I have no idea where you're going with your post. You jump all over the place. Legalization would mean disbanding pharmacies? Costs to "society"? Smuggling of legal products? Addicts killing people over a cheap, legal product? "Free" drugs paid for by the public? Where did you come up with all of this? Until you demonstrate, using logic and reason, how any of these catastrophes would occur as a result of not putting people into cages for using drugs, I'll leave you alone to continue your acid trip.
That's called "hitting all bases". I've obviously given this much more thought than you have. You haven't thought more than one move ahead. Your entire plan appears to be "legalize drugs man". I've heard the argument for 20 years from people that HAVE given it complete thought and the ONLY ones that make sense are the people who take a Darwin approach. Kill the drugies fast and have less trouble. Although that makes sense to me, it is a bit less caring that my conscience will allow. If the things I discussed take you by surprise then you've never really entered into a legalization discussion before, and you've never thought out the follow ons. I often overestimate people. Thanks for the correction.
I have a quick idea for you. Go down to your local bus stop at 3 AM with a friend. You take out a five dollar bill and wave it around. Have your friend announce that he's got 10 rocks of crack he'll sell for $5. You'll get a quick lesson on the value of "cheap drugs".
Do you think it will hurt less getting beaten for $5 than it would for $100?
