Effects of adolescent onset voluntary drinking followed by ethanol vapor exposure on subsequent ethanol consumption during protracted withdrawal in adult Wistar rats

► Ethanol exposure during early adolescence increases risk of dependence in adults. ► Adult ethanol-intake was measured after adolescent ethanol drinking and ethanol vapor. ► Adolescent ethanol vapor exposure modestly increased adult ethanol intake. ► Adolescent vapor exposure may be less potent than adult vapor in increasing drinking.
