William F. Buckley and Milton Friedman have long supported legalizing marijuana. Years ago, Buckley publicly announced that he had smoked marijuana on his boat off the coast outside the three mile limit (unlike me, who have never tried it). Now 78 years old and giving up ownership of the National Review, Buckley writes in National Review Online in support of complete legalization and speaks as well of medical cannabis:

But the stodgy inertia most politicians feel is up against a creeping reality. It is that marijuana for medical relief is a movement which is attracting voters who are pretty assertive on the subject. Every state ballot initiative to legalize medical marijuana has been approved, often by wide margins. Of course we have here collisions of federal and state authority. Federal authority technically supervenes state laws, but federal authority in the matter is being challenged on grounds of medical self-government. It simply isn't so that there are substitutes equally efficacious. Richard Brookhiser, the widely respected author and editor, has written on the subject for The New York Observer. He had a bout of cancer and found relief from chemotherapy only in marijuana — which he consumed, and discarded after the affliction was gone.

The court has told federal enforcers that they are not to impose their way between doctors and their patients, and one bill sitting about in Congress would even deny the use of federal funds for prosecuting medical marijuana use. Critics of reform do make a pretty plausible case when they say that whatever is said about using marijuana only for medical relief masks what the advocates are really after, which is legal marijuana for whoever wants it.

That would be different from the situation today. Today we have illegal marijuana for whoever wants it. An estimated 100 million Americans have smoked marijuana at least once, the great majority, abandoning its use after a few highs.
