The effects of alcohol were pretty well known long before 1933.
I hate to bust your bubble but there are meny health reasons not to use the drug. The main one for me is that the person smoking this crap always gets blasted,(drunk on his ass) there is no part way.
Where do you get this crap? That is flat-out completely untrue. There is also no boogeyman, no Easter bunny, babies aren't delivered by a stork, and you won't go blind if you touch yourself. No, I don't know why grown-ups told you these things when you were little.
I would look for alcohol to be outlawed before pot is lawful.
That would be the answer to the most fervent prayers of organized crime everywhere, not to mention anyone who wants to bring about a police state.
40% of adults have used marijuana at some point in their lifetime; why not expand the pool of criminals to encompass the 83% who've used alcohol? I mean, no one is concerned about the rights of criminals, so if we can just make everyone a criminal, that whole pesky civil rights thing goes right out the window.
I particularly enjoy seeing pro-legalization folks go off like drill sergeants on anyone who gets a fact about marijuana wrong, even though one of the central tenets of pro-legalization arguments is that the government and foundations spend billions each year to tell people falsehoods about pot.
Pot's supposed to make you mellow, remember? :-)
