Smoking doesn't affect all of the people the same way. Your system may be better able to handle the toxic load than other peoples. But statistics are clear. On average smokers have greater health problems and die earlier than do non-smokers. That doesn't mean every smoker will develop health problems, anymore than it means every non-smoker will be healthy.
Die EARLIER? Then why is Medicaid offering a smoking cessation course? That IS what this thread is about, or didn't you read it?
Smoking STILL beats being a crack-head any day!
