Evidence of human use of
the cannabis plant goes back to 8000 BC in China, although it is
believed the plant originated in the region of present-day
northern India. Throughout history, people have produced
textiles, cordage, and other important materials from cannabis
fibers. Animals and humans have consumed cannabis seeds and seed
oil. And since early times, people have found medical,
spiritual, and psychological benefits from the use of the
flowering buds of female cannabis plants.
Ancient herbal remedies applied marijuana for a wide range of
ailments, including constipation, rheumatic pain, female
disorders, earache, jaundice, glaucoma, asthma, muscular
dystrophy, epilepsy, and excitability. It was used to prolong
life, improve judgement, lower fevers, induce sleep, stimulate
appetite, aid in childbirth, and better the voice. Queen
Victoria is said to have sipped marijuana tea for menstrual
cramps.
Cannabinoids are the active ingredients in marijuana.
Delta-9-tetrahydrocannabinol (THC) is the primary active
cannabinoid -- the part that produces intoxication and most
therapeutic effects. In 1992, scientists discovered that the
human brain is flooded with naturally-occurring cannabinoids,
which they labeled "anandamide" from the Sanskrit word meaning
"internal bliss." Latching onto tiny receptor sites all over the
brain, anandamides play key roles in keeping us
healthy, happy, and free of pain. While cannabinoids are common
in human and animal nervous systems, marijuana is the only plant
known to contain them.
In 1937, cannabis "marijuana" was placed on a restricted
status through use of tax laws by the U. S. Congress, over the
objections of the American Medical Association. In subsequent
decades, restrictions were strengthened as a result of
propaganda from federal law enforcement agencies. After
widespread usage by young people in the 1960s, federal drug laws
placed marijuana in the most restricted category, Schedule I,
which defines marijuana as having no medical value. There was no
scientific evidence behind this decision.
Since the 1970s, efforts have been made to remove marijuana
from Schedule I and/or to make it available for medical use. The
U. S. Drug Enforcement Agency's administrative law judge Francis
L. Young, after reviewing the evidence for a 1989 hearing,
concluded not only that marijuana's medical utility had been
adequately demonstrated, but that marijuana had been shown to be
"one of the safest therapeutically-active substances known to
man." Unfortunately, without stating any reason, DEA
administrators refused to abide by his recommendation to
reschedule marijuana to a less-restrictive category.
After an eighteen-month study commissioned by the National
Office for Drug Control Policy, the Institute of Medicine
concluded in its 1999 report that:
"The accumulated data indicate a potential
therapeutic value for cannabinoid drugs, particularly
for symptoms such as pain relief, control of nausea and
vomiting, and appetite stimulation.
"In most cases, there are more effective medications.
However, people vary in their responses to medications
and there will always be a subpopulation who do not
respond well to other medications.
"Psychological effects of cannabinoids, such as
anxiety reduction, sedation, and euphoria can influence
their potential therapeutic value. Those effects are
potentially undesirable for certain patients and
situations, and beneficial for others.
"Marijuana is not a completely benign substance. It
is a powerful drug with a variety of effects. However,
except for the harms associated with smoking, the
adverse effects of marijuana use are within the range of
effects tolerated for other medications.
"Because of health risks associated with smoking,
smoked marijuana should generally not be recommended for
long-term medical use. Nonetheless, for certain
patients, such as the terminally ill or those with
debilitating symptoms, the long-term risks are not of
great concern. Further, despite the legal, social, and
health problems associated with smoking marijuana, it is
widely used by certain patient groups.
The report has been criticized for refusing to consider any
patient's direct experience with marijuana. All studies reviewed
were laboratory experiments on animals or involved synthetic
THC. See the full report at

A significant amount of medical research has been accumulated
showing beneficial effects of marijuana use. Legitimate studies
have not been able to prove marijuana harmful to health,
especially compared to prescription drugs often used by patients
who gain benefit from marijuana use. Many patients report that
marijuana is less harmful than the prescriptions, including
medications for pain, muscle spasticity, digestive disorders,
and appetite stimulants.
Critics argue that marijuana use should not be approved by a
popular vote, but rather by an action of the Food and Drug
Administration. However, FDA approval involves requirements that
marijuana will most likely never meet. First, a ‘sponsor’ must
spend millions of dollars to produce the necessary laboratory
tests. It is not likely that such an investment would be made,
since many potential ‘customers’ for this substance would simply
grow their own. Second, a complex natural substance such as
marijuana is not easily tested, since tests are geared toward
single-ingredient synthetic drugs.
Marijuana’s primary active ingredient, THC, has been
synthesized as a pharmaceutical drug, most often marketed as
Marinol. This disproves marijuana’s placement in Schedule I as
having no medical value. Marinol is not as effective as natural
marijuana and is very expensive.
Some opponents of marijuana as medicine argue that its users
would be hazardous to the work place and community. However,
prescription drugs often carry warnings about operating
machinery and driving. A study performed for the UK Department
of the Environment, Transportation and the Regions by the
Transport Research Laboratory, "The Influence of Cannabis on
Driving," concludes that though cannabis intoxication does have
an effect on driving ability, the effects of alcohol are much
worse, and that marijuana users notice their impairment and
compensate by driving slower and more carefully. Click here to

Advocates for medical marijuana argue that the choice whether
to use marijuana in medical applications should be a decision
made by a patient and his/her medical professionals, not by an
act of government that is based on social hysteria. State laws
allowing medical use began to gain passage in the early 1990s
after a federal program which had dispensed marijuana to
selected patients had been closed to new applicants. As of July
2006, five patients continued to receive a monthly
federally-supplied canister of 300 pre-rolled marijuana
‘cigarettes’ from the federal marijuana farm in Mississippi.
