once all hard drug use became legal, everyone but hard drug users would be robbed and hunted into extinction. The easy targets like pawn shop owners would be the first to go. Rick Harris doesn't even have to phone a friend who is an expert in this shit...he already knows it. Through the process of attrition, weed users will become obsolete. Eventually it will just be meth, coke, and heroin users, and coke users will be hunted for their bling. Hence it's just going to be cockroaches, meth and heroin users, and keith Richards all duking it out for survival in some sort of post apocalyptic reality television zombie scenario.
