Educational Pearls:

  • Some synthetic cannabinoids have been contaminated with Brodifacoum. Brodifacoum is a Vitamin K antagonist and can present with a severe coagulopathy.
  • Brodifacoum is commonly known as “superwarfarin” and has a very long half life of 120+ days.
  • Check PT/INR in patients with a bleeding diathesis in setting of synthetic cannabinoid use.
  • Treatment is activated charcoal and large doses of Vitamin K (10mg Q6H for months).
