It has also been called weed, grass, pot, bud, dope, hydro, or reefer. According to streetdrugs.org this plant is grown in many different regions and can be cultivated indoors, as well as out. Although cannabis is the most common species, there are others as well. These include indica, sometimes called “Indian Hemp”, which can withstand colder climates, and ruderalis, which is grown in Siberia and West Asia.
The drug is obtained from the flowering tops, stems, and the leaves of the Cannabis sativa or the indica. The resin found on flower clusters and top leaves of the female plant is the most potent drug source and is used to prepare hashish, which is the highest grade of cannabis. The bud of the female plant is called sinsemilla, which means without seeds in Spanish, produces more psychoactive resin than male plants and is the part most often smoked as marijuana (factmonster.com). Dried marijuana buds, leaves, and flower can be crushed and rolled into joints. They can also be smoked in pipes.

There are more than 420 chemicals in a single cannabis plant. The most potent psychoactive chemical in marijuana is tetrahydrocannabinol (THC). It mimics the natural neurotransmitter anandamide. Cannabinol and cannabidiol are two other prominent cannabinoids, but they are not thought to have psychoactive properties. When smoked or ingested, these potent psychoactive chemicals are converted by the liver into more than 60 other metabolites, some of which are psychoactive. Although when smoked only about 20% of the THC in the joint is absorbed; however, the longer a lungful of smoke is held, the greater the amount of THC absorbed and the stronger the high (Uppers, Downers, All Arounders).
