The difference between CBD and Marijuana is the concentration of THC. THC is the chemical that gets you high. CBD is the medicinal benefit side of Cannabis.

The Marijuana Tax Act of 1937 removed Hemp based products from store shelves and growers in the United States.

Prior to 1937 Hemp was a major agricultural  product in the US. Cattle grazed on Hemp that naturally grew in the wild. Due to this CBD was ingested thru meat consumption.

With the passage of the 2014 Farm Act, CBD products are now filling our Endo Cannabinoid System, putting our body into a place of homeostasis, or balance.
