This is like a test tube example of the failure of the Drug War. We banned the drugs. This created a black market. Prices soar, and there is a seemingly endless number of people willing to try and get drugs to those with the money to pay. If you can't even keep the stuff out of prisons, what makes you think Drug Prohibition is keeping drugs off the streets? It quite simply isn't. It is just a big-fucking waste of money, not to mention the denial of the rights of millions of americans who are otherwise law-abiding the right to their own body.
