Patterns of drug use among adolescents: The past decade

In recent years investigators have examined patterns of drug use among various populations. None, however, have examined the changes in drug patterns over time. The present study analyzed changes in patterns of drug use among a population of drug-using adolescent students in Ontario (Canada). Three cross-sectional surveys conducted in 1968, 1977 and 1985, which sampled students in grades 7, 9, 11 and 13 (ranging in age from 12 to 20 years), were employed.Using eight substance types as measures (cannabis, barbiturates, stimulants, tranquillizers, inhalants, LSD, heroin and others), four general patterns were constructed: single-drug psychotherapeutic users; exclusive cannabis users; and multiple-illicit. The findings indicated the following: (i) a significant decrease in the representation of both exclusive and multiple psychotherapeutic users between 1968 and 1977; (ii) a significant increase in exclusive cannabis users between 1968 and 1977, and following this a decline into 1985; and (iii) a significant increase in multiple illicit users between 1968 and 1977. In all a major shift from a psychotherapeutic-illicit dichotomy to an overwhelming illicit pattern has occured during the past decade.drug use polydrug use

The Impact of Depression on Driver Performance

This study reviews the existing literature concerning the association between depression and driver safety. Despite its increasing prevalence and its disabling impact on the world’s population, there is surprisingly little research examining the impact of depressive disorders on driver performance. The review begins by examining the early studies of drivers deemed “mentally ill” and the subsequent epidemiological literature including case–control and prospective cohort studies of depressed drivers. The review also examines the more recent experimental investigations of depression and driver performance that have relied on naturalistic measurements and advanced driving simulation. The review concludes with a discussion of relevant issues (e.g., the impact of antidepressants on driver performance, suicide by driving), public policy implications of the research, and future research directions
