Cannabis Sativa (marijuana) has been thought to
             be an illegal and very harmful drug for many years. But as
             you read this report you will learn that marijuana has been
             around for many years (most years legal) and isn't as
             harmful as some people may think. Marijuana has been
             used for many things in the past, including medicine, hemp
             rope, crude cloth and enjoyment. Now it is mainly used as
             a narcotic. Marijuana is an illegal weed that grows up to
             eighteen feet tall with little or no cultivation. The plant has
             many branches that extend with large, hairy, pointed leaves
             with saw tooth edges. Marijuana grows wild all over the
             world and in some states and countries it's legal. Cloth and
             rope are made from the stem which contains a tough fiber

             entering the body. When smoked the THC goes into the
             lungs, directly into the bloodstream and to every cell in your
             body. The effects depend upon the level of potency and
             how much is consumed. The main effects of smoking are:
             the heart rate may increase from 80 beats to 150 beats a
             minute, the bronchial tubes enlarge and become relaxed
             allowing extra oxygen to enter the body, giving a "High" like
             feeling. There are no immediate physiological effects. The
             feeling usually lasts from one to three hours. Marijuana can
             also be ingested as a drink, cakes, brownies or many other
