It has become commonplace for people who are overweight to attribute their waistline to their DNA. Now, celebrities caught snorting cocaine might also be able to blame their parents.
Scientists reported yesterday the discovery of a gene that increases the chances of becoming hooked on the drug Addicts were 25% more likely to carry the gene variant than people who did not use cocaine, a study found.
The discovery is unlikely to lead to a treatment for cocaine addicts, but scientists hope it could be used to screen for those most likely to have problems kicking the habit if they ever try the drug.
“If you are a carrier of this gene variant, the likelihood of getting addicted to cocaine is higher,” said Rainer Spanagel, a professor of psychopharmacology at the Central Institute of Mental Health in Mannheim, Germany, who led the study. “You can certainly use this as a vulnerability marker for cocaine addiction.”
