Cocaine addiction is caused by the effect of cocaine on the brain as is seen with other drugs. It powerfully stimulates the central nervous system and leads to intense feelings of euphoria and grandiosity in users. Dopamine, the brain’s pleasure chemical is increased. Dopamine is usually released because of potential compensation. The feelings derived from sex, eating food or doing other exciting activities are the cause of this. It goes back into which ever cell it was released from after its release. The dopamine is prevented from being recycled by the cocaine which interrupts regular brain communication by amplifying the dopamine signal. The cause of the euphoric high from cocaine is this flood of dopamine.
A tolerance to cocaine may be established after abusing it for long and they may not have the same high which they got from it before. There is therefore an increased risk of other unfavorable psychological and physical side effects from cocaine usage. There is an increased need for cocaine addiction rehab as the tolerance level grows.
