Linkage Between Gene and Addiction

The news that scientists report, in three papers in two journals today, that they have found evidence of genes that promote addiction to tobacco and thus to lung cancer, adds to evidence that tobacco. alcohol and narcotic addictions all seem to have genetic bases. However, it will take years before this research translates into effective treatment and prevention. In the meantime it could bring better understanding to policies that try inhibit exposure to, and treatment for, addicton. There is little evidence that punishment changes addictive behaviors.. Current punishment of addicts is probably counterproductive and should change we learn more about the role genes play in addiction.
