EUGENE, Ore. -- Oregon athletic director Rob Mullens says the Ducks actively work to address possible illegal substance use by student-athletes.
Following a report that estimated 40 to 60 percent of the football team smoked marijuana, Mullens issued a statement Wednesday addressing the story in ESPN The Magazine, which accompanies a larger piece that looks at marijuana use among college football players.

The Oregon story is based on interviews with 19 current or former Oregon players and officials.
In response, Oregon Ducks head football coach Chip Kelly told the Associated Press Thursday afternoon that he believes the report was inaccurate.
Kelly said he doubts the Ducks would be as successful as they have been over the past few years if that many players were smoking marijuana. Oregon is 34-6 in three seasons under Kelly. This past season, the Ducks defeated Wisconsin 45-38 in the Rose Bowl.
Mullens also said earlier that that Oregon tests student-athletes to the full extent possible under Oregon state law, which prohibits random drug tests.
The school's policy allows for testing when there is a "reasonable suspicion."
Oregon's sanctions include ineligibility for half of a season following a third drug positive test, and dismissal from the team and loss of scholarship for the fourth.
Players on the team have received lots of attention for use of marijuana, some of it very unflattering, like a traffic stop where a player can be heard on a trooper's microphone 'we smoked it all.'
“Student-athlete welfare is of the utmost importance to the University of Oregon. Similar to many college campuses wrestling with the same issue, the University of Oregon actively works to address potential use of any illegal substance through a combination of education, prevention and enforcement activities. Student-athletes at the University of Oregon are tested for illegal substances to the full extent possible under existing Oregon state law, which prohibits random testing. We continue to work diligently to educate our student-athletes on the harmful impact of illegal substances. In addition, we have articulated our illegal substances policy to our student-athletes and have clearly defined sanctions for a positive test.”
