There is some evidence to suggest that drug abuse, particularly stimulant abuse (e.g. cocaine, amphetamines), can increase the risk of developing a brain aneurysm. A brain aneurysm is a bulging or ballooning of a blood vessel in the brain that can potentially rupture, leading to a hemorrhagic stroke. However, it’s important to note that brain aneurysms can also occur without any prior drug use or other risk factors. Additionally, the evidence linking drug use to brain aneurysm is limited and more research is needed to fully understand this association. It’s important for individuals to avoid or limit drug use to reduce their risk of developing a range of health problems, including those related to the brain.
