Researchers at the University of Cambridge found that using cannabis, cocaine, and amphetamines increases the risk of stroke. The study analyzed data from over 100 million people and showed that these drugs can lead to a higher risk of stroke, especially in younger users.
A team of researchers from the University of Cambridge Department of Clinical Neurosciences conducted a massive study on the link between recreational drug use and stroke risk. They used data from more than 100 million participants to analyze the connection between these drugs and stroke.
The study found that cannabis, cocaine, and amphetamine use were each linked to a significantly higher risk of stroke. Cocaine and amphetamines increased the risk by about twice, while cannabis use was associated with an increase of about 37%. Opioid use showed no significant association with stroke risk.
The researchers also examined people under age 55 separately and found that amphetamine use was linked to nearly three times the risk of stroke in this younger group. Cannabis was linked to a smaller 14% increase in stroke risk, while cocaine use was associated with a 97% increase.
To determine whether these relationships were causal or just associated, the researchers used Mendelian randomization, a statistical method that examines naturally occurring genetic variants connected with risk factors and stroke. They found that cocaine use disorders were especially associated with brain hemorrhage and cardioembolic stroke, while cannabis use disorders were associated with stroke overall and particularly linked to large artery stroke.
The study's findings have important implications for public health, as recreational drug use is widespread among young people. In 2024, 8.8% of adults between ages 16 and 59 in England and Wales reported using a legal or illegal recreational drug during the previous year.
Why It Matters
This study's findings are important because they show that recreational drug use can lead to serious health problems, including stroke. As many Indian students may be exposed to these drugs, it's essential for them to understand the risks and make informed choices about their health.
