Ethanol intake increases during continuous administration of amphetamine and nicotine, but not several other drugs.
Groups of rats, acclimated to drinking both water and 10% v/v ethanol were implanted with a variety of slow-release devices containing d-amphetamine (d-amp), nicotine, caffeine, phencyclidine (PCP), secobarbital, LSD, mescaline or haloperidol. Ethanol intake was elevated only during treatment with d-amp or nicotine; none of the other drugs affected ethanol consumption even though the amounts of all drugs released were pharmacologically sufficient to affect behavior. Nicotine treated rats were not simply seeking calories provided by the EtOH solution, since nicotine treatment did not enhance intake of a distinctively flavored solution isocaloric to 10% ethanol. These results support a self-medication model of ethanol intake.
