There is no direct link between cocaine use and brain aneurysm. However, cocaine abuse can lead to high blood pressure, which is a known risk factor for brain aneurysms. Additionally, cocaine use can cause damage to blood vessels and arteries, which can also increase the risk of an aneurysm. It’s important to note that brain aneurysms are rare and not directly caused by cocaine use, but rather, the drug can indirectly contribute to the risk factors for aneurysms.
