A new study in the American Medical Association’s Jama Psychiatry shows that marijuana use more than doubled from 2001-2002 to 2012-2013. In that time the percentage of adults in the U.S. who used cannabis in the past year went from 4.1% to 9.5%.
These numbers don’t come as a surprise to most people. It’s no secret that cannabis has become much more mainstream since the early ’00s. In fact, marijuana has become much more mainstream in just the last few years.
