True, nicotine is addictive, habit forming and smells. No argument but unlike other drugs it doesnt alter your personality and you dont get stoned. No one ever went to jail saying rhey didnt mean to beat their kids but they smoked too many cigarettes and couldnt help it.
Maybe smoking doesn’t alter your personality, I won’t argue that one way or the other but, as a former smoker who is the son of a smoker and grew up in an environment where teenagers were allowed to bring cigarettes to high school if their parents signed a permission slip for them I can certainly tell you that DEPRIVING an addicted smoker of nicotine can CERTAINLY change his or her personality for the worse very quickly and it can be amazing to see to what lengths a person will go to get a cigarette.
I could tell you about my first cousin, who in his youth had been a very athletic, classicly handsome young man with an absolutely brilliant mind and three times the energy of anyone around him who developed emphysema but kept on smoking until he died in a nursing home in his early sixties. At one point he burned his face trying to smoke a cigarette while wearing an oxygen canula in a hospital room. He was five or six years older than I and I had really admired him when I was a young boy. Remembering all that he went through is one of the few things that can cause my eyes to water now at age 69.
If I made a long list and it WOULD be a long one, of all the stupid things I have done in 69 years, smoking cigarettes would be near the top of the list.
