Answer
The major effect of smoking tobacco, or any other use of it, is cancer. Tobacco use contributes to many cancers, notably lung cancer but including cancer of the gums, tongue, stomach, and bladder. As the number of smokers in the US has plunged over the years, so has the rate of people getting lung cancer. Once the number one killer cancer, lung cancer has now yielded that "honor." Smoking tobacco can also cause lung cancer in non-smokers and can provoke asthma outbreaks in non-smokers.
