StrokeSense : Are You At Risk?

Substance Abuse

Some substances, both legal and illegal, can increase people's risk for stroke.

Cocaine and crack cocaine cause the arteries to narrow, which can lead to stroke. Use of these drugs also causes the heart to beat rapidly and irregularly, which can cause blood clots to form.

Smoking marijuana also may be a risk factor for stroke. Even though it lowers blood pressure, smoking marijuana and cigarettes can cause fluctuating blood pressure levels and eventual blood vessel damage.

The use of amphetamines, heroin, and anabolic steroids also can lead to a stroke. Known as vasoconstrictors, these drugs can cause blood vessels to tighten and blood pressure to rise.

Caffeine and pseudoephedrine, found in many over-the-counter decongestants, also are suspected of causing stroke.
