Does Illicit Drug Use Increase Stroke Risk?

Their results, published in the International Journal of Stroke, showed substantial differences in stroke risk associated with several drugs. Cocaine and amphetamine use were each linked to roughly twice the risk of stroke (cocaine increased the risk by 96%, amphetamines by 122%), while cannabis use was associated with an increase of about 37%. Opioid use, by contrast, showed no statistically significant association with stroke risk.

The researchers also examined people under age 55 separately. Within this younger group, amphetamine use was associated with nearly three times the risk of stroke (an increase of 174%). Cannabis was linked to a smaller 14% increase in stroke risk, while cocaine use was associated with a 97% increase.

Transient Ischemic Attack (TIA) – a Primer

The incidence of TIA in the United States is estimated to be 200,000-500,000 per year, with a prevalence of 5 million individuals, but is likely underreported.2 Stroke is preceded by TIA in 12-30% of patients and is the 5th leading cause of death in the US, contributing significantly to long term disability.2,3 Strokes occur more commonly in men than women, but women experience more severe morbidity.2,3 Stroke prevalence increases with age and occurs more frequently in black and Hispanic populations.3 It should also be noted that 90% of strokes worldwide occur in the setting of potentially modifiable risk factors which presents an incredible opportunity for early intervention, especially following TIA.2
