseas use remains punishable on return.
