Inhalants are frequently among the first drugs abused by adolescents; however, little is known about how chronic inhalant abuse affects cognition (e.g. executive functioning). Several studies have examined cognitive deficits among inhalant users; however, no study has thoroughly addressed the confounding issues frequently associated with inhalant users (e.g. polysubstance use). The aim of the current study was to examine possible deficits in cognitive control among young, regular inhalant users and explore the relationship between inhalant use and executive functioning. Three groups (n = 19) of young people (aged 14-24) were recruited: an inhalant-using group, a drug-using control group and a community control group. The inhalant and drug-using controls were matched on demographic, clinical and substance use measures. All three groups were matched on age, sex and education. Cognitive control was assessed using Stroop and Go/No-Go tasks. There were no significant differences in performance between the groups on any measure. However, three measures (incongruent reaction times and congruent errors for the Stroop and omission errors for the Go/No-Go) were significantly correlated with inhalant use measures, suggesting inhalant use was associated with poorer performance. The lack of significant differences between the groups is surprising; however, it raises important questions regarding cognitive deficits among chronic inhalant users. Further longitudinal studies using well-matched control participants are required to delineate the nature and timing of cognitive and neurobiological pathology among adolescent inhalant users.
