Which chems are addictive?

Question

Specifically, I'm wondering about Turbo, Cateye and Hydra. Are any of them addictive? If so, what's the chance of getting addicted?

I've been holding onto these chems, but selling the ones I'm used to (Buffout, Med-X, Psycho, etc.), in case they could be useful without "hooking" me. Am I misguided? If so, am I misguided because (if I want to avoid addiction) I should sell them, or am I misguided because (if they're not addictive) I should be using them when needed?
