Cocaine comes from the leaves
of the coca plant that grows in the Andes Mountains in South America. Many
indigenous tribes in this region continue to chew coca leaves to produce a mild,
stimulating feeling.
Scientists isolated cocaine
from coca leaves shortly before 1860. Until the start of the 20th century, this
new "wonder drug" could be found in countless medicines to treat a variety of
ailments. It was also included in many of the popular health tonics of the day,
including Coca-Cola.
Cocaine hydrochloride (HCL)
is a fine white powder, bitter to the taste. When inhaled or injected, it causes
a numbing effect. "Crack" is a smokeable form of cocaine made into small lumps
or "rocks." Crack is made by processing cocaine HCL with ammonia or sodium
bicarbonate (baking soda) and water and heated to free the cocaine alkaloid
"base" from the salt (hydrochloride). This process enables the drug to burn
efficiently, providing more cocaine-containing smoke. The term "crack" refers to
the cracking sound when the mixture is smoked.
Cocaine increases stamina,
alertness, heart rate, and energy, and temporarily decreases fatigue, causing
users to feel exhilarated, euphoric, and confident. The duration of cocaine’s
effects depends on the route of administration. The high from snorting may last
15-30 minutes. Smoking crack delivers large quantities of the drug to the lungs,
producing effects comparable to intravenous injection. These effects are felt
almost immediately after smoking, are very intense, and last 5-10 minutes.
Over time, many people who
use cocaine on a daily basis develop a tolerance to the drug, meaning they will
need more and more to get the same initial effect. This, combined with the fact
that cocaine and crack are so short acting, often leads the user to compulsively
chase after the initial high.
Strokes, seizures, and heart
attacks, although rare, have been reported. Individuals with a known (or
unknown) heart condition are most at risk. Chronic, heavy use of cocaine/crack
can result in weight loss, sexual problems, disordered thinking, extreme mood
swings, paranoia, aggression, and psychosis. Many such chronic, heavy users
become physically run down, which leaves them susceptible to illness and
depression.
Although snorting cocaine poses less risk than smoking or
injecting, repeated sniffing may still damage the membranes of the nose. Smoking
cocaine/crack can damage the lungs, as well as leading to more compulsive use,
due to its faster absorption. Injecting cocaine poses a number of serious risks.
In addition to impuri-ties delivered directly into the blood stream, if needles
or other injection materials are shared, users are at greater risk for
transmitting or acquiring HIV infection, AIDS or Hepatitis B and C.
Many myths surround crack use. Despite media reports
claiming crack to be addictive with a single use, the best data, from
government-sponsored surveys, have consistently shown that less than one out of
four people who ever tried the drug used it more than once.
Media stories of a "crack baby" epidemic, which began to
appear in the late 1980s, are now considered greatly exaggerated. Research now
indicates that other factors, such as poverty, are responsible for many of the
ills previously thought to be associated with crack use. Criminal penalties for
possession and sale of powder cocaine are severe. Much higher penalties exist
for possession and sale of crack, despite the fact that, pharmacologically, they
are the same drug. Simple possession of five grams of crack cocaine yields a
five-year mandatory minimum sentence for a first offense; it takes 500 grams of
powder cocaine to prompt the same sentence.
