I have heard Korea has extremely strict drug laws?

Korea has some of the strictest drug laws in the world, and the consequences for foreigners are severe. Even substances that are legal in your home country, like marijuana, are treated as serious crimes here. Possession alone can mean up to 5 years in prison, and trafficking can mean life imprisonment or the death penalty.

Key points every foreigner must know. First, Korean law applies to Korean citizens and residents even when they consume drugs abroad. If you use marijuana legally in Canada or Thailand and return to Korea, you can still be prosecuted. Random urine and hair tests have been used on returning travelers.

Second, common Western medications can be illegal in Korea. Adderall and other ADHD stimulants, certain sleep aids, and even some cold medicines containing pseudoephedrine require special documentation. Always check with the Korean Customs Service or bring a prescription with a doctor's note before flying.

Third, association matters. Being present at a gathering where drugs are used can lead to questioning and tests. If you see drug use, leave immediately. Conviction usually results in deportation and a permanent ban from re-entering Korea. When in doubt, do not bring or take anything questionable.
