Genetic trait could triple odds of whites susceptibility to heavy cocaine abuse
ScienceDaily (2010-12-20) Nearly one in five whites could carry a genetic variant that substantially increases their odds of being susceptible to severe cocaine abuse, according to new research. This genetic variant, characterized by one or both of two tiny gene mutations, alters the brains response to specific chemical signals. In the study, the variant was associated with a more than threefold increase in the odds that carriers will be susceptible to severe cocaine abuse leading to fatal overdosing, compared to non-carriers. > read full article
