Early adolescent drinking and cannabis use predicts later sleep-quality problems

Area of Science:

• Adolescent development
• Sleep science
• Substance use research

Background:

• Adolescence involves biopsychosocial changes affecting the sleep-wake system.
• Substance use, including alcohol and cannabis, increases during early adolescence.
• Limited research exists on the link between evolving substance use and adolescent sleep issues.

Purpose of the Study:

• To investigate the association between changes in alcohol and cannabis use patterns and sleep quality in adolescents.
• To identify specific aspects of alcohol and cannabis consumption related to sleep problems.

Main Methods:

• Longitudinal study of 245 adolescents, starting at age 12.
• Baseline assessment of alcohol and cannabis use.
• Follow-up assessments at ages 14, 16, and 18, with sleep quality measured at age 18.

Main Results:

• Earlier substance use was associated with poorer sleep quality at age 18.
• Heavy episodic drinking over time correlated with worse sleep.
• Lifetime alcohol use at age 18 and recent cannabis use at age 18 were linked to poor sleep quality.

Conclusions:

• Specific patterns of adolescent alcohol and cannabis consumption are associated with poor sleep quality.
• Findings highlight the impact of substance use on adolescent sleep health.
• Further research into adolescent substance use and sleep is warranted.
