How much do you give out then? At some point you'll be giving someone a dose so high they are guaranteed to die. Obviously no one can do that because of legal justifications. However now you have to set an arbitrary limit to what someone can receive. The user may not agree with this amount and will seek to acquire more. Thereby resorting to the same tactics as before it was given away. I don't think it's as simple as you want it to be.
