Marijuana is a drug that is essentially the bud or flower of the Cannabis plant. Cannabis has been around for thousands of years, and has been referenced in writings as early as 2727 B.C. The reasoning behind this is that Cannabis is one of the few, if not the only plant on the planet that yields a drug and a useful and strong fiber. This fiber is called Hemp.
After being used for medicinal purposes in China for hundreds of years, Cannabis is brought to Europe through India and Africa in 500 A.D., where it is primarily grown for the hemp. In 1492 Christopher Columbus brings Cannabis with him to the new world to use the hemp to produce cloth, rope, and paper. Cannabis then went on to become the primary crop that our first president, George Washington grew in Mount Vernon. In 1908 Henry Ford the inventor behind the assembly line, used Hemp plastic make is first Model T Ford. He also uses Hemp ethanol to power it. In 1937 the U.S bans Cannabis in America only to use it in 1942 as truth serum for their prisoners of war. By the early 60's somewhere around a million Americans had tried Marijuana. That number had grown to over 30 million by the early 80's. In the mid 90's Proposition 215 is passed in California which allows the use of Marijuana for medical uses. And although Cannabis remains illegal in the U.S., as it stands now it is the #1 cash crop in the U.S
at $36 Billion.
