Addiction experts at the University of Virginia Health System and the University of Michigan have found that several genes are linked with multiple addictions. Ming Li, Ph.D., professor of psychiatry and neurobehavioral sciences at the UVA School of Medicine said, "We're narrowing the scope to specific genetic targets. Once researchers can pinpoint exact genetic variants and molecular mechanisms, then we can create much more effective, even personalized, treatments for individuals addicted to a variety of substances."This discovery could have huge ramifications for those suffering from addiction. It could also be used to identify those who would be more susceptible to addictions in the future.
The study showed "a summary of specific genomic locations on 11 chromosomes where addictions to alcohol, cannabis, cocaine, heroin, nicotine and opoids are clustered together." This means that right now we do not know which genes encode for which addiction however we know that someone with addictive behavior is most likely to have many addictive genes for many different substances. By using this information we can greatly improve our understanding of addiction and find new and better ways to treat those suffering from it.
