My parents were against my smoking even though my dad smoked a pipe. I respected the rule that I could not smoke cigarettes at home.
At 18 I married a heavy smoker and went downhill to serious addiction.
My son began to smoke cigarettes at 16. I did not nag or discourage him. I knew that he wasn't able to afford to spend much on them. At 18 he gave up because he had fallen for (and later married) a girl who is an avid non smoker.
The power of love
- hope that it will happen that way too with your son (fingers crossed)
