Cannabis use linked to 37% higher stroke risk in massive study
A massive analysis involving more than 100 million people has found strong links between recreational drug use and stroke, including among younger adults. Cocaine was associated with nearly double the risk of stroke, amphetamines with more than double the risk, and cannabis with a 37% increase.
A recent study led by researchers at the University of Cambridge has found that cannabis, cocaine, and amphetamines are linked to a significantly higher risk of stroke, particularly among younger individuals. The analysis, published in the International Journal of Stroke, examined data from over 100 million people and revealed that cocaine use increased stroke risk by 96%, amphetamines by 122%, and cannabis by 37%.
Younger users, under the age of 55, experienced an even more pronounced risk increase: amphetamine use was associated with a 174% higher risk, cannabis with a 14% increase, and cocaine with a 97% increase. The study also discovered that cocaine use disorders were linked to brain hemorrhage and cardioembolic stroke, while cannabis use disorders were associated with stroke in general, particularly large artery stroke.
Researchers from the Stroke Research Group at the University of Cambridge emphasized that these drugs are causal risk factors for stroke, rather than just associated factors, and called for public health measures to reduce substance abuse as a means of lowering stroke risk.
