Methamphetamine in the United States

Methamphetamine in the United States is regulated under Schedule II of the Controlled Substances Act. It is approved for extremely limited pharmacological use in the treatment of attention deficit hyperactivity disorder and treatment-resistant obesity, but it is primarily used as a recreational drug. In 2012, approximately 1.2 million Americans reported using methamphetamine in the past year; 440,000 reported using the drug in the past month.

Much of the methamphetamine consumed in the US is manufactured domestically by amateur chemists in meth labs from common household drugs and chemicals such as lye, lithium, and ammonia. Since the passage of the Combat Methamphetamine Epidemic Act of 2005, the Drug Enforcement Administration has reported a sharp decline in domestic meth lab seizures, but drug cartels continue to meet demand by manufacturing meth in Mexico and smuggling it across the border. In 2012, the DEA seized a total of 3,898 kg of methamphetamine and 11,210 meth labs. As of 2015^[update], the Sinaloa Cartel is the most active drug cartel involved in smuggling illicit drugs like methamphetamine into the United States and trafficking them throughout the United States.
