Not really a "zealot" by any means. I would even suggest that we shouldn't put the blame on the users as much as the traffickers. It's all about supply and demand. Without a supply, the junkies can demand all they want . . . they just ain't getting any. : )
You are hoplessly nieve. Also, you clearly do not understand econmics.
If there is demand, then there will be supply. Where supply and demand meet, you get price. If you artificially limit the suppy, the price goes up. That means ever MORE profit for the supplier. Which means ever more people willing to supply.
One question you should be asking yourself is: "Has the relative price of an illegal drug (pick one)gone up as a result of increased efforts to undermine the suppy?"
The answer is no. Next question: Why not?
You are being overly simplistic with the "users" and "traffickers" distinction. Traffickers are not always drug cartel smugglers. Most "traffickers" are actually users that pick up some for their friends.
Traffickers are also users that keep a larger personal stash to cut down on the number of transactions. Since the legal definition of "personal use amount" is often very small, its very easy to get bumped up into the "possession with intent to sell" category.
I would wager that you actually know some of these "traffickers" and don't even realize it. Your children or their friends may actually be "traffickers" and you'd never know about it until they got a public hanging.
