A survey of drug use, carried out in 1981 by means of a self-reported anonymous questionnaire administered to a stratified probability sample of 4,306 school students in grades 5, 7, 9, 11 and 13 in Ontario, Canada, found consistent patterns in the use of drugs, including infrequently used illegal drugs such as heroin. Consistency of drug use was more apparent in the school grades with greater prevalence rates of drug use. Drug use was unevenly distributed and was localized within a relatively small proportion of all schools and geographical areas covered. Among the l7 categories of substances studied, the least frequently used substances were most localized. The study shows a general absence of misrepresentation of drug use by students, which corroborates findings reported by other researchers who have indicated that the problems of reliability and validity of self reported drug use appear to be more related to difficulties in recalling and self-defining drug use than to its deliberate misrepresentation. The evidence presented in the article suggests that data on self-reported student d rug use, as found in this and similar surveys, can be accepted with reasonable confidence.
