Cocaine
Addiction
Cocaine addiction can occur
very quickly and be very difficult to break. Animal studies have shown that
animals will work very hard (press a bar over 10,000 times) for a single injection
of cocaine, choose cocaine over food and water, and take cocaine even when this
behavior is punished. Animals must have their access to cocaine limited in order
not to take toxic or even lethal doses. People addicted to cocaine behave similarly.
They will go to great lengths to get cocaine and continue to take it even when
it hurts their school or job performance and their relationships with loved
ones.
Attempts to stop using the
drugs can fail simply because the resulting depression can be overwhelming,
causing the addict to use more cocaine in an attempt to overcome his depression.
This overpowering addiction can cause the addict to do anything to get cocaine.
Recent studies on cocaine and addiction have shown that, during periods of abstinence
from cocaine use, the memory of the euphoria associated with cocaine, or mere
exposure to cues associated with cocaine use, can trigger tremendous craving
and relapse to cocaine, even after long periods of abstinence.
Researchers have found that
cocaine stimulates the brain's reward system inducing an even greater feeling
of pleasure than natural functions. In turn, its influence on the reward circuit
can lead a user to bypass survival activities and repeat drug use. Chronic cocaine
use can lead to a cocaine addiction and in some cases damage the brain and other
organs. An addict will continue to use cocaine even when faced with adverse
consequences. Cocaine and crack cocaine continue to be the most frequently mentioned
illicit substance in U.S. emergency departments (ED), present in 30% of ED drug
episodes during 2001. From 2000 to 2001, the number of ED cocaine mentions increased
ten percent from 174,881 in 2000 to 193,034 in 2001.
"Crack" is the
street name given to cocaine that has been processed from cocaine hydrochloride
to a free base for smoking. Crack cocaine looks like white to tan pellets or
chunks that resemble rock salt or soap. 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. Research studies regarding crack and addiction,
has shown crack to have more addictive properties than cocaine. This is due
to its chemical makeup and method of use.
