High doses of alcohol solution will be self-administered intragastrically after animals are made dependent via passive intragastric infusion, and rats will self-infuse 4–7 g/kg per day of ethanol (Fidler et al. 2006). Here, blood alcohol levels average 0.12 g%, measured 30 min after the start of a bout in which rats infuse 1.5 g/kg per 30 min.
