Scientists have uncovered evidence that several of the common genes are actually tied to alcohol, cocaine and nicotine addictions, a major breakthrough they claim will facilitate the effective treatment of addicts.
Co-scientist Ming Li of Virginia University said: "We have found several genes are linked with multiple addictions. So, we are narrowing the scope to specific genetic targets. "Once researchers can pinpoint exact genetic variants and molecular mechanisms, then we can create more effective, even personalised, treatments for individuals addicted to a variety of substances."
In their study, the scientists have revealed a summary of specific genomic locations on 11 chromosomes where addictions to alcohol, cannabis, cocaine, heroin, nicotine and opoids are clustered together. "The comparison of peaks for addictions to multiple substances on certain chromosomal locations confirms genetic vulnerability to different substances overlaps, in part," Li was quoted by the media as saying.
