Parental influences on marijuana use in emerging adulthood

Area of Science:

• Psychology
• Sociology
• Public Health

Background:

• Emerging adulthood (ages 19-22) is a critical developmental period characterized by significant life transitions and identity exploration.
• Marijuana use patterns during emerging adulthood are influenced by various psychosocial factors, including family dynamics.
• Understanding the interplay between parental relationships and adolescent substance use is crucial for developing effective prevention and intervention strategies.

Purpose of the Study:

• To investigate the relationship between parental relationship qualities and marijuana use trajectories in emerging adults (EAs).
• To identify specific aspects of parent-child relationships that predict different patterns of marijuana use in EAs.
• To explore the role of parental knowledge and communication in EA marijuana use.

Main Methods:

• Utilized parent-report and child-report data from a diverse sample of 470 EAs and their parents in the Pacific Northwest.
• Employed Latent Class Growth Analysis (LCGA) to model marijuana use trajectories.
• Conducted risk factor analyses to examine the association between parental relationship qualities and EA marijuana use group membership.

Main Results:

• Lower family cohesion and poorer parent-child communication quality predicted higher marijuana use groups.
• Infrequent parent-child communication was associated with higher marijuana use.
• Parental awareness of EA marijuana use, particularly when congruent or underestimating use, predicted higher use groups compared to low-to-non users.

Conclusions:

• Warm, supportive parent-child relationships are associated with healthier decision-making regarding marijuana use in emerging adults.
• Parental awareness of EA marijuana use, without excessive focus on perceived risk, may be beneficial.
• Interventions promoting positive parent-child communication and supportive family environments can influence EA substance use behaviors.
