What
is Cocaine?
Cocaine is a powerfully addictive stimulant that
directly affects the brain. It is one of the oldest
known drugs. The pure chemical, cocaine hydrochloride,
has been abused for more than 100 years. And the coca
leaves, the source of cocaine, have been ingested for
thousands of years. Cocaine is a Schedule II drug,
meaning that it has high potential for abuse, but can be
administered by a doctor for legitimate medical uses,
such as local anesthetic for some eye, ear, and throat
surgeries
There are basically
two chemical forms of cocaine: the hydrochloride salt –
powder cocaine and the ‘freebase’ – smokable cocaine.
Powder Cocaine is generally sold on the street as a
fine, white crystalline powder, known as ‘coke’, ‘c’,
‘snow’, ‘candy’, or ‘blow’. Typically the cocaine sold
on the street is diluted with substances such as
cornstarch, talcum powder, and/or sugar.
How
is Cocaine Used?
It can be taken orally
– ‘chewing’, snorted through the nose, smoked, or
injected – ‘mainlining’. Injecting cocaine released the
drug directly into the bloodstream and heightens the
intensity of its effects. Injecting any drug also
carries the added risk of contracting HIV/AIDS if the
personal shares a needle with a person already infected
with HIV/AIDS. Cocaine is absorbed into the bloodstream
through nasal tissues when it is snorted. Nasal
problems, including congestion and a runny nose occur
with cocaine use. Prolonged use can cause the mucous
membrane of the nose to disintegrate. Heavy cocaine use
can sufficiently damage the nasal septum and cause it to
collapse. Smoking cocaine allows smoke that is inhaled
through the lungs to be absorbed into the bloodstream
more quickly than if it were injected. Some
users combine cocaine
powder or crack with heroin in a ‘ speedball’.

What
are the effects of Cocaine use?
There is no safe way to use cocaine. As cocaine use
continues, a tolerance often develops. This means that
a higher dose and more frequent use of cocaine are
required for the brain to register the same level of
pleasure that was experienced during the initial use.
Some recent studies have shown that even during periods
of abstinence from cocaine use, there still remains the
memory of the initial euphoria associated with cocaine
use. Triggers can set off a tremendous craving, causing
users to relapse even after long periods of abstinence.
Effects appear almost
immediately after a single dose, and disappear within a
few minutes or hours. The duration of the high depends
on how the cocaine was administered. The high from
snorting cocaine can last for 15 to 30 minutes. The
high from smoking cocaine, usually only lasts 5 to 10
minutes. Large amounts may lead to bizarre, erratic, and
violent behavior. Users often experience tremors,
muscle twitches, and paranoia. Some users report
restlessness, irritability, anxiety, and grinding of
teeth.
Some short-term
effects of cocaine use can include: Increased energy,
decreased appetite, increased heart rate and blood
pressure, constricted blood vessels, increased
temperature, dilated pupils, nosebleeds, loss of smell,
problems swallowing, hoarseness, runny nose or inflamed
nose.
Some of the most
frequent medical complications associated with cocaine
use include: Heart problems including irregular heart
rhythms and heart attacks, chest pains and respiratory
failure, strokes, seizures, abdominal pain, nausea, or
bowel gangrene due to reduced blood flow.
