This research focuses on the analysis of cannabis consumption amongst young people, explaining this phenomenon by way of analysing the differences between cannabis smokers and non-smokers in order to shed light on whether cannabis is linked to specific leisure activities, and, moreover, whether it is connected to the intensity and variety of…

Since 1975 the Monitoring the Future (MTF) survey has measured drug, alcohol, and cigarette use and related attitudes among adolescent students nationwide. Survey participants report their drug use behaviors across three time periods: lifetime, past year, and past month; for some drugs, daily use is also reported. Initially, the survey included…

This study investigated the influence of age of alcohol initiation on current alcohol use and alcohol-related problems in a diverse college student sample. Participants (N = 214) completed a questionnaire assessing attitudes, beliefs, and behavioral habits regarding alcohol and other drugs. Early alcohol initiation (alcohol use before age 15) was…

This study examined in a random community-based sample of 664 12-19-year-olds, the relation of subjective experience of age (SEA) with chronological age, dating experience, sexual activity, and substance use. The results revealed a positive linear relation between SEA and chronological age: individuals who were chronologically older felt…

A decade ago we published a book reporting an extensive analysis of nationwide panel data from the Monitoring the Future (MTF) project showing impacts of post-high school experiences on substance use (Bachman, Wadsworth, O'Malley, Johnston, & Schulenberg, 1997).

Examined interactive nature of age in predicting alcohol, marijuana, and drug use among 435 seventh and eleventh graders. Found statistically significant interaction terms for age with peer and social control factors for each type of usage. Findings suggest that many factors commonly associated with adolescent usage may be conditioned by age.…

Analyzed self-reported history of parasuicide with respect to use of intoxicants in national sample of 12,000 Norweigan adolescents. Proportion of parasuicides was 8.3%, being higher among girls and those living without both parents; and rate increased with age, use of intoxicants, depression, and loneliness.
