He has a somewhat good idea. I would actually prefer to legalize drugs, but having users register and be put off limits for some jobs might work, although you would still have illegal users and the war on drugs might continue unabated in this case. Take the money out of drugs and you will end the problems caused by gangs, also we can then disband our swat teams, which need to be done away with immediately, if not sooner.
The users, registered or not, are already banned from jobs require drug tests.
I do think the WOD needs to be greatly changed or mostly done away with, I just don't care for this fella's prescription.
