New psychoactive substances in Taiwan: challenges and strategies

Purpose of review Abuse of new psychoactive substances (NPS) has been a new global concern. So far, there has been no international consensus on legislative control of NPS. Scrutiny of Taiwan's illegal drug use history reveals that legislation and policy play an important role in tackling the drug issues. Recent findings Since the early 2000s, use of club drugs (mostly NPS) has become popular in local rave parties and dance clubs in Taiwan. Some NPS, such as ketamine, synthetic cathinones, and para-methoxymethamphetamine, have posed a risk to public health and a challenge to drug policy. Summary The illegal drug use history in Taiwan was firstly briefly reviewed, and the recent NPS use situation was depicted. Heroin and methamphetamine have been the most predominant drugs, but NPS such as ketamine and synthetic cathinones have become a new issue. The toxicological profiles of commonly abused NPS in Taiwan, although limited, were discussed. By comparison of the legislative mechanism for NPS control between Taiwan, South Korea, and Japan, it was found that timely and flexible legislative mechanism(s) is essential for early identification, surveillance, and comprehensive evaluation. In addition, researches on NPS epidemiology and toxicology are needed to firm up evidence-based strategies for effective prevention, treatment, and harm reduction measures.
