Abstract
Animal models are used to study many human diseases, one of which is tobacco addiction. Most preclinical models use nicotine alone, although there are >7000 constituents present in tobacco smoke. The clinical literature suggests that cigarettes have a strong addictive potential, which is not paralleled in preclinical studies using nicotine alone. In order to address the gap between clinical and preclinical literature on tobacco dependence, cigarette smoke extracts containing tobacco constituents have been developed. This unit describes a procedure for producing an aqueous cigarette smoke extract (CSE) which animals readily self-administer. In addition, we describe how to make the apparatus for producing CSE and how to analyze the solution for nicotine content. © 2016 by John Wiley & Sons, Inc.
