Yeh to be honest coke is one of the most boring drugs I know of. I use to use it back in the day when I was young and it was more or less a novelty but in the grand scheme of things it doesn't do much thats really addictive.
It just numbs your body, chills you out, but doesn't exactly "relax" you. Its weird cause I'd snort it and feel calm, but my heart would race and later on in the high I'd get paranoid. So it had just as many things I didn't like about as things I did like about it. And things I liked about it weren't that many.
I have one of the most addictive personalities in the world and never got hooked on coke. Plus compared to other drugs it doesn't have a real strong rebound affect. Sure you'll feel tired and anxious but it was never really severe like opiates or speed.
Now that ONLY is considering snortable coke. Freebase smokeable coke is another story. I tried that once and instantly was hooked. All it takes is a bit of baking soda, heat, foil and a tube and you will get high as a kite and feel great. That could def bring all the compulsive traits of a personality out. Injectable coke I'd imagine also feels completely different and has a rush, but as long as you're just snorting it you might as well enjoy it.
A problem I use to have with coke was I'd drink usually right after snorting it, and the alcohol can kill the high. I mean you'll be awake and still feel it, but as elusive as a coke high can sometimes feel alcohol almost makes it dissappear imo. And this is mostly recreational doses I never really got a crazy tolerance or did tons at a time so to each his own I suppose.
