So what is your solution?Legalize, tax, and regulate....starting with pot. Allow harder drugs to be dispensed via prescription, like they used to do in the UK. Apply the lessons we learn from pot legalization to other drugs, gradually.
Will this cause new problems? Yes, of course. But right now there are only three options:
1) Effectively enforce the WoSD. This would require sharp abridgement of our civil rights. How many of your rights are you willing to give up to ensure that your neighbor is not, in the privacy of his home, using narcotics? My answer is Zero.
2) Continue our current half-ast level of enforcement. Allow it to continue to enrich the most ruthless criminals in the black market, corrupt law enforcement, and generally degrade public respect for the law. In other words, Prohibition Part II: Let's Try It With Legalized Theft. Unacceptable.
3) Gradually legalize drugs. This will produce its own problems, much like the end of Prohibition did. But IMO these problems will be less intense than the ones we face now.
