A gene associated with red hair and fair skin may also be responsible for how females respond to painkillers, according to a study conducted by lead researcher Jeffrey Mogil, a McGill University psychology professor, and collaborators in the United States. Results of their study are to be released today in Proceedings of the National Academy of Sciences of the USA (article #03-0053). “While we believe pain is the same in all women of all hair colours,” explained Mogil, “our study shows women with red hair respond better to the pain-killing drug we tested than anyone else — including men.”
