1. Objectifs

Intentions :
«First, [the authors] examined whether parental cannabis use is associated with incident cannabis use among adolescent off-spring in high school. Second, [they] investigated whether cannabis use by mothers or fathers is associated with cannabis use in young-adult offspring.» (p. 143-143)

2. Méthode

Échantillon/Matériau :
Les auteurs ont mobilisé deux études longitudinales ayant été produites à Montréal. Le sous-échantillon provenant de l’étude AdoQuest est composé de 1048 parents et de leurs enfants d’âge scolaire. Le sous-échantillon provenant de l’étude Nicotine Dependance in Teens (NDIT) est composé de 584 participants et de leurs parents (542 mères et 438 pères).

Instruments :
Questionnaires

Type de traitement des données :
Analyse statistique

3. Résumé

«AdoQuest data provide evidence that children whose parents use cannabis are 1.8 times more likely to initiate cannabis use, and NDIT data suggest that young-adult offspring whose mothers or fathers use cannabis are more likely to report past-year cannabis use. [Also, there] was no indication in the NDIT study data that cannabis use by mothers or fathers had a differential effect on offspring cannabis use. […] Parental use could influence offspring use directly through ease of access, increased visibility of cannabis use, role modeling, or transmission of pro-cannabis norms. [Moreover, the results] highlight a major intervention opportunity in family healthcare settings. After legalization, screening for parental cannabis use will become even more important, although a distinction will need to be made between medicinal and recreational use. […] The heightened potency of today’s cannabis should be a component of teaching because parental experiences with cannabis may not translate to today’s cannabis. Finally, although parental abstinence may be a desired goal in terms of preventing offspring uptake, a harm reduction approach also may be relevant. Clear messaging on how parental use increases the risk for early use and addiction in offspring may help, as may suggestions about using cannabis recreationally in moderation and away from offspring. […] In conclusion, parental cannabis use is associated with cannabis initiation in adolescents and with weekly and daily use in young adult offspring.» (p. 146)
