Abuse of new psychoactive substances (NPSs) among youths is increasing at an unprecedented rate all over the world. In Asia, abuse of synthetic cannabinoids (SCs), kratom, and poppers has been reported, but up to date information related to abuse of these three NPSs is lacking. This literature review focuses on the recent abuse of these three NPS among Asian youth. Many studies have been conducted to investigate the abuse statuses of SCs in Asian youth in Turkey, Japan, and Korea, and many cases of kratom abuse have been reported in Malaysia and Thailand. In addition, concerns have been expressed about the use of kratom in combination with other substances by teenagers. Popper abuse has been reported among many young people in Asia, including Korea and China, and many studies on popper abuse have focused on men who have sex with men in China and Malaysia. Since NPS abuse can have severe adverse effects and create social problems, there is a continuing need to investigate NPS abuse status continuously among young people.
