You confuse my meaning. I am against my own personal use of drugs, but would (with some caveats) support the legalization of all substances in any quantity, particularly prescription medications.

EDIT: my position, which would typically be described as extremely pro-drug, is largely due to my discomfort in treating medical personnel as de facto agents of the government on drug policy without requiring medical experts judge at trial for drug crimes like they do for malpractice proceedings. Essentially you have the people who decide what drug use is legal and illegal having no competent oversight -- we are in a nation with functionally no drug laws to the influential or wealthy enough to locate a doctor amenable to their suggestions, so why not at least offer everyone the same freedom until a more coherent policy is found?
