Czech Republic List of Addictive Substances is established under the Addictive Substances Act (Act No. 167/1998 Sb.) and Government Regulation No. 463/2013 Sb. Following the structure of international drug control conventions, it divides substances into seven schedules of escalating control (with an additional Schedule 8 for preparations). It regulates traditional illicit drugs such as heroin, methamphetamine, cocaine, and LSD, as well as certain potent synthetic opioids. The list distinguishes criminal offences from misdemeanours by setting “larger quantity” thresholds; for example, possession of more than 1.5 grams of methamphetamine or heroin constitutes a criminal offence. The list is subject to ongoing updates: in 2026, HHC (hexahydrocannabinol) was transferred from the ZPL list to Schedule 4 (Psychotropic Substances), while 19 nitazene derivatives and spirochlorfin were added to Schedule 3 (Narcotic Drugs).
