Well, I picked up smoking from a girlfriend in college and we used to smoke all the time. Like ten cigs a day for a year and a half. Real bad, right?
Well, one day, I decided "Meh. I'll just stop" and I did. Not because of any reason. I just chose not to.
Now cigarettes are way addictive but I just chose to stop. More addictive than Benzos and shit and I just stopped cold turkey without any other reason.
Many of my friends struggled with quitting but eventually did. But I did it way easy. It's unlikely that I'm some super outlier, but clearly I'm some near the right edge of the bell curve in ease of exiting cigarette dependence.
That makes me think there are other outliers. This guy must be a heroin outlier. And considering the dependence inducing strength of that drug, he must be a far outlier.
