Rehab News: Nicotine-alcohol interaction could affect alcohol treatment
The interaction between nicotine and alcohol can impact upon a person's ability to learn and may therefore have implications for alcohol treatment, researchers have said.
A new study by experts at Temple University looked at people's ability to learn and process contextual information, a type of learning that involves a part of the brain called the hippocampus.
Thomas Gould, an associate professor of psychology at Temple University, said that the goal of the research was to understand the interactive effects of nicotine and alcohol.
He revealed: "Our study showed that initially nicotine in a dose-dependent manner reverses alcohol-induced deficits in learning, but tolerance develops for this effect of nicotine with continued administration.
"We also found that a low dose of alcohol reverses nicotine withdrawal-associated deficits in learning. Furthermore, we found that chronic nicotine produces cross-tolerance to the effects of a low dose of alcohol on learning."
Professor Gould explained that if people are addicted to both drinking and smoking and attempt to give up cigarettes, they will experience a learning deficit.
"Maybe a drink will actually help them out initially, but then they consume more and they develop even worse learning deficits, so now they begin smoking again and they end up relapsing," he said.
The researchers hope that by boosting their understanding of the interaction between nicotine and alcohol "we will hopefully be in a better position to develop treatments for drug addiction".
The study is due to be published in the journal Psychopharmacology.
