I don't know anyone who has lamented to me that they simply could not find the drug they were looking for. Think about that for a while.
All the interdiction efforts have gone for naught. Sure they seize a good deal of drugs, they arrest lots of people. Somehow though the drugs continue to come in. They come in at a cost to society in violence, in corruption of those who are charged with interdiction, moral corruption as well. Casual users find a certain disdain for the authority that tells them so many lies about the drugs they currently take, ( a well documented effect of the 55mph speed laws) seasoned abusers have no respect whatsoever for authority.
How far would the DEA budget go when applied to treatment rather than interdiction? What is the cost of incarceration? How much does it cost to rehabilitate? Those are mathematical questions. How much of our liberty has ben usurped in the name of drug enforcement? Legitimate
as well as bogus property seizure is but one example.
Peace Officers have become Law Enforcement Officers, the para military wing of public service. This new distinction thrives on intimidation and physical force, worried more about demanding respect rather than earning respect. As individuals I have met narry a bad cop but as a group they have become arrogant prigs, not deserving of my respect ( I make a point of treating cops as individuals ). They train as soldiers, think as soldiers, dress as soldiers, whenever possible recruit from the military. Then they treat us as enemy non-combatants.
We have absolutely zero experience with decrimanalizing drugs. We have plenty of experience with making them criminal, and how's that working out? Supporting the war on drugs is about as stupid as supporting the war on poverty. Both programs are abject failures. A new approach is warranted.
