A stroke is a serious medical condition caused by damage to the brain’s blood vessels, hindering oxygen supply. This can lead to severe health consequences, including speech impairment, paralysis or even death. In the context of addiction and substance abuse, the term ‘stroke’ is particularly relevant due to the increased risk associated with certain drugs.

Various substances, particularly stimulants like cocaine, amphetamines and heroin, are known to elevate the risk of stroke. These drugs can directly harm the brain’s blood vessels or impact other organs in the body like the heart, kidneys or liver, indirectly contributing to stroke risk. For instance, heavy alcohol consumption can raise the likelihood of hemorrhagic stroke, a type of stroke caused by bleeding in the brain, primarily due to alcohol’s effect on blood pressure and blood-clotting mechanisms.

Cocaine use is strongly linked to strokes, potentially causing immediate strokes during use or cerebrovascular disease over time. The risks include dramatic blood pressure increases leading to bleeding in the brain, vessel narrowing or spasms and heart infections like endocarditis, which can lead to stroke. Similarly, heroin, particularly when injected, raises the risk of endocarditis, leading to strokes caused by bacterial clumps (septic emboli) traveling to the brain.

Amphetamines, including methamphetamine, are associated with stroke due to their capacity to induce sudden and extreme blood pressure spikes. Long-term methamphetamine use can cause abnormal functioning in brain blood vessels, increasing stroke risk.

Other substances linked to stroke include:

• Phencyclidine (PCP) or angel dust
• Lysergic acid diethylamide (LSD)
• Herbal viagra
• Marijuana
• Cigarettes
• Certain high-quantity energy drinks

Recognising stroke symptoms is vital for timely medical intervention. Key indicators include sudden one-sided numbness or weakness, speech difficulties, severe headache, dizziness and loss of coordination.

Prescription drug misuse, particularly pain relievers like oxycodone and fentanyl and sedatives, also pose a stroke risk. Misuse can slow breathing and reduce oxygen to the brain, potentially leading to stroke.

How To Identify a Stroke

Signs of a stroke in both men and women include sudden numbness or weakness, particularly on one side of the body, confusion or difficulty speaking and understanding, vision problems in one or both eyes, trouble walking, dizziness or loss of balance and coordination and a sudden, severe headache without a clear cause. It’s important to call emergency services immediately if these symptoms are observed.

Understanding the connection between substance abuse and stroke risk underpins the importance of avoiding addictive substances and seeking professional help for substance abuse issues. Recognising and addressing the risks early can be important in preventing the severe consequences of a stroke.
