University of Calgary finds adults with cannabis use disorder at higher risk of cardiovascular disease

A study found Canadian adults with cannabis use disorder have an approximately 60% higher risk of experiencing their first heart attack, stroke or other major cardiovascular event than those without cannabis use disorder. Within the group of people with cannabis use disorder, people with no co-occurring medical illness, no prescriptions and fewer than five visits to health services in the last six months had an even higher risk of a first-time cardiovascular disease event - approximately 1.4 times higher than for the rest of the cannabis-use-disorder group. Researchers say this may be because those people considered themselves healthy and may not have acted on or even noticed the warning signs of an imminent heart attack, stroke or other major cardiovascular event.
