Smoking pot precipitates narrowing of brain vessels and probably risk of stroke.
As marijuana (cannabis) use increases, particularly in the young, there is growing concern that younger (under 50) users are at higher risk for ischemic strokes. French research had found regular cannabis users were 3 times as likely to experience intercranial stenosis (narrowing of brain arteries) as non-pot smokers. More research is needed to determine if this finding is causally linked to cannabis use.
PositiveTip: Many think marijuana use is safe, but it does carry serious health risks.
