Ron, Mr. Cann.com himself, bought some at an auction not too long ago and showed them off on the boards, if I'm not mistaken.
Back in the 1930's everyone thought the federal government had no right to regulate what individuals ingested (state and local governments could though). This is why the nationwide Prohibition of alcohol was a Costitutional Amendment.

So the sneaky bastards in Congress, cheered on by powerful folks with vested interests such as William Randolph Hearst (This is confirmed in HOOKED by what Harry Anslinger [1st head of Bureau of Narcotics appointed by Andrew Mellon, financial associate of the DuPonts] told his biographer. Hearst met with Anslinger to encourage a federal law, and bragged that he personally wrote all the articles in his papers about the marijuana menace!) and the DuPonts, passed the Marijuana Tax Act of 1937 as a way of legally undermining the Constitution of the United States.


The thing was, to get a stamp you had to have the marijuana, but it was illegal to have the marijuana without a stamp.
Cute, huh?

However, in an ironic twist of fate, everyone was wrong about everything.
In 1970, I believe, they decided that magically, though the Constitution hadn't changed in this respect, the federal government COULD make laws regulating what individuals ingested, and Congress established the DEA.
This was right after the Supreme Court decided that the Marijuana Tax Act WAS unconstitutional.



Oh yeah, and as much as I watch The History Channel, I can't believe I missed the THC!
