Marijuana ( aka grass, pot, weed) is the common name for the crude drug made from the plant, Cannabis sativa. Over 400 chemicals are in marijuana, including the main mind altering ingredient, THC. The amount of THC in the marijuana determines how strong the effects will be. Factors of the strength of the marijuana is, the type of plant, weather, soil, and the time of harvest. Another form of marijuana is a joint. A joint is a cigarette made from the dried particles of the plant. Hashish or hash, is made by taking the flowers of the marijuana plant and the resin from the leaves and pressing it into cakes or slabs. Hash is usually stronger than regular marijuana, containing five to ten times as much THC. Pure THC is almost only available though research, so substances sold on the street claiming to be THC can turn out to be something else like PCP.
Not everyone uses marijuana just to get "high”. Marijuana can be used as medicine, helping cancer and AIDS patients gain appetite and relieve nausea. If marijuana was legal, the government would be able to enact standards of quality and purity of the drug. Eliminating the street drug which is often contaminated or extremely potent, causing disease and sometimes death for those who use it. But the most basic reason that marijuana should be legal is that there is no reason for it not to be. Individuals deserve the right to make choices for themselves. Last time i checked the government only have a right to limit those choices if the individual's actions endanger someone else. And this does not apply to marijuana, since the individual using it is doing it according to his or her free will. The second important reason that marijuana should be it that there is not good evidence that prohibition decreases drug use, in fact in some cases it might increase drug use. One unintended effect of the prohibition of marijuana is the popularity of it in high schools.
