I think the actual crime here is that we waste so much money on Interdiction, Arrest, Prosecution and Detention of relatively minor drug offenders. While I agree that as long as there are laws "against" a substance, there should be some sort of penalty, I think the way we have gone about it is wrong.
The crimes that marijuana allegedly led to included; rape, white slavery, murder, theft/robbery, riots and other items that did not bear any resemblance to reality then or now. Anslinger & Herst manipulated the facts portray marijuana in the most negative light possible.
I believe it is time for States to begin to assert their Rights over Federal edicts but, as the author pointed out, it will be an expensive proposition. It IS time to do it.
