Among 233 adults diagnosed with ketamine use disorder and referred for court-ordered addiction treatment, those at risk for problematic smartphone use spent significantly more time on their phones daily, had higher scores on an adult ADHD self-report scale, and were more than twice as likely to use their smartphones for online gaming. The findings suggest that excessive smartphone use in this population is closely tied to gaming, and that ADHD symptoms may increase the risk of problematic use.
