Probably the one law that really made marijuana illegal nation wide was the Marijuana Tax Act of 1937. The true story is too long to go into here, but for anyone willing to do their homework they will discover marijuana prohibition was created , not to protect society from the ‘evils of the drug Marijuana,’ as the Federal government claimed, but as an act of deliberate economic and industrial sabotage against the re-emerging industrial hemp industry, and blatant racism. For the uninformed, marijuana and hemp are the same plant with the exception being that the hemp plant contains little or no THC, the psychoactive substance in marijuana, as to render it useless for medicinal or recreational purposes. Much of this information is available on the net. I suggest people learn the truth about this benign drug and protest to their legislatures to stop arresting people for choosing their form of recreation. Over 70 million people have tried marijuana. Where are the jails to hold all these people?
