I've done some research and according to some sites, if you don't y'know, get the munchies and eat everything in your kitchen, smoking weed will actually lower your blood sugar, so i was wondering since i'm diabetic, does smoking weed help me control my blood sugar? I've been smoking since high school, and i've definitely noticed my Hemoglobin A1C levels going down.
I've never heard of weed's effects on blood sugar or diabetes in particular, but it's safe to say that it's very unlikely to be dangerous in reasonable amounts. The biggest risk for diabetics I can see would be, like you said, getting the munchies and eating loads of junk food and sweets. As long as it's healthy food and you don't neglect to monitor your blood sugar, you should be fine.
