My son who is 21 smokes cigarettes and I hate it, I have been on him to quit, I mean he has asthma for crying out loud! His best buddy has crohn's disease and he also smokes cigarettes. I asked him once if he thought he should quit due to the crohn's and he said it did not bother him at all. He was diagnosed with crohns when he was 16 or 17. He is also now 21 years old. He also told me he does Not take any medications at all for his crohns and he is doing well. He attributed his well being to smoking cannabis. Now obviously it is illegal over here in this state but everyone is doing it from what my son says! Not that I would ever encourage anyone to smoke cannabis, especially if it is illegal, but I know they have passed it for medical use in some states. If you live in one of those states, then maybe that would be a better option instead of cigarettes. But still, it cant be good for the lungs. Taking it in an oil or in food would be better..."
Ihurt, while googling smoking and crohn's, I came across this about smoking pot and crohn's:
O'Shaughnessy's, a scientific journal, published a study in its Autumn 2005 issue titled "Cannabis Alleviates Symptoms of Crohn's Disease," by Jeff Hergenrather, MD, that found:
"[Crohn's] patients described marked improvements with the use of cannabis.
Beneficial effects were reported for appetite, pain, nausea, vomiting, fatigue, activity, and depression. Patients also reported that cannabis use resulted in weight gain, fewer stools per day and fewer flare-ups of less severity...
Cannabis-using Crohn's patients not only report significant relief of their symptoms, they are also able to reduce the amount of immunosuppressive medications that have been a mainstay of conventional treatment...
Crohn's disease is so debilitating and life-threatening and so difficult to manage with conventional medications it is very encouraging to find that cannabis is proving to be an effective treatment for it right now."
