I remember when I was younger on the weekends a group of us would buy cocaine. For most of the group we only did it on weekends, had good jobs, maintained a normal lifestyle during the workweek. A few in the group became addicted to the point where they lost their cars, girlfriends, job. Sold anything and everything they could to obtain cocaine. Most of us grew out of it, but a few went downhill. All of us for the most part as far as I know were equal in every way in life. We grew up together, played together went to school together, and hung out together. All of us came from middle class families. There were 8 of us all together. 5 of us no longer use cocaine, 3 of us use pot recreationally. I guess my question is "What causes some people to make cocaine a lifestyle and some of us don’t"? Is there a genetic link to an addictive personality. I have observed some people use cocaine and walk away from more while others immediately wanted more.
