To prevent illicit narcotics from entering our territory, Taipei Customs has intensified its enforcement efforts and inspection operations in this regard. Around 4,886 kilograms of illegal narcotics have been seized this year, demonstrating our determination and effective execution. Among these seizures, 594 kilograms of heroin, a Category I narcotic, and 1,602 kilograms of marijuana and its derivatives, classified as Category II narcotics, were intercepted, both reaching record highs.

According to statistics, heroin seizures increased significantly from 227 kilograms in 2023 and 318 kilograms in 2024 to 594 kilograms in 2025. Heroin is a highly addictive substance that induces intense euphoria, pleasure, and detachment from reality. In this respect, drug abusers often share injection needles, which poses serious public health risks and increases the spread of infectious diseases within the community.

In addition, the volume of intercepted marijuana and its derivatives has also surged from 480 kilograms in 2023 and 897 kilograms in 2024 to 1,602 kilograms in 2025. Although cannabis has been legalized in some countries, it remains illegal in Taiwan and is classified as a Category II narcotic under the Narcotics Hazard Prevention Act. Research indicates that cannabis use may harm the brain, lungs, and hearts. Long-term consumption can impair memory, learning ability, and cognitive function, potentially leading to drug tolerance and psychological dependence. Thailand, for example, once permitted recreational cannabis use, but revised its policy in June 2025 following a sharp rise in usage and related social and health concerns.

In alignment with the New Generation Anti-Drug Strategy, Taipei Customs will continue to strengthen cooperation with domestic and international law enforcement agencies to suppress drugs smuggling to ensure border security.
