Cannabis, Cocaine, and Amphetamines Linked to Up to 174 Percent Higher Stroke Risk in Adults Younger Than 55
Learn about a study of over 100 million people that found a direct causal link between recreational drug use and stroke risk, even in younger populations.
Cocaine, amphetamines, and cannabis use may elevate the risk of stroke by up to 174 percent in young adults, according to a comprehensive analysis of over 100 million people. Published in the International Journal of Stroke, the study indicates these drugs directly contribute to an increased likelihood of a blocked or ruptured blood vessel in the brain.
Cocaine use was found to raise stroke risk by 96 percent, while amphetamine use increased risk by 122 percent. Cannabis use was linked to a 37 percent higher risk. These associations remained significant when focusing on individuals under the age of 55. Amphetamine use was associated with a 174 percent increase in stroke risk — nearly three times greater than the baseline risk.
The findings underscore the importance of addressing substance abuse as a means of reducing stroke risk, as stroke is the third leading cause of both death and disability worldwide and many of its risk factors can be modified. Experts emphasize that drug use itself, rather than lifestyle factors, is the primary driver of elevated stroke risk.
