Replication Data for: Associations between smoking behavior and cognitive functioning in a clinical sample with alcohol use disorder

In clinical addiction care, tobacco is the most commonly used substance among patients. While the harmful effects of smoking on physical health are widely recognized, its additional impact on cognitive deficits associated with alcohol consumption remains under-researched. This study aimed to investigate cognitive differences between smoking and nonsmoking individuals with alcohol use disorder (AUD). We reviewed clinical records and neurocognitive data from 100 AUD patients, assessing their smoking status and cessation. Premorbid intelligence, verbal working memory, verbal learning and long-term memory, processing speed, inhibitory control, and cognitive flexibility were assessed.
