Smoking is not a good habit, either for the individual smoker or for society as a whole.
First of all, smoking is not healthy, leading to more deaths than any other preventable cause. Smokers live about 14 years less than normal people. Babies whose mothers smoked during pregnancy are often born with defects. Smoking also causes cancer, damages organs, and weakens the immune system.
In addition, smoking can also harm those nearby, in terms of second-hand smoke. Health care expenses raised by the consumption of tobacco creates a social cost on everyone as well.
The main chemical in tobacco, nicotine, is addictive, so quitting can be hard. It would have been best to never started smoking at all. Still, for smokers, quitting is still the wisest choice. Excise taxes are imposed on tobacco, and employment and health care favor non-smokers, precisely because smoking is bad for everyone.
