My 2 cents
I say if he really wants to try it, try it CAREFULLY.
Ive had the same curiosity with meth, coke crack and smack. Ive tried all of them, and honestly, I have no desire to return to them. Im a curious person, albeit prone to addiction, but for me, quenching that curiosity is all I needed. If this is the same for you, proceed with caution, but if YOU think this is one fantasy that cant be done, avoid it.
You know the best answer man, none of us do.
