Abstract
BACKGROUND: This study investigates the association between inhalant use and information processing (IP) in adjudicated polysubstance users. Polysubstance users who used inhalants (n= 158) were compared with polysubstance users who did not use inhalants (n= 303). Hispanic Americans comprised 72% of the participants; European Americans, African Americans and Asian Americans comprised 28% of the participants. METHOD: Standardized intelligence and achievement tests were used to assess information-processing constructs of working memory and processing speed. Psychosocial and substance abuse standardized surveys were used to assess drug use severity and psychosocial problems associated with substance use. RESULTS: Polysubstance users who used inhalants (PSI users) were younger, used more drugs more frequently and had more psychiatric admissions than non-inhalant polysubstance users (PSO users). Statistical analysis also shows that PSI users performed worse on measures of IP selected tests in comparison with the PSO users. CONCLUSION: Inhalant users begin abusing substances at a younger age and suffer from more verbal and non-verbal processing, behavioural, language and memory problems than non-inhalant users.
