Illegal Drugs
What is a drug?





A chemical that causes a physiological or
psychological action in the body
Illegal drugs are abused because they
produce a euphoric effect
Euphoria – a deep sense of well-being
Why do many people take illegal drugs?
It makes them feel good!!!
Price of euphoria…


Tolerance – occurs when, over time, an
ever-increasing dose of a drug is required
Physical dependency



results when the body becomes accustomed
to the regular intake of a drug
Can happen if the drug user takes a new dose
before the effects of the previous dose have
worn off
Withdrawal sickness (cramps, nausea, chills,
vomiting, insomnia, convulsions, pain, and
hallucinations)

Psychological dependency


deep need for the continued intake of a drug
occurs in an individual
Ex. Rat, two levers, cocaine, food


Illegal drugs that show up in arrests on
the street
37% identify cocaine as the major drug
threat
36% methamphetamine
13% marijuana
9% heroin
1% 3,4-methylenedioxymethamphetamine
History of Cocaine






Leaves of the coca plant, Erythroxylon coca, were given
to Inca royalty in keeping with their religious and cultural
beliefs
The SA Indians chewed on the leaves to get additional
strength and endurance
In the 1880s Sigmund Freud considered cocaine a
miracle drug that led to clarity of mind
In 1886 the Coca Cola Co. marketed its new soft drink,
made from the same coca leaves, as an alternative to
alcoholic drinks
One bottle of Coca Cola contained about 60 mg of
cocaine
In 1903 the co. was forced to remove cocaine from its
beverage, but it still uses the leaves for flavor
Methods of extracting cocaine






Leaves mashed and soaked
Cocaine extracted with help from a solvent
Extract is 70% cocaine hydrochloride
Cocaine hydrochloride is a salt and can either be
injected intravenously or inhaled through the
nose
When mixed with an aqueous solution of baking
soda and heated, the basic form of the drug is
obtained
As the mixture is heated, a cracking sound is
produced, hence the name crack cocaine
Effects




Stimulant
effects can last from 15-30 minutes to an hour,
depending upon the method of ingestion
increases alertness, feelings of well-being and
euphoria, energy and motor activity, feelings of
competence and sexuality
Athletic performance may be enhanced.
Anxiety, paranoia and restlessness are also
frequent.
With excessive dosage, tremors, convulsions and
increased body temperature are observed
Methamphetamine





user

common form; produced in illegal labs; can be
injected, snorted, ingested, or smoked
Ice – also known as glass, batu, or shabu;
made by recrystalizing powdered meth. In a
solvent such as water, alcohol, or acetone;
usually smoked
Tablets – normally manufactured in Burma; can

Marijuana Facts






mild hallucinogen
Most commonly used illegal drug in the U.S.
Estimated that more than 12 million Americans
above the age of 12 use marijuana at least once
a month
Estimated that about 54% of the population
between the ages of 18 and 25 have tried it
Used in Chinese medicine as early as 2737 B.C.

nausea, and labor pains






Greenish-brown mixture of the leaves, flowers,
stems, and seeds of the plant Cannabis
Grows in most parts of the world
Active ingredient is tetrahydrocannabinol (THC)
Marijuana and other cannabis products are
usually smoked
can be brewed into tea or mixed in baked
products (cookies or brownies).
Used to treat glaucoma and to lessen nausea
caused by anticancer drugs and AIDS treatment
Effects


Bind to specific receptor sites in the human brain which
trigger the euphoric effect for which the drug is taken
dry mouth and throat, increased heart rate, impaired
coordination and balance, delayed reaction time, and
diminished short-term memory


Moderate doses tend to induce a sense of well-being and
a dreamy state of relaxation that encourages fantasies,
renders some users highly suggestible, and distorts
perception (making it dangerous to operate machinery,
drive a car or boat, or ride a bicycle).
Stronger doses prompt more intense and often
disturbing reactions including paranoia and
hallucinations.

Before it was made a controlled substance,
MDMA was used as an augmentation to
psychotherapy, often couples therapy, and to
help treat clinical depression as well as anxiety
disorders.
Clinical trials are now testing the therapeutic
potential of MDMA for post-traumatic stress
disorder (PTSD) and anxiety associated with
terminal cancer

Rate of Absorption




Quantity of alcohol
consumed
Time over which the
alcohol was
consumed
Form of the alcohol
Contents of the
stomach
Field Sobriety Tests

Horizontal gaze nystagmus (HGN)




Involuntary jerking of the eye that occurs
naturally as the eyes gaze to the side
Under normal conditions, this occurs when
the eyes are rotated at high peripheral angles
Under the influence of alcohol, it is
exaggerated and may occur at lesser angles
Difficulty following a slow moving object
horizontally

Walk and Turn



Subject is directed to take nine steps, heel-totoe, along a straight line
After taking the steps, the suspect must turn
on one foot and return in the same manner in
the opposite direction
Indicators of impairment: lack of balance,
begins early, stops to regain balance, doesn’t
touch heel-to-toe, steps off line, uses arms to
balance, makes an improper turn, or takes
incorrect number of steps


Intoxilyzer 5000




Person give 3 chances to blow sufficient breath
into a disposable mouthpiece
If the subject fails to provide enough breath, it is
considered a refusal
Once the breath is trapped within a transparent
chamber, an infrared beam of light is passed
through it
Instrument measures the absorption of infrared
light by the alcohol in the breath and uses this
to calculate the BAC
