Who uses crystal methamphetamine? Crystal methamphetamine is used by individuals of all ages and is increasingly gaining in popularity as a club drug. It is difficult to determine Who uses crystal methamphetamine? how many individuals in the United States use crystal methamphetamine because most illicit drug use surveys do not distinguish between crystal meth- amphetamine and powdered metham- phetamine. Those surveys that do draw such a distinction reveal that use of crystal methamphetamine is prevalent. According to the University of Michigan’s Monitoring the Future Survey, nearly 5 percent of high school seniors in the United States used crys- tal methamphetamine at least once in their lifetime and 3 percent used the drug in the past year.
