THE TRUTH ABOUT
HEMP

The
hemp plant is an amazing example of nature's blessings. No other plant can
produce clean fuel, medicine, high-quality protein, among the best edible oils,
lubricating and fuel oils, plastics, building material, clothing and paper. Hemp requires no pesticides, grows almost
anywhere on marginal soil, prevents soil erosion and can be grown on the same
land year after year. This article
is the sad story of hemp in America.
Hemp
played an important role in our history. Today it could help our economy, save
the forests and soil and clean up the air and water. Hemp cultivation was
banned in 1937 because it competed with the oil, chemical and timber
industries, not because of drug abuse.
Canada
and most European and Asian nations permit hemp cultivation. Growing hemp does
not mean legalizing marijuana. The variety used industrially does not contain much
THC, the major psychoactive chemical that some people like to smoke.
HEMP IN
HISTORY
Remnants
of hemp cloth were found in what was ancient Mesopotamia, now Turkey. Pottery decorated by pressing strips of
hemp cord into it were found in Taiwan from about the same time. The Egyptians spun hemp around 4000 BC. The word for hemp in German is hanf,
from which we get our English word hemp.
The
oldest paper came from China, made from a mixture of flax and hemp. In Japan, the emperor wore silk, but the
common people wore hemp clothing. The
Romans used hemp to make sails and ropes for their ships, and paper on which to
write their laws. The Dutch made a
light fabric out of hemp they called canefas, derived from the Latin word
cannabis. It resulted in our word
'canvas'. In other words, canvas
was originally a hemp product.
Records
from the 1600s describe hemp made into towels, tablecloths, napkins, sheets,
horse blankets, flags and so forth. The French philosopher Rablais wrote of
hemp,
"Without it, how could water be drawn from the well? What would the scribes, secretaries and
writers do without it? Would not the noble art of printing perish?"
HEMP PAPER
Hemp
paper does not turn yellow and disintegrate, as wood pulp paper does. The
Library of Congress reports that 300-400 year old hemp paper is still in good
shape. However, 97 percent of the non-fiction books printed between 1900 and
1939 on wood-based paper will be unreadable in 50 years.
Hemp
can be made into every grade of paper, from fine stock to index cards,
corrugated cardboard and newsprint. Today it is still used in cigarette paper, currency,
fine art stock and security papers like stock certificates. Bibles are often
printed on hemp paper because its lightness allows many thin pages.
Hemp
produces about four times as much pulp for paper per acre as trees. A new crop
is produced annually, unlike trees which require 20 years to mature. In 1988,
226 million tons of trees were pulped to make paper. The demand is expected to
double by the year 2020.
Wood-based
paper-making is a dirty industry. Mercury
and other toxins are released that have contaminated every water supply in the
nation. Hemp can be made with a soda process that is much cleaner. It can be bleached with hydrogen
peroxide, instead of toxic chlorine. Hemp paper can be recycled an average of
seven times. Wood-pulp paper can only be recycled an average of three times.
China leads the world today in non-tree paper, with 75% of their paper made
from various crops including hemp.
HEMP IN
AMERICA
An
early American explorer in 1524 described the American natives as using
"threads of wilde hemp." Christopher Columbus's ships each carried
over 80 tons of hemp rigging and sails. Many colonies, from Connecticut to Georgia, urged settlers to
raise hemp. Georgia offered
hempseed free to farmers in 1767.
Thomas
Paine insisted America could win a war with the British king because "hemp
flourishes here". George
Washington was a hemp farmer who praised native Indian hemp. The Declaration of
Independence and the Constitution were drafted on hemp paper. Thomas Jefferson wrote that hemp
"is of first necessity to the commerce and marine, in other words to the
wealth and protection of the country."
In
the 19th century, canvas and a lighter weight hemp fabric called 'duck' covered
the Conestoga Wagons. Kentucky
became the leading hemp-producing state. "Flanders fine hemp linen"
was advertised.
An
acre of hemp will produces two to three times as much fiber as cotton or flax. Hemp was always preferred to cotton
because of its far greater strength, absorbency and durability. In 1840, John Baxter wrote that, "hemp
will bleach whiter than flax or cotton, and make the finest fabric, from lace
to cambric to good shirting, and far cheaper than either." Cotton is the
most heavily sprayed crop in America. Hemp requires no pesticide spraying.
The
first Levi jeans were made of duck, a rugged hemp fabric. Hemp can compete well with synthetic
fibers, is breathable, recyclable and non-allergenic. Hemp can also be spun into rayon. Growing hemp could help revive the
textile industry in America, creating thousands of jobs.
Hemp
fiber is two to three times as strong as jute or sisal. This makes hemp
excellent for cordage, ropes and natural carpeting. Because hemp is unaffected by salt water, it is excellent for
fishing lines, fish nets, sail cloth and other items that are routinely exposed
to damp weather.
HEMP FOR FOOD
AND MEDICINE
Hempseed
is about 25% protein. It is a high-quality, nutritionally-complete food eaten
in many cultures for thousands of years. In the Orient, it was often eaten like oatmeal. It is more digestible than soy protein
and provides essential omeg-3 fatty acids, fiber and a complete protein all in
one food. Hempseed cakes make
excellent food for fish, birds and livestock.
Hempseed
oil is among the very best oil for eating raw or cooking. It is also excellent for lubricating
oil and fuel oil. It can be used
in shampoo, hair and skin cream, soap, cosmetics, massage oil and moisturizers.
The oil also makes excellent paint, varnishes, lacquer and sealants. In fact, when hemp cultivation was
banned in 1937, hempseed oil was exempted, as it was so important for paints,
varnishes and lubricating oil.
Hempseed
oil has the highest total concentration of the essential fatty acids of any oil
(about 80%). Flaxseed oil is
higher in linolenic acid, but hempseed is highest in total omega-6 (linoleic)
and omega-3 (linolenic) essential fatty acids. These fatty acids have been
shown helpful to combat cancer, AIDS, inflammation, ADHD and most other
diseases as well. It is
desperately needed by all people today.
UCLA researchers R. Lee Hamilton, PhD
and William Eidelman, MD stated, "essential fatty acids are responsible
for our immune response. In the (European) old country, the peasants ate hemp
butter. They were more resistant
to disease than the nobility."
Hemp
is a very ancient source of medicine. It is mentioned by the famous physician Galen. Several chemicals have been isolated
from the hemp leaf and seeds. Medicinal effects include stimulating the
appetite, reducing nausea, lowering pressure in the eyes, stimulating the
immune response and reducing pain, especially migraine headache pain.
It
is an antibacterial, antiviral, anti-convulsant, bronchodilator and
expectorant. It reduces spasticity
and ataxia in multiple sclerosis, stops menstrual bleeding and helps PMS and
the pain of childbirth. Hemp
extracts were widely used in medicines in America until it was banned.
HEMP FOR FUEL
Corn,
tree pulp and hemp are sources for clean-burning alcohol, ethanol and methane
gas. These 'biofuels' contain no
sulfur, the pollutant that causes acid rain. Growing the fuel also produces oxygen, to balance the oxygen
consumed during combustion. Engines
stay cleaner and the air remains much cleaner.
Hemp
may be the most profitable and productive fuel crop that can be grown in many
areas of America. Hemp can produce
about 1000 gallons of methanol per acre, four times as much as can be produced
from trees. Fuel can be produced
locally, reducing transportation costs. The production process, called biomass conversion, is safe
and clean. It would create a
domestic fuel industry, freeing us from Middle East oil dependency, providing
jobs and keeping our currency at home.
Hemp
fuel needs no taxpayer subsidies, as oil receives. The Department of Energy
estimated that fuel could be produced from hemp for about 60 cents per gallon. In New South Wales, Australia the
Minister of Energy told the parliament they should consider burning confiscated
hemp to produce electricity. "It burns at extremely high temperature,
produces a lot of power and is cheaper (and much cleaner) to burn than
coal."
Hemp
was the subject of a 1991 conference held in Wisconsin. One speaker pointed out
our government spends $26 billion each year to pay farmers not to cultivate
their land. Instead of this waste of taxpayer money, farmers could grow hemp or
other fuel crops. This could completely end our dependence on foreign oil.
HEMP FOR
PLASTICS AND CONSTRUCTION
It
sounds incredible, but almost any product made from petroleum can be made from
hemp or other vegetable sources. Price
has made oil attractive. However,
it is an artificial price. Oil is
heavily subsidized through oil depletion allowances and other tax breaks. Oil is polluting and is a finite
resource.
Henry
Ford of Dearborn, Michigan pioneered making plastics from vegetable matter. He
demonstrated how to make plastic steering wheels and many other car parts from
soybeans and other vegetable matter. Vegetable-derived plastics are also more easily recyclable.
Construction
materials such as particle board, shingles, blocks, paints, and sealants can
also be made from crops such as hemp.
BANNING HEMP
In
the late 1800's hemp had trouble competing with cheaper cotton for clothes,
jute for rope, and tree pulp for paper. However, by 1920, new processing equipment made hemp very
inexpensive. This was the beginning of the end for hemp.
Sometimes
laws arise out of greed and special interests. Other times, laws have good, but
misguided intentions. The banning of hemp involved both. Two fledgling
industries, oil and timber, ganged up against hemp.
Anything
made of petroleum can be made from hemp. The oil industry wanted cars to burn
gasoline, not alcohol fuel derived from plants. Randolph Herst, the newspaper magnate, owned forests across
the country. He wanted trees cut
for paper, rather than using hemp.
Herst
began publishing horror stories in his newspapers across the country about
"marijuana". By the way,
Hurst made up the word based on lyrics in a Mexican drinking song. He
fabricated stories of murderous Mexicans high on 'dope'. This was a word for
narcotics, not hemp. The stories
frightened and inflamed the public.
It
was the time of the great depression. People had lost confidence in their ability to solve their
problems. They wanted the
government to solve them. President
Franklin Roosevelt obliged by creating federal agencies to police every aspect
of American life. One was the
Federal Bureau of Narcotics. Alcohol
prohibition had been a failure, so the bureau was looking for a new 'war' to
undertake.
Hemp
leaves are not a narcotic drug. No
addiction to hemp was reported, even among hemp laborers. There was no drug problem in America to
speak of at that time. However,
hemp smoking made a good target due to the inflammatory newspaper stories.
The
combination of special interest greed and misguided government intervention led
to banning all hemp cultivation and possession in 1937. Imported hemp oil for
medicine and industry was so important to America it was excluded from the ban.
HEMP FOR
VICTORY
The
ban didn’t last long, however. Hemp
had a short revival during World War II. In 1942, the Japanese seized the Philippine Islands, our
source for jute rope fibers. Hemp
became essential for the war effort.
The
US government made a stirring film entitled “Hemp for Victory”. They urged
farmers to grow hemp for rope, twine, rigging and parachutes. Each battleship required 34,000 feet of
rope. Cultivation went from zero to one million acres in a few years. Even rural school children were
encouraged to plant hemp to help the war effort. Oddly, it did not cause a drug epidemic! All this was
forgotten when the war ended and hemp was banned once more.
The
Drug Enforcement Agency opposes legalizing hemp because they say it is just a
step toward legalizing marijuana. However, hemp is grown throughout Europe,
Canada and Asia, with permits or licenses. Most of these nations have far less
drug problems than we do!
Arizona
and California passed referenda legalizing cannabis for medical use, but the
people’s will has been ignored. A
coalition of farmers in Kentucky has also filed suit against the DEA claiming
the ban on hemp cultivation for industry was never the intent of Congress.
Imprisoning
hundreds of thousands of Americans, and turning the nation into a police state
has not stopped the drug problem. It
has probably made it worse. The
lucrative illegal trade in hemp fuels street gangs, drug cartels and terrorist
groups.
It
has brought down entire nations such as Columbia and today Mexico and turned
them into battlegrounds between competing drug lords. The ban has cost us dearly in freedom and rights. Swat teams and armed drug agents violate
sacred property and privacy rights looking for house plants.
Maybe
it is time to leave the emotion behind and rethink the ban on hemp cultivation.
The hemp law was motivated by
special interests. Banning a plant
is thoroughly repugnant to our Constitution because the only way to enforce it
is to invade everyone’s privacy. The
current policy does not work anyway and it deprives us of one of nature's
greatest sources of wealth and abundance.
