We are getting conflicting information. Everything I read says smoking is bad for crohns. However my Granddaughters Dr. said recent studies have found that smoking MAY help crohns. She was ready to quit until this bit of information came her way. Now I am having a hard time convincing her to quit. I can't find any research to support what her Dr. said. Has anyone with crohns quit smoking and discovered it helped? Or has anyone found documentation to support the information that smoking helps?
