Some smokers or more serious junkies may reveal a different kind of freedom – their addiction to the drug as freedom from life! as freedom from health!, when life and health don’t have a meaning worthy enough to be lived and support a person in existence. Such people may be immature – but also it is true that at least some of them, (or all of them as long as they keep smoking), don’t have the survival-instinct of a beast, they are not willing to live at all costs. This is a suicidal activity, more or less conscious as such. It is not the best a man can do, far from it, yet it is better than mere survival.
This is also the reason why only rarely one can convince youngsters to stop damaging their health with cigarettes. Young persons, if they are young, are in search for meaning, not for health. They have all the health of the world! We can not make them care for their future health, when they don't know what to do with the health they already have!
