cocaine addiction solution:
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 brain’s 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 into the cell that released it, thus shutting off the signal between neurons.
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
Cocaine’s euphoric effects. With repeated use, cocaine can cause long-term changes in the brain’s
reward system and in other brain systems as well, which may eventually lead to addiction. With repeated use, tolerance to the cocaine high also often develops. Many cocaine abusers and cocaine addicts report
that they seek but fail to achieve as much pleasure as they did from their first exposure.
Some users and cocaine addicts will increase their dose in an attempt to intensify and prolong the euphoria, but this can also increase the risk of adverse psychological or physiological effects.
