^aContinued smoking is one who smoked at Waves I and II. A current smoker at Wave II is one who smoked on at least 1 of the past 30 days. ^bAt Wave I, a current smoker was one who said they had smoked on at least 1 of the past 30 days. ^cCurrent ST users were those who used chewing tobacco or snuff on at least one of the past 30 days at Wave I. ^d A binge drinker is one who drank five or more drinks in a row, at least once in the past year, at Wave I. A nonbinge drinker is one who drank at least once during the past year, but did not drink five or more drinks in a row during the past year, at Wave I. ^eRespondents were asked at Wave I, “On a scale of 1 to 5, where 1 is low and 5 is high, how likely is it that you will go to college?” This is the average of the responses.
