Cannabis use among adults younger than 45 years of age may dramatically increase their risk of heart attack, according to new research out of the Canadian Medical Association Journal.

Of the 33,000 adults between the ages of 18 and 44 surveyed by the U.S. Centers for Disease Control and Prevention, 17% said they had used cannabis in the last month. Overall, 1.3% of all cannabis users suffered from a heart attack, compared to only .8% of non-users, according to a press release.

"With recent legalization and decriminalization, cannabis use is increasing in young adults in North America, and we do not fully know its effects on cardiovascular health,” Dr. Karim Ladha, a clinician scientist at Unity Health Toronto, said in a media release. “We found an association between recent cannabis use and myocardial infarction, which persisted across an array of robust sensitivity analyses. Additionally, this association was consistent across different forms of cannabis consumption, including smoking, vaporization, and other methods such as edibles. This suggests that no method of consumption is safer than another in this regard.”

While data showed cannabis users were more likely to smoke cigarettes, vape and be heavier drinkers, KRQE reports that these factors, which also increase a user's risk for heart attack, were accounted for in the study.

Recreational marijuana use became legal in New Mexico on June 29, according to KRQE.
