No dont stop taking your prozac. From what I've read. Smoking on prozac can cause hypomania and it can increase or decrease the levels of prozac or any head head med your taking. I would call and ask your pharmacist if it's safe. They are super helpful and then you don't have to have a uncomfortable convo with your doctor. Marijuana affects everyone differently. Start with a super small amount at first. I used to smoke on the daily but, in the past few years it's become so strong that I can't even smoke a little without panicking for hours. It's become an unpleasant experience for me so I quit. I personally wouldn't recommend it unless you're able to purchase a low thc strain.
