WHATIS COCAINE?
Cocaine(benzoylmethylecgonine)(INN) is a crystalline tropane
alkaloid that is obtained from
the leaves of the cocaplant.The name comes from
"coca" and the alkaloid suffix
-ine, forming cocaine.

It is a stimulant, an appetite suppressant, and a
topical anesthetic. Biologically, cocaine acts as a
serotoninnorepinephrinedopamine reuptake
inhibitor, also known as a triple reuptake inhibitor
(TRI). It is addictive because of its effect on themesolimbic reward pathway.
cocaine has pockets with both high hydrophilic and
lipophilic efficiency, violating the rule of hydrophilic-lipophilic balance. This causes it to cross the
bloodbrain barrier far better than other
psychoactive chemicals.

COCAINEINTOXICATION
It refers to the immediate effects of cocaine on the body.
Although cocaine intoxication and cocaine dependence canbe present in the same individual, they present with differentsets of symptoms.
Cocaine's primary acute effect on brain chemistry is to raisethe amount of dopamine and serotonin in the nucleus
accumbens (the pleasure center in the brain); this effectceases, due to metabolism of cocaine to inactive compoundsand particularly due to the depletion of the transmitterresources (tachyphylaxis). This can be experiencedacutely as feelings of depression, as a "crash" after the initialhigh.
Studies have shown that cocaine usage during pregnancytriggers premature laborand may lead to abruptioplacentae

HOW DOES COCAINE AFFECTTHE BRAIN?
Cocaine is a strong central nervous system
stimulant that increases levels of dopamine, a brain
chemical (or neurotransmitter) associated with
pleasure and movement, in the brains reward
circuit.
Certain brain cells, or neurons, use dopamine to
communicate. Normally, dopamine is released by a
neuron in response to a pleasurable signal (e.g.,
the smell of good food), and then recycled back intothe cell that released it, thus shutting off the signal
between neurons.

Cocaine acts by preventing the dopamine from
being recycled, causing excessive amounts of the
neurotransmitter to build up, amplifying the
message to and response of the receiving neuron,
and ultimately disrupting normal communication.
It is this excess of dopamine that is responsible for
cocaines euphoric effects. With repeated use,
cocaine can cause long-term changes in the brains
reward system and in other brain systems as well,which may eventually lead to addiction.

Cocaine in the brain: In the normal communication process,
dopamine is released by a neuron into the synapse, where it canbind to dopamine receptors on neighboring neurons. Normally,
dopamine is then recycled back into the transmitting neuron by a
specialized protein called the dopamine transporter. If cocaine is
present, it attaches to the dopamine transporter and blocks the
normal recycling process, resulting in a buildup of dopamine in the
synapse, which contributes to the pleasurable effects of cocaine.

hemoptysis, bronchospasm, pruritus, fever, diffusealveolar infiltrates without effusions, pulmonary and
systemic eosinophilia, chest pain, lung trauma, sorethroat, asthma, hoarse voice, dyspnea (shortness ofbreath), and an aching, flu-like syndrome., parkinsonsdiseases.
Gastrointestinal complications such as abdominal painand nausea. A common but untrue belief is that the smoking
of cocaine chemically breaks down tooth enamel and causestooth decay. However, cocaine does often cause involuntarytooth grinding, known as bruxism, which can deterioratetooth enamel and lead to gingivitis.

Chronic intranasal usage can degrade the cartilageseparating the nostrils (the septum nasi), leadingeventually to its complete disappearance.
Cocaine may also greatly increase this risk ofdeveloping rare autoimmune or connective tissuediseases such as lupus, Goodpasture's disease,vasculitis, glomerulonephritis, StevensJohnsonsyndrome and other diseases. It can also cause a widearray ofkidney diseases and renal failure.
Cocaine misuse doubles both the risks ofhemorrhagicand ischemic strokes, as well as increases the risk ofotherinfarctions, such as myocardial infarction.
