According to a recently published research in the Medical Journal JAMA Pediatrics, there was a drop in the use of Marijuana among the teens dropped in the United States that legalized the recreational use of the substance.
According to the research, Laws which legalized the recreational marijuana, which have been approved in 10 states & Washington, D.C. were linked with an 8% decline in the number of senior students who said they used marijuana in the past 30 days and a 9% drop in the number who said they had used it at least 10 times in the past 30 days.
There wasn’t any statistical link found between the medical marijuana laws & changes in youth usage by the researchers.
An associate professor who is also leading the research, Mark Anderson told the CNN that just to be clear, we did not found any effect on the teen use after the legalization for medical purposes, however proof of a likely reduction in use following legalization for recreational purposes.
He added on that due to our study being based on more policy variation than the previous work, we see our estimates as the most credible to date in the literature.
Data from 1993 to 2017 were analyzed by the researchers on around 1.4M high school students in the US from the U.S. Centers for Disease Control & Prevention’s annual national Youth Risk Behavior Surveys.
They found a link rather than a causal relationship.
Anderson added to the CNN that as there are many recreational marijuana laws been passed lately, we have observed limited post-treatment data for a few of these states. In the coming years, it would make sense to update our estimates as more there will be more availability of data.
