Answer - Director, Cal State Caregivers Collective

Doctors that I have spoken with have expressed concerns about cannabis use and blood thinners. Our collective has a cannabis-friendly pharmacist as a consultant and is available to provide a phone consultation if you feel the need. Below is a case study published in PubMed that should give you pause before medicating while on warfarin. Good luck.

DISCUSSION: Marijuana may increase warfarin anticoagulant effect by inhibiting its metabolism, and to a lesser extent, displacing warfarin from protein-binding sites. Other causes (eg, nonadherence) of the patient's increased INR were ruled out. Using the Horn Drug Interaction Probability Scale, our patient's warfarinmarijuana interaction appeared to be probable.

CONCLUSIONS: To our knowledge, there have been no other reported cases of warfarin-marijuana interaction. While more clinical reports would be useful to confirm this interaction, clinicians should be aware of its probability so as to manage patients appropriately.
