Yes, I think it would be critical knowledge for people requiring opiate treatment (I hate the damn things, I've lost two friends and a family member to addiction and abuse of opiates). My nephew is on the edge of dying from opiates too, in a downward spiral without much hope right now.
I have read much about IBS and Celiac treatments with MM. There is so much conflicting information posted all over the Interent concerning MJ and side effects. My take away from the reading would have been that is does help regulate bowel regularity and stool consistency. I have a relative with Celiac disease, which is a genetic autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. She might benefit from MM, but she is way to classy to take the marijuana stuff! God love her ... no one else does it seems!
I can't say that smoking cannabis has had much effect on my gut habits in my lifetime. I usually only chew on a raw bud or two when smoking isn't an option, and two recent experiences with CCO (lab rat didn't die or OD). When I do bud munch, I feel a difference in my stomach and large intestines after an hour or so, much less grumbling and gurgling (Gall Bladder removed 30 years ago).
What a crappy subject Sue... sorry you know someone had to be immature.
