Marijuana

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
called "hence." The mind-altering drug in marijuana is called
"Delta-9-Tetrahydrocannibinol," or THC. The mildest form
of marijuana contains between zero to three percent of
THC. Most of the THC is contained in the resign, which is
secreted around the flowers, seeds, and topmast leaves.
Until recently it was thought that only the female plant
contained the drug. But it is now known that both the
female and the male plants contain THC. THC stays in the
body for about 28 days. Marijuana can be prepared many
different ways therefore it has many different ways of
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
foods. When consumed in foods the effects start after one
half-hour and last from three to four hours. The potency of
Marijuana has increased at least ten times or 275% since
the 1960's. Marijuana can be measured by it's "therapeutic
ratio," (the difference between the size of the dose needed
for the desired effect and the! size that produces
poisoning). The therapeutic ratio in marijuana has yet to be
found. The negative long term effects of heavy marijuana
use are, possible lung cancer, heart attacks in juveniles,
strokes in people under forty, and it depletes the brain of
