Study: Smoking pot increases risk of stroke
Researchers analyzed data on 160 stroke patients, aged 18 to 55, who were admitted to hospitals and had urine tests.
The stroke patients were twice as likely to test positive for marijuana as other hospital patients who had not suffered strokes.
The lead author says it’s the first case-controlled study to show a possible link to an increased risk of stroke from marijuana.
But the researchers acknowledge that all but one of the stroke patients who were pot users also smoked tobacco, calling into question which substance had the effect.
