Abstract
Changes in reported levels of drug use over 1 yr are described in 2 sets of pupils, including changes in drug use reported between a 1973 4th form group and a matched 5th form group from the same schools 1 yr later (follow-up study); and differences in reported levels of use between the 1973 4th form and a matched group of 1974 4th forms from the same schools (trend study). There was no evidence of any substantial general increase or decrease in familiarity with drugs in the schools studied during the 1-yr study period.
