Past 30-Day Cannabis Use by Perception of Risk and Age Group: Implications for Prevention

Area of Science:

• Public Health
• Substance Use Research
• Adolescent Health

Background:

• Cannabis use is a significant public health issue in the U.S.
• The relationship between perceived risk and cannabis use is established for various age groups.
• Understanding age-specific risk perception is crucial for effective prevention strategies.

Purpose of the Study:

• To investigate the interaction between perceived risk and age on past 30-day cannabis use.
• To identify specific age groups where risk perception most influences cannabis consumption.
• To provide data for targeted public health interventions regarding cannabis use.

Main Methods:

• Secondary data analysis of the 2021 National Survey on Drug Use and Health (NSDUH).
• Utilized a nationally representative sample of U.S. individuals aged 12 and older (N = 58,034).
• Employed binary logistic regression, accounting for complex survey sampling elements.

Main Results:

• A significant interaction was found between age and perceived risk of cannabis use.
• The probability of cannabis use increased most sharply between ages 12-17 and 18-25 for those with no/low risk perception.
• This highlights a critical developmental period for cannabis use initiation influenced by risk assessment.

Conclusions:

• Interventions addressing perceived cannabis risk in adolescents are vital for preventing later use.
• Results pinpoint age groups with higher cannabis use probability based on risk perception.
• This population-level analysis offers direct insights for evidence-based preventive strategies.
