I think it would be more a Libertarian view than neo-con. The neo-cons are staunchly against any legalization of marijuana, or any other "drug", including for medicinal use.
You'd be surprised by many of my political views. I'm also a gun owner, and am against most laws regulating ownership and use. I have several others, most of which can be attributed to my being raised, and living most of my life, in the Midwest.

Anyway, having some intimate knowledge of controlled substances, both from professional and personal experience, I find most of the hype and propoganda pushed by the Government/DEA to be complete bullshit. I know MANY professionals, in varied fields, who are regular users of marijuana. They continue to excell in their respective careers.

Let's look at the Netherlands and their treatment of marijuana as an example of harm reduction when sensible laws are in place. Marijuana use is actually lower than in the U.S.

Don't get me wrong, their are some really nasty drugs out there, but their prohibition, and the "War on Drugs", don't help, and there's ample evidence showing that it actually increases use.
Make the problem a social one, not legal, and stop disrupting the lives of innocent people unnecessarily.

At least stop fucking with old hippies.
