Summary
Cannabis use may trigger cerebrovascular events, including ischemic stroke. A young man experienced a stroke shortly after marijuana consumption, with no other risk factors identified.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Toxicology
Background:
- Cannabis consumption is increasingly prevalent globally.
- Emerging evidence suggests a potential link between cannabis use and cerebrovascular events.
- Understanding these associations is crucial for public health and clinical practice.
Observation:
- A 37-year-old male with no prior medical history experienced a right occipital ischemic stroke.
- The stroke occurred approximately 15 minutes after smoking marijuana (approx. 250 mg).
- Symptoms included left-sided hemiparesis, hemi-hypesthesia, and blurred vision, which resolved within 3 days.
Findings:
- The patient reported regular cannabis use (2-3 joints/week) for 6 months prior to the event.
- Classical stroke risk factors such as hypertension, diabetes, and hyperlipidemia were absent.
- Extensive investigations ruled out other potential causes, including thrombophilia, vasculitis, and cardiac abnormalities.
Implications:
- This case suggests a potential causal link between chronic cannabis consumption and ischemic stroke.
- Further research is warranted to elucidate the mechanisms underlying cannabis-induced cerebrovascular events.
- Clinicians should consider cannabis use in the differential diagnosis of stroke, particularly in younger individuals without traditional risk factors.
