It isn't pointless to debate the efficacy of drug laws. We either get tougher, which means death penalties for dealers and hard time for casual users, or we legalize the stuff and let people deal with it in their own way. At some point, we may find that people are actually able to deal with it. Then, all those people spending their lives in an underground economy will have an incentive to open some more legitimate business, and the people that do drugs won't have to steal my iPod or my laptop or my car to keep up their habit. Conservatives are, after all, for less government, and drug laws are not a very good example of less government.
No, I said it was pointless to have another pro/anti-WOD thread on FR, which ends up nothing but flamebait. I am familiar with your viewpoint, and have seen it endlessly stated on this forum for over 8 years. Problem is, I, and many others take exception to it. Do I favor harsh penalties for dealers, I very much do. For "users", I favor one of two options, treatment or jail. A society has a right to have basic health and safety (nevermind moral) standards, and there is no one in this nation that can make the argument that they have a need to engage in casual usage. To say it isn't harmful is absurd. Unless you're by yourself on some deserted island, it IS going to have a negative impact on others.
As for the property crime aspect, that too is a bogus argument. Even if it were legalized entirely, you'd have to go so far as to have the government financially subsidizing users to perhaps prevent some property crime to pay for habits (but then, some of that property crime may also simply be done for "kicks", as one isn't often in their right mind when they're on drugs). I'm sure that would go over really well amongst Conservatives. As for violent crimes, I believe under legalization, it would explode beyond belief. Without a moral or legal stigma, many countless more adults and children would get hooked. That would be a disaster of epic proportions, and the costs of dealing with it far greater than the current problem.
