Marijuana is widely used and it is estimated that nearly 25% of Americans have used marijuana once in their lives and that 2-5 million people use it daily despite it being illegal. Marijuana is a mixture of crushed leaves, flowers, small branches, stems, and seed of the hemp plant. This plant grows best in tropical climates and can be found throughout the world. Most countries cultivate this plant on purpose. Cannabis Indica species can withstand colder climates (“Marijuana, history of,”) If marijuana were to become a cash crop it would be the largest grown in the United States. It is one of the most commonly used drugs in the world, following caffeine, nicotine, and alcoholic beverages in the popularity.
