An estimated 28 percent of high school seniors reported riding in a car in the past two weeks with a driver who had used drugs or alcohol, or said they had driven after using drugs or alcohol themselves, researchers found.

The confidential questionnaires did not ask seniors about the amount of marijuana smoked, or who they got in the car with, like a parent or friends. Another problem confounding researchers is how to determine how much marijuana is too much; there is no comparable DUI standard.
