This is the most common thing you hear from smokers about the benefits of smoking. This is because cigarettes create a myriad of conditions that help the body deal with anxiety,stress, and depression. But there are others that you ever hear:
1. Smoking lowers risk of knee-replacement surgery
While smokers might go broke buying a pack of cigarettes,they can at least save money by avoiding knee-replacement surgery. Surprising results from a new study have revealed that men who smoke had less risk of undergoing total jointreplacement surgery than those who never smoked. 

2. Smoking lowers risk of Parkinson's disease
The most recent, well-conducted study was published in a March 2010 issue of thejournal Neurology. Far from determining a cause for the protective effect, these researchers found that the number of years spent smoking, more so than the number of cigarettessmoked daily, mattered more for a stronger protective effect.

3. Smoking lowers risk of obesity
Smoking — and, in particular, the nicotine in tobacco smoke — is an appetitesuppressant. This has been known for centuries, dating back to indigenous cultures in America in the pre-Columbus era. Tobacco companies caught on by the 1920s and began targeting womenwith the lure that smoking would make them thinner. 

4. Smoking lowers risk of death after some heart attacks
there's a catch, though. The reason why smokers have heartattacks is that smoke scars the arteries, allowing fat and plaque to build up in the first place. So, one theory as to why smokers do better than non-smokers after such therapies isthat they are younger, experiencing their first heart attack approximately 10 years before the non-smoker.
