You will use the 'they get hold of them anyway' argument maybe?
Well that is for sure one factor. An addict is an addict. Just trying it once they will go searching. But the thing currently is... which most people don't know. Doctors are the biggest drug dealers in the US of A. Doctors get you hooked onto heroin before you start searching for heroin. Doctors get you hooked onto uppers before you find meth. This is bc drug addicts doctor shop. When i would do it... i had 5 doctors that would give me: 120 norcos 120 vicodin. 60 opana. and 40 xanax. All 5 of them. Norcos, vicodin, xanax sell for 4 dollars a pill... discount to 3 a pill if you buy a lot. Opana would sell for 40 dollars each. Times 5 doctors... you can do the math.
This is happening bc yeah... good doctors won't prescribe you more bc they can see that you've picked up before. Corrupt doctors don't care. Plus, you would use insurance once to buy them... then buy the rest with cash. And finding doctors that will do this isn't hard either. You can to run down places or in my case ... a lot of foreign doctors, asian, middle eastern, would do it. You just go to them and ask for all of the above. If they said no. You walk out. If they said yes... you just found yourself another gold mine.
So this is how it's happening right now. But if we legalize it and regulate it. We can figure out something that won't allow people to get that many. I thought of a "punch card" or something like that wold work best. Where you get one punch... then you can't get more for a month. Or a credit card specific only to buy them with. You swipe once a month... then you can't get anymore till the next month. Having it as it is right now... it's not working.
