A Single Line Of Cocaine Can Cause Permanent Changes To The Brain


Just one line of cocaine is all it takes for a recovering addict's brain to become significantly more vulnerable to a relapse.

A team led by the University of East Anglia's Dr. Peter McCormick conducted a recent experiment on rats to determine what causes recovering cocaine addicts to begin using again, Daily Mail reports.

Dr. McCormick wrote,

According to Medical Daily, the researchers discovered that cocaine use disrupts the communication between two proteins in the brain involved with reward and stress.

This makes it much easier for a user or former user to become so overwhelmed by a stressful situation that cocaine appears to be the only solution.

Such situations include any mentally taxing activity or even seeing someone use cocaine on television.

Dr. McCormick declared,

The researchers talk about this effect on recovering addicts but say nothing about the effects on someone using cocaine for the very first time.

Additional experimentation found that repairing the link between these two molecules restores a user's self-control and reduces the likelihood of relapsing under stress.

Researchers suggested a medication given to recovering addicts should serve this function.

Dr. McCormick added,

This study was originally published in The Journal of Neuroscience.
