The list of controlled substances in Indonesia is included in Law No 35 of 2009, which is divided into three schedules, Type I (Golongan Satu), Type II (Golongan Dua), and Type III (Golongan Tiga), based on their addictive potential, with Type I regarded as having the highest possibilities of resulting in severe addiction.
