(NewsNation) — A new study has found that people addicted to cannabis have a 60% higher risk of having their first heart attack or stroke compared to those who are not. 

The study published in the journal Addiction found that the risk was even higher for people who had no co-occurring medical illness, no prescriptions, and fewer than five visits to health services in the last six months.

The study collected data from 60,000 Canadian individuals, half of whom had an addiction diagnosis and half of whom did not. These participants were monitored from 2012 to 2019.

“Our study doesn’t provide enough information to say that cannabis use disorder causes adverse cardiovascular disease events, but we can go so far as to say that Canadians with cannabis use disorder appear to have a much higher risk of cardiovascular disease than people without the disorder.”
