Question

Cannabinoids are metabolized by many of the same cytochrome P450 enzymes as warfarin, including CYP3A4, CYP2C9, and CYP2C19. THC, CBD and CBN can inhibit the CYP2C9-mediated hydroxylation of warfarin, and thus lead to an increase in INR. Do cannabinoids also affect the metabolism of heparin? Is the metabolism of direct oral anticoagulants (DOACs), including rivaroxaban, edoxaban, and apixaban, impacted by cannabinoids?
