I am Cannabis also known as marijuana, ganja, weed, pot, bud... My Major active chemical is delta-9-tetrahydrocannabinol also known as THC. Humans have been consuming marijuana since before time but not until the 20th century there was a rise for recreational, relegious, or spiritual and medical purposes. It is said that about 1% of adult population use marijuana daily and annually almost 10% use marijuana. Also I did not become illegal until 20th century. LEGALIZE!
