/turn on old man syndrome
To the OP's idea. I would recommend being very careful in the implementation of drugs or substances other than healing herbs(homeopathy based)... I mean, VERY careful. The adults who play the game have already reached their decisions regarding such things, sometimes to their peril, up to them. BUT, the younger folks who play the game should never get mixed messages as to the perils. Simulated addiction and real addiction are very, very different monsters. Dangerous ground to tread and shouldn't be taken lightly at all.
