Cannabis

· Severity: Major

· Notes for Consumers: Discuss cannabis use with your care team. The effects of cannabis may be altered if used with your medication.

· Notes for Professionals: Advise patients to avoid cannabis use during rifampin treatment. Concomitant use may decrease the concentration of some cannabinoids and alter their effects. The cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are CYP3A substrates and rifampin is a strong CYP3A inducer. Concomitant use of a cannabinoid product containing THC and CBD at an approximate 1:1 ratio with rifampin decreased THC, 11-OH-THC, and CBD peak exposures by 36%, 87%, and 52% respectively.
