Persons diagnosed with ADHD in childhood have a higher likelihood of substance abuse at a later age, adding a comorbid factor to attention network deficits brought on by the diagnosis. This work uses the largest sample to date to show that drug use frequency does not bias behavioral and/or cognitive differences when performing a Go/NoGo task. The sample size and multi-site nature of the study make these results especially generalizable.
