Trends in Prevalence of Crystal Meth (Ice) Use Among Youth in the US, 1990-2012

"Measures on the use of crystal methamphetamine (ice) (a crystallized form of methamphetamine that can be smoked, much like crack) have been included in MTF [Monitoring The Future] since 1990. The use of crystal methamphetamine increased between the early and late 1990s among the three populations asked about their use: 12th graders, college students, and young adults. However, use never reached very high levels. The estimates are less stable than usual due to the relatively small samples asked about this drug, but it appears that among 12th graders crystal methamphetamine use held fairly steady from 1999 through 2005 (when it was 2.3%); since then it has declined to 0.8% in 2012. Use rose somewhat among college students and other young adults until 2005, before dropping substantially since then. After their peak levels were reached in 2005, college students and young adults showed substantial drops in annual prevalence to 0.6% by 2012."
