Figure 1

A. Mean (± sem) numbers of deliveries of alcohol in rats with access to alcohol alone (n=11) or alcohol + nicotine (n=8) administered vehicle (0) or varenicline (1 and 2 mg/kg) 15 min prior to 2 h SA sessions, in counterbalanced order with 2–3 days of SA between each dose. B. Mean (± sem) number of deliveries of nicotine in rats with access to nicotine alone (n=8) or nicotine + alcohol (n=8). Open circles: alcohol alone, closed circles: alcohol + nicotine, open triangles: nicotine alone, closed triangles: nicotine + alcohol.
