"The East and South-East Asia region, which is home to about one-third of the global population, has one of the most established amphetamine-type stimulants (ATS) markets in the world, primarily for methamphetamine. Since the late 1990s, the illicit manufacture, trafficking and use of ATS have expanded significantly in the region. These trends continued in 2010. 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 Use 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. All 15 countries that contributed to this report reported significant levels of ATS use. In several of those countries, ATS drugs, particularly methamphetamine (in pill or crystalline form), have emerged as the primary drug threat in recent years, in some cases displacing traditionally used plant-based drugs such as heroin, opium or cannabis. It is estimated that between 3.5 and 20.9 million persons in East and South-East Asia have used amphetamines in the past year..."
