I don't think I'm immune, but I am certain I'm not addicted to nicotine despite having smoked dozens of times, and I think that's a story worth sharing, even if you don't.
Sorry I don't have a better analogy, but it's like coming home from a tour in the military, and telling everybody "hey guys, war is perfectly safe, look at me I'm still alive!" — I'm really happy for you, but others are going to listen to your "story", follow your example, and have drastically worse results.
I think it's more interesting learning from those that went through hell, not the reckless lucky ones that managed to stay unscathed and think they're hot shit. Luck ain't a skill nor wisdom.
I know these are strong words for the matter at hand, but there must be an ex smoker or three that know exactly what I'm talking about.
There is a little bit of “smarter” in there but really, i’m just not an addict. Some people are, some aren’t. I know several people who have rarely smoked and never had problems with addiction.
I think part of it is some people are more susceptible to addiction than others and another part is that the “just one” is BS, you can learn to not let it happen to you without total abstinence.
Smoking one or 100 cigarettes doesn't guarantee addiction, it's a Russian roulette. If you haven't heard BANG yet, doesn't mean there's no ammo in the chamber.
You're not better or smarter than smokers. You just were more lucky.
