Polydrug use by high-school students: involvement and correlates.

Area of Science:

• Psychology
• Sociology
• Criminology

Background:

• Polydrug use among adolescents is a significant public health concern.
• Understanding the predictors of polydrug involvement is crucial for developing effective interventions.
• Previous research has explored various factors, but a comprehensive analysis of psychological and sociocultural predictors is needed.

Purpose of the Study:

• To identify distinct types of polydrug users within a high-school population.
• To determine the relationship between background characteristics, attitudes, and polydrug involvement.
• To investigate the predictive power of personal motivations versus sociocultural factors on polydrug use.

Main Methods:

• Hierarchical cluster analysis of drug use frequency (marijuana, stimulants, depressants, hallucinogens, solvents, opiates) in 273 high-school students.
• Development of an ordinal scaling of polydrug involvement based on identified user types.
• Stepwise multiple regression analysis to identify significant predictors of polydrug involvement scores.

Main Results:

• Four distinct types of polydrug users were identified, representing an ordinal continuum of drug involvement.
• Personal motivations, including the search for pleasant sensations and expanded creativity, were significant predictors.
• Belief in cessation if drugs were proven harmful also predicted involvement.
• Sociocultural factors were less powerful predictors compared to personal motivations.

Conclusions:

• Adolescent polydrug use can be typologized, suggesting different patterns and levels of involvement.
• Psychological factors, particularly the pursuit of positive experiences and cognitive enhancement, are key drivers of polydrug use.
• Intervention strategies should consider addressing these underlying personal motivations to effectively reduce adolescent polydrug involvement.
