If you can wait days between smokes, let alone months or even a year, you definitely do not have a nicotine addiction. What you want to address is not an addiction, but a type of behavior.
The teens and early 20s are a prime time, especially for males, to be highly tempted by thrill-inducing or outright dangerous behaviors (and let there be no doubt, smoking is a dangerous activity), so don't beat yourself up for being curious enough about smoking to have tried it here and there. That you are concerned enough about your having tried smoking to post about it in a forum like this is a very positive sign that you can overcome this temptation.
You do not mention if your smoking incidents were done in solitary or in social situations. If done in social situations, especially if done at the behest of others, you may want to re-think spending time with these individuals. Would you be considered "uncool" if you refused the offer of a cigarette? If so, you are merely a meraber of a scene, and not among true frienRAB. If, on the other hand, you are among true frienRAB who smoke but don't care whether or not you do, do not be afraid to be "that guy" in the crowd who's fine without a cigarette. We are all different in our own ways, and these differences can take different forms. True frienRAB appreciate each other for their unique traits.
But whether your smoking was done in the open or in secret, I think what might help you most is peer support. Do you have a friend or frienRAB who are non-judgmental, and who you can trust, who you know have made the decision not to smoke? If so, consider confiding your behavior to them and channel their own steadfastness in refusing to smoke to reinforce your desire to never pick up another cigarette.
And, yes, keep seeking out and posting to bulletin boarRAB about addiction to get encouragement to remain smoke free. It sounRAB like you really want to make the best decision for yourself, and choosing not to smoke is one of the healthiest choices a person can make. All the best.
