Sorry to go off topic, I'm a bassist too. Did you get yourself a new amp? What did you choose? Very on point story.
Ok, my crack experience... Too high, then too low, carpet shopping for more while silently hating everyone else around me, believing they shorted me, which they probably did. The biggest feind in the group gets the most. It's not a friendly drug, it's an every five minutes fight to stay high drug. You never win the fight, you loose terribly.
It's simply not worth trying. Not b/c your certain to get addicted, but b/c it's a shifty, shitty drug. Buy some good weed instead and enjoy a high that is fun, not compulsive. Or a couple of good beers...
You haven't known compulsively at all until you mainline or smoke cocaine base. Heroin users (been one) jones b/c of physical and psychological need. Crack users often can't explain why they need more. They just do when in fact they will be physically fine without it. Consider that OK, you've been the H route. This is much, much more severe in its mental head fuck.
