(Newser) – A newly discovered gene can improve your chances of getting hooked on cocaine, scientists said today. A study of 670 cocaine addicts and 700 non-users found that addicts were 25% more likely to have the gene variant. The discovery could lead to DNA screenings for those likely to try the drug, scientists say. "You can certainly use this as a vulnerability marker for cocaine addiction," an author of the study told the Guardian.
