Anti-anxiety Medications and cannabis (marijuana, THC)
As cannabis becomes legal or decriminalised in more jurisdictions, the practical question of combining it with prescription medication comes up regularly. Anti-anxiety Medications (Anti-anxiety Medications) and cannabis share several pharmacological pathways, and the combination at 0.5mg, 1mg, 2mg, 5mg, 7.5mg is not automatically benign even where both are legal.
How cannabis affects Anti-anxiety Medications
THC and other cannabinoids are metabolised partly by hepatic CYP enzymes, including CYP3A4 — the same pathway used by many Anti-anxiety Medications medications. Frequent cannabis use can shift the metabolism of Alprazolam, Buspirone, Clonazepam, Lorazepam mildly. THC also has cardiovascular effects (increased heart rate, blood pressure changes) and central nervous system effects that can stack with Anti-anxiety Medications's side-effect profile.
Practical guidance
Occasional moderate cannabis use is unlikely to cause clinically meaningful problems for most adults on Anti-anxiety Medications at 0.5mg, 1mg, 2mg, 5mg, 7.5mg. Heavy daily use, edibles with high THC content, or cannabis combined with alcohol substantially raise the risk of dizziness, hypotension, impaired judgement and amplified side effects from Alprazolam, Buspirone, Clonazepam, Lorazepam. According to the prescribing information, the full list of recreational substances should be disclosed to the prescriber.
Frequently asked questions
Can I use cannabis while taking Anti-anxiety Medications? ▾
For most adults at 0.5mg, 1mg, 2mg, 5mg, 7.5mg, occasional moderate cannabis is tolerated, but heavy daily use is not advised because of metabolic and additive cardiovascular effects with Alprazolam, Buspirone, Clonazepam, Lorazepam. The safe practice is to mention it to the prescriber.
Does CBD interact with Anti-anxiety Medications? ▾
CBD inhibits several CYP enzymes including CYP3A4, which can raise plasma levels of medications that go through that pathway. For Anti-anxiety Medications specifically, this depends on whether Alprazolam, Buspirone, Clonazepam, Lorazepam uses CYP3A4. Daily high-dose CBD products warrant a pharmacist check.
