Marijuana was criminalized thanks to DUPONT and other oil/textile companies. Hemp was first used for ethanol fuel. Oil companies didn't like this because weed is so easy to cultivate, thus cheaper to produce.  Anyone would have been able to just grow their own fuel rather than line the pockets of the Rockefeller monopoly. So, these lobbyists whined enough and got it criminalized. You lose faith because someone stands up against the war mongering oil companies and for the right to use a plant for whatever (FFS). Guessing you're all for bombing the hell out of poor countries for their oil resources.
