Cannabis & medication interactions: FAQ

Common questions about combining cannabis with prescriptions.

Can I use cannabis with my prescription medications?
Sometimes — but not always safely. Cannabis can change how certain medications are processed by the body, which may make them stronger or weaker than intended. The safest approach is to run the free Med Check for a quick read on your medication classes, then confirm with your physician or pharmacist before making any changes.
Does cannabis interact with blood thinners like warfarin?
This is one of the more closely watched combinations. Cannabis may affect how blood thinners such as warfarin work, which is why monitoring matters. If you take a blood thinner, treat cannabis as something to discuss with your prescriber rather than start on your own.
Can I take cannabis with antidepressants or anti-anxiety medication?
Many people do, but there are real considerations. Combining cannabis with antidepressants, anti-anxiety meds, or sedatives can add to drowsiness and other effects. A pharmacist can help you understand your specific combination — the Med Check is a good first step.
How does CBD affect how my medications work?
CBD can influence the same liver enzymes that break down many common drugs — a bit like the way grapefruit interacts with certain prescriptions. That can shift medication levels in either direction, so it’s worth checking before adding a CBD product to your routine.
Is the Med Check medical advice?
No. It’s a free educational screening tool to help you spot where a closer look may be warranted. It doesn’t replace your doctor or pharmacist. For a personalized review of your full medication list, book a pharmacist consult.
