I can answer this, I've been on Ozempic in the past and prescribed Mounjaro (Tirzepatide) currently (month 3).
I've had a medical cannabis prescription for many years and vaporise up to 3g a day which is quite a bit. It definitely interferes with my cravings for food, as you know the common 'munchies' effect, making me eat when I'm not really hungry or binge snacks.
I gave up on Semaglutide (Ozempic) after a few months, but Tirzepatide is working a lot more effectively and has been better.
Cannabis also helps a lot with the nausea side effect for me which can be particularly bad the first few days going up a dosage every month. It takes six months to titrate from the starter dose to full strength, if necessary.
Also the downside a lot of people don't talk about is that most people need to be on these drugs for life. They also aren't cheap.
