Cigarette Smoking in Smokers With and Without a Diagnosis of Schizophrenia

University of Maryland, Baltimore·interventional·Posted Jun 27, 2019·Updated Sep 26, 2024

In Brief

A clinical study evaluating Sampling Research Cigarettes for Tobacco Dependence and Schizophrenia. Completed, enrolled 31 participants across 1 site.

Detailed Summary

Higher rates and severity of tobacco dependence in people with schizophrenia, as compared with the general population, contribute to the lower life expectancy seen in this population. Dependent tobacco smoking is controlled by how different aspects of cigarette smoking are perceived. There is evidence suggesting that people with schizophrenia differ in how they perceive cigarette smoking, which, if confirmed, would have implications for tailoring treatment interventions for smoking cessation in schizophrenia.

Interventions

Sampling Research Cigarettescombination

Participants sample two research cigarettes, which differ in typical tobacco smoke constituents such as tar, nicotine, carbon monoxide, etc. In the Cigarette Discrimination Session, participants sample both types of cigarettes repeatedly, guess their identity (A or B) with regard to reference cigarettes, and rate their subjective effects. In the Ad Libitum Smoking Session, participants can smoke one of these cigarette types as much or as little as they like for eight hours.
