FILE - in this Jan. 1, 2015, file photo, Oregon wide receiver Darren Carrington, front, scores under pressure from Florida State defensive back Trey Marshall during the Rose Bowl NCAA college football playoff semifinal in Pasadena, Calif. Carrington and teammate Ayele Forde were left behind for the college football title game after positive drug tests.At least one of those was for marijuana. Shortly after that, an NCAA committee recommended an overhaul of some facets of the drug-testing policy--most notably that marijuana testing on the national level be scrapped in favor of education and intervention. Alcohol and narcotics would be added to the list of recreational drugs that need to be more closely monitored. (AP Photo/Jae C. Hong, File) less
