• Cigarettes aren’t the best treatment for anything and the potential benefits never outweigh the harm but cigarette smoking treats some types of ulcers, colitis, and a few other lower GI issues. It may also prevent or reduce the severity of Parkinson’s Disease, Alzheimer’s dementia, endometrium cancer, uterine fibrosis, and endometriosis. It also negatively correlates with DVT and may make you more likely to survive if you have a heart attack.
