[The Straight Story]

46. I'd rather trade health for freedom than freedom for health

Health Benefits:

Digestive system
Risk of ulcerative colitis has been frequently shown to be reduced by smokers on a dose-dependent basis; the effect is eliminated if the individual stops smoking.[5][6]
Smokers are less often affected by aphthous ulcer.[7]

Cardiovascular system
Kaposi's sarcoma[8]

Reproductive/breasts
breast cancer among women carrying the very high risk BRCA gene[9]
Pre-eclampsia[10]
Smoking can also reduce rates of uterine fibroids.[11][12] This may be due to estrogen inhibition, as opposed to general inhibition of inflammation.
The risk of endometriosis has been reported to be reduced in smokers.[13]

General
atopic disorders such as allergic asthma[14]

Neurologic
Smoking has been consistently found to be a protective factor on epidemiological studies for Parkinson's disease. The basis for such effect is not known but possibilities include an effect of nicotine as dopamine stimulant.[15]
The majority (80% in Australia as of 2001, 85% in the US as of 2007) of schizophrenics smoke, apparently to self-medicate.[16] Nicotine appears to be an effective antipsychotic, and work is underway to develop antipsychotic drugs based on nicotine without the ill effects of smoking or of nicotine itself.[17]
