Summary
Daily cannabis users in a study of more than 434,000 U.S. adults were about 25% more likely to have had a heart attack and 42% more likely to have had a stroke than non-users.
A dose-response pattern emerged: non-daily users also showed elevated risk, and daily users who had never used tobacco or nicotine still had higher odds of heart attack, stroke or blocked arteries.
The analysis drew on CDC Behavioral Risk Factor Surveillance System data from 27 states and 2 territories, reflecting concern as cannabis use has risen and 19% of U.S. adults reported using it in 2021.
Researchers said the same pattern appeared in younger adults, including men under 55 and women under 65, though the self-reported, snapshot-style study shows association rather than proving causation.
