Drug addiction is always been complex problems. The study found that drug addiction can be caused by heredity. The scientists found abnormalities in the brain of drug addicts and siblings who are not addicts.
"Substance abuse is known can run into families. Having a family member who is addicted to drugs increase the risk of addiction to 8-10 per cent compared to the average person. But we have yet to find genes that influence this addiction," said Tapi Karen Esche at University of Cambridge in England as VOA News reported on Tuesday (03/13/2012).
Esche team used MRI brain scans to photograph the brains of cocaine addicts and their siblings who are not addicts. Brain scans showed the same abnormalities in the pre-frontal and striatal brain. This pattern was not found in volunteers who did not have an addiction and drug addict brothers.
