Is it safe to use cannabis with antidepressants?
Research-Based Answer
Cannabis interactions with antidepressants are complex and vary by drug class. SSRIs/SNRIs: CBD inhibits CYP2D6 and CYP3A4, which metabolize many SSRIs (fluoxetine, paroxetine) and SNRIs. This can increase antidepressant blood levels and side effects. THC may also interact pharmacodynamically, potentially worsening anxiety or triggering mania in susceptible individuals. MAOIs: Potentially dangerous combination — both cannabis and MAOIs affect serotonin systems; risk of serotonin syndrome is theoretical but not well-characterized. TCAs: CBD inhibits CYP2D6, which metabolizes tricyclics; elevated TCA levels increase cardiac arrhythmia risk. Bupropion: Both THC and bupropion lower seizure threshold; combination may increase seizure risk. The safest approach is to consult a prescribing physician before combining cannabis with any antidepressant.
