Fewer young people are reporting that marijuana is ‘easy’ to obtain, according to an analysis released this week by the US Centers for Disease Control.
Investigators from the Substance Abuse and Mental Health Services Administration and the CDC evaluated annual data compiled by the National Survey on Drug Use and Health for the years 2002 to 2014. Researchers reported that the percentage of respondents aged 12 to 17 years who perceived marijuana to be “fairly easy or very easy to obtain” fell by 13 percent during this time period. Among those ages 18 to 25, marijuana’s perceived availability decreased by three percent.
Researchers further reported that “since 2002, the prevalence of marijuana use and initiation among U.S. youth has declined” – a finding that is consistent with numerous prior studies.
By contrast, authors reported an uptick in use among adults. However, they acknowledged that this increase in adult marijuana consumption has not been associated with a parallel increase in problematic use. There has been “steady decreases in the prevalence of marijuana dependence and abuse among adult marijuana users since 2002,” the study found. Those adults experiencing the greatest percentage increase in marijuana use during the study period were respondents over the age of 55.
A separate analysis of the data published in the journal Lancet Psychiatry similarly acknowledged no observed increase in marijuana use disorders. A previous assessment of marijuana use patterns since 2002, published earlier this year in JAMA Psychiatry, also reported a decline in the percentage of adults reporting problems related to their marijuana use.
