Our fore fathers thought marijuana was ok?

so why do the Nazis of today's America want to ban it.... it would take 800 joints to kill a person—but the cause of death would be carbon monoxide poisoning..... The first recorded use of marijuana as a medicinal drug occurred in 2737 B.C. by Chinese emperor Shen Nung. The emperor documented the drug’s effectiveness in treating the pains of rheumatism and gout..... The first law in the American colonies regarding marijuana was a 1619 law that actually required farmers to grow the hemp plant. Once harvested, hemp was useful for clothing, sails, and rope..... Prior to its ban, hemp was a staple cash crop of the family farm in early America. The first two drafts of the United States Declaration of Independence were written on paper made from hemp.
