This study was designed to provide 2 types of information simultaneously. First, the authors compared in terms of time and cost the value of a mailed questionnaire and a 'face to face' interview. Statistical tests show that the 2 types of information gathering techniques yield similar results. The 'face to face' interview approach was more time consuming (approximately 45 min per session) and was 6 times more costly than the mailed questionnaire. Second, they measured the patterns and levels of drug use among undergraduates on a southern university campus. Student use of marijuana, barbiturates, amphetamines and hallucinogens was studied.
