I'll vote for just don't fucking try it. Yes, I have done it (more than I care to admit) and it's shit. The high is immediate and intense, but the comedown is (basically) immediate and even more intense.
If you insist on `trying something new` and doing it, be prepared for the comedown, and the intense desire you will feel from some power that seems outside of you, to do MORE at any cost. It's fucking insidious. I would say be prepared for the comedown with benzos and alcohol (lots.) For harm reduction, though, using crack then taking benzos and alcohol is NOT safe and nobody should do it. So you see the situation is fucked and desperate. Like you will be coming down from crack.
If you want to try something new and waste money, sky-dive instead. It's very similar. You get really high, do something life-threatening, it's over way to quick and you will only want more. At least skydiving is looked at as relatively sane compared to crack.
Seriously, fucking don't. This is one of those cases where curiosity is best left unsatisfied. 5 minutes of `wow` isn't worth hours of `oh fuck I feel like shit and would consider sucking a homeless persons toes/cock/feces for more crack.` Even meth is a better choice than crack.
