Unlike food, nicotine is not a necessity. Also calorie intake alone doesn't determine weight gain or loss. The problem of obesity is much more complex.

Governments try to address this problem through education and regulation of food. There are drugs available now to help control obesity and they're very popular, so people obviously want to avoid the condition.

I don't know why you think people should have a right to take highly addictive drugs that result in premature death. Contrary to smoker's claims, cigarettes are pure addiction and provide no benefits whatsoever to the smoker.
