Using marijuana doubles the risk of dying from heart disease, especially from stroke and heart attacks, a large new study found.

The evidence is stacking up that the drug is associated with a greater likelihood of heart problems. While most Americans consider marijuana safe, new research published this week found that use of the drug is associated with a higher risk of stroke and heart attack, including among younger adults.

A major new review published on June 17 in the medical journal Heart has raised alarms about the cardiovascular risks of marijuana, suggesting it may pose a greater threat for heart attack, stroke, and cardiovascular death than other illicit drugs like cocaine and opioids.
