Can you tell me if there are benefits for smoking cigarettes?

Only in peoples mind: There is no safe level of tobacco. Smoking is linked to such a long list of medical problems - the space here is too short. However, it has a powerful effect on how people think, because that cigarette wants you to keep smoking. People will feel more calm, more awake, less anxious, less sad. Mostly because if you don't smoke, you will feel worse. So the benefits are only perceived, not real.
