Hi Justice, I have a son that's 30. We found out about six months ago, he has Crohn's Disease. The Dr. said he's had it for about five years. We thought he was a healthy 30 year old. It is so bad he my need to have part of his large intestant removed. The Dr. said, he needs to quite smoking. He has smoked for twelve years. The Dr. gave him a proscription called, Chantix. He said instead of putting nicotine in his system it goes to the part of the brain where he has cravings and ,stops them. He said there has been a lot of success. My son took it for just over two weeks and said the craving had been stopped for several days. Maybe you could give it a try. Good luck
