Marijuana is
the most commonly abused illicit drug in the United States. A dry,
shredded green/brown mix of flowers, stems, seeds, and leaves of the
plant Cannabis sativa, it usually is smoked as a cigarette (joint,
nail), or in a pipe (bong). It also is smoked in blunts, which are
cigars that have been emptied of tobacco and refilled with marijuana,
often in combination with another drug. It might also be mixed in food
or brewed as a tea. As a more concentrated, resinous form it is called
hashish and, as a sticky black liquid, hash oil. Marijuana smoke has a
pungent and distinctive, usually sweet-and-sour odor.(1)
The main active
chemical in marijuana is THC (delta-9-tetrahydrocannabinol). The
membranes of certain nerve cells in the brain contain protein
receptors that bind to THC. Once securely in place, THC kicks off a
series of cellular reactions that ultimately lead to the high that
users experience when they smoke marijuana.(2)
Marijuana is a Schedule
I substance under the Controlled
Substances Act (CSA). Schedule I drugs are classified as having a
high potential for abuse, no currently accepted medical use in
treatment in the United States, and a lack of accepted safety for use
of the drug or other substance under medical supervision.

When
marijuana is smoked, its effects begin immediately after the drug
enters the brain and last from 1 to 3 hours. If marijuana is consumed
in food or drink, the short-term effects begin more slowly, usually in
1/2 to 1 hour, and last longer, for as long as 4 hours. Smoking
marijuana deposits several times more THC into the blood than does
eating or drinking the drug.(4)
Within
a few minutes after inhaling marijuana smoke, an individual’s heart
begins beating more rapidly, the bronchial passages relax and become
enlarged, and blood vessels in the eyes expand, making the eyes look
red. The heart rate, normally 70 to 80 beats per minute, may increase
by 20 to 50 beats per minute or, in some cases, even double. This
effect can be greater if other drugs are taken with marijuana.(5)
As
THC enters the brain, it causes a user to feel euphoric— or
“high”—by acting in the brain’s reward system, areas of the
brain that respond to stimuli such as food and drink as well as most
drugs of abuse. THC activates the reward system in the same way that
nearly all drugs of abuse do, by stimulating brain cells to release
the chemical dopamine.(6)
A
marijuana user may experience pleasant sensations, colors and sounds
may seem more intense, and time appears to pass very slowly. The
user’s mouth feels dry, and he or she may suddenly become very
hungry and thirsty. His or her hands may tremble and grow cold. The
euphoria passes after awhile, and then the user may feel sleepy or
depressed. Occasionally, marijuana use produces anxiety, fear,
distrust, or panic.(7)
Someone
who smokes marijuana regularly may have many of the same respiratory
problems that tobacco smokers do, such as daily cough and phlegm
production, more frequent acute chest illnesses, a heightened risk of
lung infections, and a greater tendency toward obstructed airways.
Cancer of the respiratory tract and lungs may also be promoted by
marijuana smoke. Marijuana has the potential to promote cancer of the
lungs and other parts of the respiratory tract because marijuana smoke
contains 50 percent to 70 percent more carcinogenic hydrocarbons than
does tobacco smoke.(8)
Marijuana's
damage to short-term memory seems to occur because THC alters the way
in which information is processed by the hippocampus, a brain area
responsible for memory formation. In one study, researchers compared
marijuana smoking and nonsmoking 12th-graders' scores on standardized
tests of verbal and mathematical skills. Although all of the students
had scored equally well in 4th grade, those who were heavy marijuana
smokers, i.e., those who used marijuana seven or more times per week,
scored significantly lower in 12th grade than nonsmokers. Another
study of 129 college students found that among heavy users of
marijuana critical skills related to attention, memory, and learning
were significantly impaired, even after they had not used the drug for
at least 24 hours.(9)
Overall
marijuana production in Mexico--the principal source of
foreign-produced marijuana to U.S. drug markets appears to be
increasing. Mexico marijuana production estimates indicate that
production in Mexico was relatively low from 2000 through 2002 during
a period of drought, increased sharply in 2003 as weather improved,
and receded slightly in 2004 (see 2006 National Drug Threat
Assessment, Table
5). Moreover, anecdotal reporting and cannabis eradication and
marijuana seizure data all indicate that marijuana production in
Canada has recently increased, perhaps significantly. Domestic
marijuana production also appears to be increasing, according to law
enforcement reporting that reveals a significant increase in
eradication of domestic marijuana grow sites in 2005. Domestic
Cannabis Eradication/Suppression Program (DCE/SP) data indicate that
domestic cannabis eradication--occurring primarily in California,
Kentucky, Tennessee, Hawaii, and Washington, often on public lands
including Forest Service lands (see 2006 National Drug Threat
Assessment, Figure
2)--increased steadily from 2000 through 2003, decreased in 2004,
and increased sharply to its highest recorded level in 2005. (See 2006
National Drug Threat Assessment, Table
6.)(10)
Most
of the foreign-produced marijuana available in the United States is
smuggled into the country from Mexico via the U.S.-Mexico border by
Mexican DTOs and criminal groups; however, a sharp rise in marijuana
smuggling from Canada via the U.S.-Canada border by Asian criminal
groups has increased the domestic availability of marijuana produced
in Canada.(11)
Mexican
criminal groups control most wholesale marijuana distribution
throughout the United States; however, Asian criminal groups appear to
be increasing their position as wholesale distributors of
Canada-produced marijuana. According to law enforcement reporting,
Mexican DTOs and criminal groups control most wholesale marijuana
distribution in the Great Lakes, Pacific, Southeast, Southwest, and
West Central Regions and control much of the wholesale marijuana
distribution in the Northeast Region. Although Asian criminal groups
are not the predominant wholesale marijuana distributors in any
region, these groups, particularly Chinese and Vietnamese groups, now
are widely identified in law enforcement reporting as the principal
suppliers of high potency, Canada-produced marijuana throughout the
country.(12)
The
influence of Asian criminal groups in high potency marijuana
distribution is likely to increase in the near term. Law enforcement
reporting indicates that these groups are increasingly gaining control
over much of the high potency marijuana production and distribution in
Canada and now appear to be extending their influence in the United
States. In fact, law enforcement reporting indicates that the
influence of Asian organizations in drug trafficking--particularly the
trafficking of high potency marijuana--in the United States is now
more significant than that of Russian-Israeli, Jamaican, or Puerto
Rican criminal groups (see 2006 National Drug Threat Assessment,
Appendix A, Map
3).(13)
Marijuana
distribution is widespread throughout the country, as evidenced by the
presence of 14 principal distribution centers for the drug, one or
more of which are located in nearly every region of the country (see
2006 National Drug Threat Assessment, Appendix A, Map
6). Much of the midlevel and retail distribution of marijuana in
these and other cities is controlled by African American, Asian, and
Hispanic street gangs; however, independent dealers control most
midlevel and retail marijuana distribution in smaller communities and
rural areas. In fact, independent dealers are likely to retain control
of distribution in smaller communities because they often distribute
locally produced marijuana rather than foreign-produced marijuana.(14)
Among
students surveyed as part of the 2005 Monitoring
the Future study, 16.5% of eighth graders, 34.1% of tenth graders,
and 44.8% of twelfth graders reported lifetime use of marijuana. In
2004, these percentages were 16.3%, 35.1%, and 45.7%, respectively.(15)
Approximately
74% of eighth graders, 65.5% of tenth graders, and 58% of twelfth
graders surveyed in 2005 reported that smoking marijuana regularly was
a "great risk."(16)
The
Youth
Risk Behavior Surveillance (YRBS) study by the Centers for Disease
Control and Prevention (CDC) surveys high school students on several
risk factors including drug and alcohol use. Results of the 2005
survey indicate that 38.4% of high school students reported using
marijuana at some point in their lifetimes. Additional YRBS results
indicate that 20.2% of students surveyed in 2005 reported current
(past month) use of marijuana.(17)
Between
2001 and 2005, marijuana use dropped in all three categories: lifetime
(13%), past year (15%) and 30-day use (19%). Current marijuana use
decreased 28% among 8th graders (from 9.2% to 6.6%), and 23% among
10th graders (from 19.8% to 15.2%).(18)
Between October
1, 2004 and January 11, 2005, there were 1,777 Federal offenders
sentenced for marijuana-related charges in U.S. Courts. Approximately
94.9% of the cases involved marijuana trafficking. Between January 12,
2005 and September 30, 2005, there were 4,396 Federal offenders
sentenced for marijuana-related charges in U.S. Courts. Approximately
95.8% of the cases involved trafficking.(19)
In 2005, the
DEA seized 282,139 kgs of marijuana. For prior years, click

The campaign to
legitimize what is called "medical" marijuana is based on
two propositions: that science views marijuana as medicine, and that
DEA targets sick and dying people using the drug. Neither proposition
is true. Smoked marijuana has not withstood the rigors of science –
it is not medicine and it is not safe. DEA targets criminals engaged
in cultivation and trafficking, not the sick and dying. No state has
legalized the trafficking of marijuana, including the twelve states
that have decriminalized certain marijuana use.(20)
In the case of
United States v. Oakland Cannabis Club the U.S. Supreme Court ruled
that marijuana has no medical value as determined by Congress. The
opinion of the court stated that: "In the case of the Controlled
Substances Act, the statute reflects a determination that marijuana
has no medical benefits worthy of an exception outside the confines of
a government-approved research project."(21)
The case reached the U.S. Supreme Court after the federal government
sought an injunction in 1998 against the Oakland Cannabis Buyers
Cooperative and five other marijuana distributors in California.(22)
The United
States Court of Appeals for the District of Columbia Circuit issued a
ruling on May 24, 2002, upholding DEA's determination that marijuana
must remain a schedule I controlled substance. The Court of Appeals
rejected an appeal that contended that marijuana does not meet the
legal criteria for classification in schedule I, the most restrictive
schedule under the Controlled Substances Act.(23)
