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 17 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 drug use, as found in this and similar surveys, can be accepted with reasonable confidence.
1981年，通过对加拿大安大略省4306名5、7、9、11和13年级学生的分层概率样本进行自我报告的匿名问卷调查，对药物使用情况进行了调查。结果发现药物使用存在一致模式，包括海洛因等使用频率较低的非法药物。在药物使用流行率较高的学校年级中，药物使用的一致性更为明显。药物使用分布不均，集中在所有学校和地理区域中相对较小的一部分。在所研究的17类物质中，使用频率最低的物质分布最为集中。该研究表明，学生对药物使用情况普遍不存在误报，这证实了其他研究人员的发现，即自我报告的药物使用的可靠性和有效性问题似乎更多地与回忆和自我定义药物使用的困难有关，而不是故意误报。文章中提供的证据表明，在本次及类似调查中发现的自我报告的学生药物使用数据，可以有合理的信心被接受。
