Crack
and Cocaine
Cocaine is a powerfully addictive drug of abuse. Once having tried cocaine,
an individual cannot predict or control the extent to which he or she
will continue to use the drug.
The major routes of administration of cocaine are sniffing or snorting,
injecting, and smoking (including free-base and crack cocaine). Snorting
is the process of inhaling cocaine powder through the nose where it is
absorbed into the bloodstream through the nasal tissues. Injecting is
the act of using a needle to release the drug directly into the bloodstream.
Smoking involves inhaling cocaine vapor or smoke into the lungs where
absorption into the bloodstream is as rapid as by injection.
"
Crack" is the street name given to cocaine that has been processed
from cocaine hydrochloride to a free base for smoking. Rather than requiring
the more volatile method of processing cocaine using ether, crack cocaine
is processed with ammonia or sodium bicarbonate (baking soda) and water
and heated to remove the hydrochloride, thus producing a form of cocaine
that can be smoked. The term "crack" refers to the crackling
sound heard when the mixture is smoked (heated), presumably from the
sodium bicarbonate.

There is
great risk whether cocaine is ingested by inhalation (snorting),
injection, or smoking. It appears that compulsive cocaine use may
develop even more rapidly if the substance is smoked rather than
snorted. Smoking allows extremely high doses of cocaine to reach
the brain very quickly and brings an intense and immediate high.
The injecting drug user is at risk for transmitting or acquiring
HIV infection/AIDS if needles or other injection equipment are
shared. |
Health Hazards
Cocaine is a
strong central nervous system stimulant that interferes with the reabsorption
process of dopamine, a chemical messenger associated
with pleasure and movement. Dopamine is released as part of the brain's
reward system and is involved in the high that characterizes cocaine
consumption.
Physical effects
of cocaine use include constricted peripheral blood vessels, dilated
pupils, and increased temperature, heart rate,
and blood pressure. The duration of cocaine's immediate euphoric
effects, which
include hyper-stimulation, reduced fatigue, and mental clarity,
depends on the route of administration. The faster the absorption,
the more intense
the high. On the other hand, the faster the absorption, the shorter
the duration of action. The high from snorting may last 15 to
30 minutes,
while that from smoking may last 5 to 10 minutes. Increased use
can reduce the period of stimulation.
Some users of
cocaine report feelings of restlessness, irritability, and anxiety.
An appreciable tolerance to the high may be developed,
and many addicts report that they seek but fail to achieve as
much pleasure
as they did from their first exposure. Scientific evidence suggests
that the powerful neuropsychologic reinforcing property of cocaine
is responsible
for an individual's continued use, despite harmful physical and
social consequences. In rare instances, sudden death can occur
on the first
use of cocaine or unexpectedly thereafter. However, there is
no way to determine who is prone to sudden death.
| High
doses of cocaine and/or prolonged use can trigger paranoia. Smoking
crack cocaine can produce a particularly aggressive paranoid behavior
in users. When addicted individuals stop using cocaine, they often
become depressed. This also may lead to further cocaine use to
alleviate depression. Prolonged cocaine snorting can result in
ulceration of the mucous membrane of the nose and can damage the
nasal septum enough to cause it to collapse. Cocaine-related deaths
are often a result of cardiac arrest or seizures followed by respiratory
arrest. |

Added Danger:
Cocaethylene
When people mix
cocaine and alcohol consumption, they are compounding the danger each
drug poses and unknowingly forming a complex
chemical experiment within their bodies. NIDA-funded researchers
have found
that the human liver combines cocaine and alcohol and manufactures
a third
substance, cocaethylene, that intensifies cocaine's euphoric
effects, while possibly increasing the risk of sudden death.
Alcohol
plus cocaine equals cocaethylene equals potential sudden death!!!
