If you think you’re the only one you know lighting up, you probably aren’t. A new study shows that more adults than ever before are using cannabis daily, whether it’s to unwind at the end of the day or to lower their pain.

The study, out of Columbia University’s Mailman School of Public Health, looked at rates of cannabis use between 2007 and 2014 in all adults over 12 in the United States.

They found that both daily and nondaily cannabis use had decreased before 2007, and increased in most age groups between 2007 and 2014. Young people were most likely to increase their cannabis use, specifically adults between 26 to 34, whose non-daily cannabis use increased by almost five per cent.

The researchers can’t say why this might be for certain, but they believe it might have something to do with the fact that the number of states where cannabis is legal, whether for medical or recreational use, doubled over that time period, from 12 to 24.

“Increases in daily and nondaily cannabis use among adults after 2007 could be due to increasingly permissive cannabis legislation, attitudes, and lower risk perception," said Pia M. Mauro, one of the authors of the study.

They also found that the only group of adults whose non-daily use rates increased both before and after 2007 was between ages 50 and 64, which is something the researchers want to further explore.

It means both that baby boomers, who grew up in the war on drugs, are increasingly seeing cannabis as something they enjoy. Also, the number of seniors using it defies the stereotype that old people don’t get high.
