Early Risk Factors for Daily Cannabis Use in Young Adults
Abstract
Objectives: Daily cannabis use can portend problematic use or dependence. We aimed to identify early risk factors for daily cannabis use in young adults.
Methods: Data were available in a longitudinal investigation of 1294 grade 7 students age 12 to 13 years at inception recruited in 10 secondary schools in Montreal, Canada, in 1999. Data on daily cannabis use were collected in mailed self-report questionnaires from 878 participants (67.9% of 1294) at age 20. The associations between each of 23 potential risk factors measured in grade 7 and daily cannabis use at age 20 were modeled using logistic regression.
Results: At age 20, 44% of participants reported past-year cannabis use; 10% reported daily use. Older age; male sex; higher levels of family stress and other stress; use of alcohol, cigarettes, and other tobacco products; parent(s), sibling(s), and friend(s) smoke cigarettes; higher body mass index; higher impulsivity and novelty seeking; and lower self-esteem increased the odds of daily cannabis use.
Conclusions: Children at risk of daily cannabis use as young adults can be identified early. They may benefit from early intervention to prevent problematic cannabis use.
Objectifs:: L’utilisation quotidienne de cannabis peut présager une utilisation problématique ou une dépendance. Nous cherchions à identifier les facteurs de risque précoces de l’utilisation quotidienne de cannabis chez les jeunes adultes.
Méthodes:: Les données provenaient d’une enquête longitudinale menée auprès de 1294 élèves de 7e année, âgés de 12-13 ans au départ et recrutés dans 10 écoles secondaires de Montréal, Canada en 1999. Les données sur l’utilisation quotidienne de cannabis ont été recueillies dans des questionnaires postaux auto-déclarés par 878 participants (67,9% de 1294) à l’âge de 20 ans. Les associations entre chacun des 23 facteurs de risque potentiels mesurés en 7e année et l’utilisation quotidienne de cannabis à l’âge de 20 ans ont été modélisées à l’aide de la régression logistique.
Résultats:: À l’âge de 20 ans, 44% des participants déclaraient une utilisation de cannabis l’année précédente; 10% déclaraient une utilisation quotidienne. L’âge plus avancé, le sexe masculin, des niveaux plus élevés de stress familial et autre, l’utilisation d’alcool, de cigarettes et d’autres produits du tabac, le ou les parents, frères et sœurs et amis qui fument la cigarette, un IMC plus élevé, une impulsivité et une recherche de nouveauté élevées, et une faible estime de soi augmentaient la probabilité d’une utilisation quotidienne de cannabis.
Conclusions:: Les enfants à risque d’une utilisation quotidienne de cannabis lorsqu’ils deviennent jeunes adultes peuvent être identifiés tôt. Ils peuvent bénéficier d’une intervention précoce afin de prévenir une utilisation de cannabis problématique.
