When Adolescents Give Up Pot, Their Cognition Quickly Improves
Marijuana, it seems, is not a performance-enhancing drug. That is, at least, not among young people, and not when the activity is learning.
A study published Tuesday in the Journal of Clinical Psychiatry finds that when adolescents stop using marijuana – even for just one week – their verbal learning and memory improves. The study contributes to growing evidence that marijuana use in adolescents is associated with reduced neurocognitive functioning.
More than 14 percent of middle and high school students reported using marijuana within the last month, finds a National Institutes of Health survey conducted in 2017. And marijuana use has increased among high schoolers over the past 10 years, according to the U.S. Department of Health & Human Services.
At the same time, the percentage of teens who believe that regular marijuana use poses a great risk to their health has dropped sharply since the mid-2000s. And, legalization of marijuana may play a part in shaping how young people think about the drug. One study noted that after 2012, when marijuana was legalized in Washington state, the number of eighth graders there that believed marijuana posed risks to their health dropped by 14 percent.
The use by youth is worrisome. People that young have no long-range planning skills - they do not think about what might happen 20-30 years later if they begin damaging habits.
