I totally agree. I was a weekend user for a period of time, when I had free access to excellent stuff. I had no problem quitting, but then I am also able to smoke cigarettes on weekends and not get hooked.
To a certain point, the more cocaine you do, the more reinforcing it becomes (i.e. you want to keep doing more and more) but the first time I ever had a nasty coke comedown I learned my lesson about how totally shitty you feel after doing too much. I moderated my usage after that and kept a supply of benzos handy.
And I still don't get why people think meth is better than coke. I realize I'm the odd one out and I have extremely limited experience with meth compared with coke... but I find coke strongly euphoric and find it puts me into a fabulous mood, whereas with meth I just got anxious and paranoid.
I have never smoked/freebased or injected coke, but I would imagine it's a lot more addictive than insufflating it. If you are concerned about addiction, get a small amount of coke with a friend or two, finish the bag in one night, and don't keep any around the house.
