Hmm this needs to be a "What's Better: IV Coke or IV Meth".
That said, it depends. Meth has more "purpose" to it, it's something I would do late at night if my friend took acid or meth himself or just woke up. It keeps me up to enjoi what I normally would be too tired, and it has some euphoria and fun to it.
Coke on the other hand, I would do to help me sleep.
Still, I'm not sure which I would prefer. Their both things I would do just to do something, to kill time, kind of thing. I just spend on H if anything, but either is easily available and offered I sometimes dish out a little bit just for a change of pace.
I guess I would prefer IV meth because you can stay up a while on it, though it's hard to get sleep. You need some strong shit to put you out after that stuff.
However that coke rush is one hell of a thing. Meth barely has a rush compared to coke. Then again, I don't care too much about rush. It's about the high.
