
Consequences for Society
Rise in drug-related crime and violence
 DWI or DUI can result in collisions
 Affects the nation’s economy
 The Office of National Drug Control Policy shows
that drug costs the U.S. economy $180 billion per
year from:


Hallucinations and paranoia
Impaired short-term memory, reaction
time, concentration, and coordination
Lung irritation, coughing
Heart and lung damage
Increase risk of lung cancer
Weakened immunity to infection
Increase appetite
Increased risk of stillbirth and birth defects
Change hormones levels
In females, risk of infertility
In males, lowered sperm count and
testosterone levels

Physical Consequences of Marijuana
Use






Users face the same health risks as tobacco
smokers
Marijuana smoke contains more cancercausing chemicals than tobacco smoke
Users inhale unfiltered smoke, which can
cause damage to the respiratory system
Marijuana damage the immune system
In males it interferes with sperm production
and lowers levels of testosterone
In females it raises testosterone levels which
may lead to infertility or the inability to bear
children

Mental and Emotional Consequences
Marijuana raises levels of a brain chemical called
dopamine
 Dopamine produces a pleasurable feeling which can
be intense aka a “high”
 When the drug wears off the abrupt let down is
called a “crash”
 Paranoia
 Distorted perception, loss of coordination, and
trouble with thinking and problem solving


Driving and Marijuana Use
Marijuana interferes with depth
perception, decreases reaction time,
cause sleepiness, impairs judgment and
slows reflexes
 The National Highway Traffic Safety
Administration estimates that 10 to 22%
of drivers involved in car crashes were
on drugs
 Consequences of driving under the
influence of any drug – including
marijuana – includes:

 Suspension of a driver’s license, fines, loss
of eligibility for federal college loans, and
possibly a jail term


Smoking marijuana regularly (a joint a day) can
damage the cells in the bronchial passages which
protect the body against inhaled microorganisms
and decrease the ability of the immune cells in the
lungs to fight off fungi, bacteria, and tumor cells.
Regular smoking has been shown to materially
affect the overall ability of the smokers body to
defend itself against infection by weakening
various natural immune mechanisms, including
macrophages (mac-ro-phages) a.k.a. "killer cells"
and the all-important T-cells.


The main respiratory consequences of smoking
marijuana regularly (one joint a day) are
pulmonary infections and respiratory cancer
The effects also include chronic bronchitis,
impairment in the function of the smaller air
passages, inflammation of the lungs, the
development of potentially pre-cancerous
abnormalities in the bronchial lining and lungs,
and, as discussed, a reduction in the
capabilities of many defensive mechanisms
within the lungs.

Marijuana smoke and cigarette smoke contain
many of the same toxins, including one which
has been identified as a key factor in the
promotion of lung cancer. This toxin is found
in the tar phase of both, and it should be noted
that one joint has four times more tar than a
cigarette, which means that the lungs are
exposed four-fold to this toxin and others in
the tar.

It has been suggested that marijuana is at the
root of many mental disorders, including acute
toxic psychosis, panic attacks (one of the very
conditions it is being used experimentally to
treat), flashbacks, delusions, depersonalization,
hallucinations, paranoia, depression, and
uncontrollable aggressiveness. Marijuana has
long been known to trigger attacks of mental
illness, such as bipolar (manic-depressive)
psychosis and schizophrenia.

Anabolic-androgenic steroids are synthetic
substances similar to male sex hormones
Anabolic refers to muscle building
Androgenic refers to increased male
characteristics
Causes unnatural muscle growth
When combined with conditioning, steroids
can increase muscle strength, but the tendons
and ligaments don’t get stronger which can
lead to injury
