COCAINE: OLDEST AND STILL POPULAR STIMULANT DRUG

Cocaine is the most potent stimulant of natural origin and is one of
the oldest identified drugs.

The pure chemical, cocaine hydrochloride, has been an abused substance
for more than 100 years. The coca leaf, which is the source of
cocaine, has been ingested for thousands of years.

Pure cocaine was first extracted from the leaf of the coca bush, which
grows primarily in Peru and Bolivia.

In the early 1900s, cocaine became the main stimulant drug used in
tonics and elixirs that were developed to treat a wide variety if illnesses.

Today, cocaine is rarely used medically because of its high potential
for abuse and addiction.

There are two forms of cocaine: powered cocaine and crack
(freebase).

The powered, hydrochloride salt form of cocaine can be snorted or
dissolved in water and injected. Crack (freebase) is cocaine that has
not been neutralized by an acid to make the hydrochloride salt.

Cocaine is generally sold on the street as fine, white, crystalline
powder. Street dealers generally dilute pure cocaine with inert
substances such as lactose, mannitol cornstarch, and/or sugar, or with
other stimulants.

The purity levels of cocaine have varied over the years but are higher
now than in the 1970s. The street level purity would be at least 60
per cent and higher.

Signs of cocaine use include blurred vision, dilated pupils, tremors
and twitching, chest pain or pressure, and fever.

In general, cocaine use causes an elevated heart rate, elevated blood
pressure, elevated respiratory rate, decreased appetite, aggression,
paranoia, depression, and irritability. At high doses, cocaine may
produce hallucinations or delusions.

Long-term effects of use include a strong psychological dependence and
varying degrees of physical tolerance. Eating disorders, malnutrition,
impotence, seizures, strokes, severe withdrawal symptoms, and
permanent damage to the nasal passage are also consequences of cocaine
use.

Cocaine-related deaths are often attributed to cardiac arrest or
seizures followed by respiratory arrest.

Research has revealed a potentially dangerous interaction between
cocaine and alcohol.

Taken in combination, the two drugs are converted by the body to coca
ethylene. Coca ethylene has a longer duration of action in the brain
and is more toxic than either drug alone.

While more research needs to be done, it is noteworthy that the
mixture of cocaine and alcohol is the most common two-drug combination
that results in the drug-related death.
