Cheech I'm talking strictly as a substance they're the same thing. Mixing agents, etc can affect the purity therefore the intensity of the effect, but that don't make it a whole other drug.
Freebase when done right is basically a pure version of "crack." This is the only way I can explain it. Crack is just the result of a sloppy process of turning coke into crack, without purifying it.

Yeah to coke and not to crack, never done it in my life I don't plan to, but lol that sounds like a great idea, thank god we don't have crack whores here, only a few H ones.
