Amphetamine, dextroamphetamine and methamphetamine, are collectively referred to as amphetamines. Their chemical properties and actions are so similar that even experienced users have difficulty knowing which drug they have taken.

  • Increased wakefulness.
  • Increased physical activity.
  • Decreased appetite.

Symptoms may last for days with occasional use and weeks or months with chronic use, with severity dependent on the length of time and the amount of methamphetamine used. Withdrawal symptoms may also include anxiety, irritability,headaches, agitation, restlessness, excessive sleeping, vivid or lucid dreams, deep REM sleep, and suicidal ideation

In 2007, 4.5% of American high-school seniors and 4.1% of tenth grade students reported using methamphetamine at least once in their life.

In the United States, the percentage of drug treatment admissions due to methamphetamine and amphetamine abuse tripled from 3% in 1996 to 9% in 2006. Some states have much higher percentages, such as Hawaii, where 48.2% of the people seeking help for drug or alcohol abuse in 2007 were methamphetamine users.
