Sources: 4. Developments: 2. In September 2026, South Korean lawmaker Seo Young-seok proposed an amendment to the Narcotics Control Act. The proposal sought to expand theft and leakage prevention requirements to all types of narcotics, addressing a regulatory loophole where obligations were previously limited to medical narcotics. This was intended to cover substances such as raw pharmaceutical ingredients and narcotics used for academic research. By October 2026, the National Assembly passed several legislative amendments, including a revised Narcotics Control Act. The new laws grant judicial police officers the authority to conduct drug tests on medical professionals or handlers suspected of illegal drug use. Furthermore, the legislation introduces punitive fines and the public disclosure of disciplinary actions for serious violations involving the illegal leakage or misuse of narcotics. ## Timeline ### 2026-10-01: South Korea passes laws to tighten narcotics control and medical supply management South Korea passed four law amendments to tighten narcotics control, institutionalize rare medicine support, manage essential medical device supplies, and combat counterfeit cosmetics. 2 sources. https://clstr.news/cluster/south-korea-passes-laws-to-tighten-narcotics-control-and-medical-supply-management ### 2026-09-02: Seo Young-seok proposes expanding narcotics theft prevention duties South Korean lawmaker Seo Young-seok proposed an amendment to expand theft and leakage prevention duties from only medical narcotics to all types of narcotics to close regulatory loopholes. 2 sources. https://clstr.news/cluster/seo-young-seok-proposes-expanding-narcotics-theft-prevention-duties --- Cite as: South Korean narcotics control legislative updates.
