Cannabis use can lead to arteritis, a serious vascular condition, particularly in young individuals. Early cessation of cannabis and appropriate medical treatment can improve outcomes for this condition.

Area of Science:

  • Vascular Medicine
  • Toxicology

Background:

  • Arteriopathy in young patients has diverse causes, including drug abuse, metabolic disorders, and specific diseases like Buerger's disease.
  • Cannabis indica-induced arteritis was first described in 1960, with later studies confirming its role as a risk factor.

Observation:

  • A 38-year-old male with a history of significant cannabis abuse presented with a necrotic lesion on his left big toe.
  • Imaging revealed proximal arteriopathy in the lower limbs, predominantly on the left side, in the absence of other common risk factors.

Findings:

  • The patient's arteritis developed concurrently with his cannabis abuse, suggesting a direct link.
  • The condition showed gradual improvement after cannabis cessation, vasodilator therapy, and hyperbaric oxygen treatment.

Implications:

  • Cannabis arteritis, while not widely recognized, may be an underdiagnosed cause of peripheral arterial disease, potentially a variant of Buerger's disease.
  • The findings highlight the vascular risks associated with cannabis consumption, possibly exacerbated by contaminants like arsenic.
