Amphetamine Type-Stimulants (ATS)

Amphetamine-type stimulants (ATS) are a group of substances comprised of synthetic stimulants, including amphetamine, methamphetamine, methcathinone, and ecstasy-type substances (e.g. MDMA and its analogues). In various sections of this website, amphetamine and methamphetamine are also referred to as amphetamines. In cases where countries and media outlets reported to UNODC without indicating the specific ATS they are referring to, the term non-specified ATS was used. Often drug use surveys in South America, Central America and the Caribbean do not differentiate between the use of amphetamines (methamphetamine and amphetamine) and non-medical use of prescription ATS, by using the term "stimulants".
