Yes, there are certain drugs that aren't allowed! I only know this because a friend got turned away when traveling and her entire vacation was ruined.
So to avoid this, you need to contact the MFDS at
[email protected] for specific guidance. You will have to obtain a permit for said medications prior to traveling to Korea.
Here are the drugs that are prohibited:
Narcotics and Opioids: Drugs containing codeine or other narcotics are strictly prohibited. Examples include certain painkillers and cough syrups.
Amphetamines and Stimulants: ADHD medications containing amphetamines, such as Adderall, are illegal to possess. While methylphenidate (e.g., Ritalin, Concerta) is available in Korea, it is tightly controlled, and bringing it in requires strict adherence to permit processes.
CBD and Hemp Products: All marijuana, CBD oil, and hemp-derivative products are heavily regulated and effectively banned for import; possession can lead to deportation or arrest.
Psychotropic Drugs: Certain sleeping aids (like Zolpidem) and benzodiazepines (like Xanax or Valium) are classified as controlled substances and require prior approval.
