"Amphetamine-type stimulants (ATS) are the second most widely used class of drugs worldwide, after cannabis. The East and South-East Asia region, which is home to about one-third of the global population, has some of the largest and most established ATS markets in the world. Methamphetamine in pill, powder and crystalline forms are the most widely used forms of ATS in the region. Demand for ecstasy remains high, although its use has declined. Since the late 1990s, the illicit manufacture, trafficking and use of ATS have expanded significantly in the region. These trends continued in 2011. The present report highlights the most current patterns and trends of amphetamine-type stimulants and other drugs of use in East and South-East Asia and provides overviews for the neighbouring regions of South Asia and the Pacific. This is the latest in a series of reports prepared under the Global Synthetics Monitoring: Analyses, Reporting and Trends (SMART) Programme. The objective of the Global SMART Programme is to enhance the capacity of Member States and relevant authorities to generate, manage, analyse, report and use synthetic drug information, in order to design effective, scientifically-sound and evidencebased policies and programmes. The findings of the report are based on primary information submitted by the drug control agencies and designated institutions in Brunei Darussalam, Cambodia, China, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand and Viet Nam, via the Drug Abuse Information Network for Asia and the Pacific (DAINAP) established through the Global SMART Programme. Information from DAINAP is supplemented with data from other Government sources such as national reports, the Annual Reports Questionnaire, and through primary and secondary research. Australia, Japan, New Zealand and Republic of Korea also provided data to the Global SMART Programme for this report..."
