Methamphetamine is a highly addictive psychostimulant drug that is a derivative of amphetamine. Methamphetamine can produce euphoria and stimulant effects like those from other stimulants such as cocaine. In addition, methamphetamine is easily synthesized from inexpensive and readily obtainable chemicals. These characteristics have led to widespread and rampant abuse worldwide, currently estimated at 33 million users based on the 2016 United Nations Office on Drugs and Crime World Drug Report. In the United States, there were greater than 150,000 emergency department visits for toxicity from methamphetamine in 2011 based on data from the Substance Abuse and Mental Health Services Administration. The Drug Enforcement Agency estimated there were 439,000 past-month methamphetamine users in 2011.
甲基苯丙胺是一种极易成瘾的精神刺激药物，是苯丙胺的衍生物。甲基苯丙胺能产生欣快感和刺激作用，类似于可卡因等其他兴奋剂。此外，甲基苯丙胺很容易由廉价且容易获得的化学品合成。这些特性导致其在全球范围内被广泛且猖獗地滥用，根据2016年联合国毒品和犯罪问题办公室《世界毒品报告》，目前估计有3300万使用者。在美国，根据物质滥用和精神健康服务管理局的数据，2011年因甲基苯丙胺中毒到急诊科就诊的人数超过15万。美国缉毒局估计2011年过去一个月有43.9万人使用甲基苯丙胺。
