Trends in Methamphetamine Use by Young People in the US, 1999-2012
"Methamphetamine questions were introduced in 1999 because of rising concern about use of this drug; but a decline in use has been observed among all five populations in the years since then, although young adults did not show declines until 2005. In 2007 this decline continued in all five populations, and was significant in grades 8 and 12, with little further change thereafter, except for a jump up among 12th graders in 2011 and among young adults in 2012. In 2012 use in all five populations was at very low rates of annual prevalence — particularly among college students (0.2%). These substantial declines occurred during a period in which there were many stories in the media suggesting that methamphetamine use was a growing problem — an example of the importance of having accurate epidemiological data available against which to test conventional wisdom."
