From the Research
Vaping is not directly linked to intracranial hemorrhage (head bleeds) based on current evidence, but it may increase the risk of stroke and affect blood vessel function. The most recent study, published in 2023 1, found no definitive causal relationship between vaping and intracranial hemorrhages. However, other studies suggest that vaping may increase blood pressure and affect blood vessel function, which are risk factors for hemorrhagic strokes 2, 3. Vaping products contain nicotine, which can raise blood pressure acutely and potentially damage blood vessel walls over time. Additionally, some vaping products contain compounds that may promote inflammation and oxidative stress, potentially compromising vascular integrity.
Some studies have investigated the effects of vaping on stroke outcomes, with one study finding that electronic cigarette vape exposure exacerbates post-ischemic outcomes in female but not in male rats 3. Another study found that vaping may increase the risk of stroke and affect blood vessel function, particularly in young adults 1. However, the evidence is still limited, and more research is needed to fully understand the relationship between vaping and intracranial hemorrhage.
Key points to consider:
- Vaping may increase blood pressure and affect blood vessel function, which are risk factors for hemorrhagic strokes
- Vaping products contain nicotine, which can raise blood pressure acutely and potentially damage blood vessel walls over time
- Some vaping products contain compounds that may promote inflammation and oxidative stress, potentially compromising vascular integrity
- Traditional risk factors for intracranial hemorrhage include uncontrolled hypertension, smoking, excessive alcohol use, certain medications (particularly blood thinners), and underlying vascular abnormalities
- Anyone experiencing sudden severe headache, confusion, weakness on one side of the body, or difficulty speaking should seek immediate medical attention regardless of vaping status, as these could indicate a brain bleed requiring urgent treatment.
If you currently vape and are concerned about stroke risk, consider discussing cessation strategies with your healthcare provider 1, 2.
