My father did the same thing. He used to smoke a pack a day and the day that I was born he quit and never touched it again, and then when I was old enough to understand cigarettes, he taught me to never start smoking and I never have.
And then one day they were awesome and relaxing.
Now recreational marijuana (ideally through bong) is way way more appealing than dumb tobacco cigarettes which do nothing, had it during my teenage years and also during my 20s on different ocassions with colleagues/friends (one of them used it during cancer treatment) and I can see myself having some even now in 40s if I could buy it legally.
