The high is wonderful for those two to three minutes and the energy/endorphins are damn near magical if it isn't a common occurrence for you.
However, the cost and the quality greatly affects the experience and to get good shyt, you gotta pay too damned much so it makes it not worth it in the long haul unless you really like (addicted) to it.
My few dalliances with it happened to be in this small time frame where I met and befriended an actual pusher who had quality shyt and I did it for free since my friend who turned into a cokehead that year was buying a solid amount from him.
Unless I'm with a broad who's gonna do a like or two and then look to have it away with me, I tend to stay away from coke related shyt cause it makes idiots really show themselves and that's never a good look around Coke.
