Gene variants associated with alcohol dependence are still associated with the risk of psychological disorders and other drug use, a total study of more than 50,000 people published in November. 26 in the journal Nature Neuroscience found.

“Was a genetic link as with other psychological disorders these as depression, for example, and with the introduction of tobacco and other drugs these as cannabis,”said co-author-correspondent Joel Gelernter, doctor Foundation of psychiatry and a doctor of genetics and neurology at Yale. "As we study a larger number of people, we expect that we will be able to qualify, at least to some extent, this correlation, or the artel risk, explained by alcoholism, and how much is possible to be a consequence of these other disorders.”

Multi-institutional studies have approved, in fact, that the risk of alcohol dependence is considered the result of many genetic varieties, and since the gene with the role of alcohol metabolism plays a significant role in people like the Euro, for example, and of African origin.
