How common is NOT getting addicted to smoking, despite trying real hard?

I have this weird trait. I don't get addicted to smoking. And I've tried hard.

A couple of years ago I smoked for slightly over a year. My cancersticks of choice were a variety of Camels that had the highest nicotine content of any cigarettes sold around here. Sometimes I smoked an entire pack each day.

Then I suddenly discovered that I had run out of cigarettes *a week earlier* and hadn't even noticed. It's not that I was doing anything special. Mostly just sitting in my apartment, playing games and doing some work on the computer occasionally.

I went from smoking a pack a day to not smoking and didn't even notice it. And yes, I inhaled deeply.

Recently I fell on some hard times and decided to take up smoking again. This time I rolled my own cigarettes, often without filters. Did so for about two months. Inhaled deeply. Smoked several per day and these were really strong ones. Often the first few lungfuls would make me weak at the knees.

A few days ago I got my shit sorted out and felt like I didn't really want to smoke anymore. So I've been smoke free for about three days now and the only thing I miss is not having something to do while walking.

I've never been addicted to alcohol. There was an intense period during university times when I took caffeine pills and then felt like shit for a week or two when I stopped taking them. Haven't been addicted to computer games either -- usually I just play intensely for a day or two and then I never want to see the game again.

Also, I probably take more risks than the average person. I'm an entrepreneur and have founded a couple of non-profits. I haven't had what you might call "a stable job" in years. Those get boring fast.

**Anyway, my question is:** How common is it for people NOT to get addicted to things like smoking? Is this genetic and is it correlated with anything? Is it a symptom of anything?

**TLDR:** I can't get addicted to smoking. What's up with me?

Probably some sort of normal distribution thing - after all, one can get SEVERELY addicted to cigarettes after a short time - perhaps you're just on the other end of the addiction spectrum. 

Please don't test this theory with heroin next week.
