Yeah I did some experiments on myself.
- Whenever I stopped smoking, the diahreah went away usually a day after(the usual time it takes for digestive system to finish
- Another of my friends told me it was because I take too much smoke into my stomache on a toke and ever since then I have been severly watching how I toke
- I checked to see if I have tainted weed by getting weed from a LOT of different dealers (even from quebec!) And the same thing happens
- I tried eating different things (rarly drink soda) and even tried eating nothing when I get the munchies, same thing happens

Iunno maybe I'm allergic to it?!?!?!!!
