The hidden drug abuse in a stratified sample of a year cohort born in 1953 was studied by measuring the difference between drug abuse stated in interviews and registered in public health and social welfare files in 1968, 1973 and 1976. Among men who had stated high-frequency drug use in a school questionnaire in 1968 hidden drug abuse comprised two thirds of the total abuse, among women from the same group one half. In groups with lower degrees of abuse hidden drug abuse was 70-90% of the total abuse. Intravenous abuse was mostly known to public health and social welfare authorities. When trying to estimate the total number of drug abusers in an area there is reason to at least double the figures presented in case-finding studies.
通过测量1968年、1973年和1976年访谈中所述药物滥用情况与公共卫生和社会福利档案中登记的药物滥用情况之间的差异，对1953年出生的一年队列分层样本中的隐性药物滥用情况进行了研究。在1968年学校调查问卷中自述有高频药物使用的男性中，隐性药物滥用占总滥用情况的三分之二，在同一组女性中占一半。在滥用程度较低的群体中，隐性药物滥用占总滥用情况的70-90%。静脉注射滥用大多为公共卫生和社会福利当局所知。在试图估计一个地区药物滥用者的总数时，有理由至少将病例发现研究中给出的数字翻倍。
