Yale University School of Medicine reveals the relationship between smoking and drinking
A high degree of co-existence between alcohol dependence and smoking. Although abstinence period of continued smoking may reduce the risk of recurrence, but the majority of alcohol dependence-related morbidity due to smoking, and many people in the alcohol treatment also showed a desire to quit smoking. Recently, published in the United States, “National Academy of Sciences” on a study suggests that smoking may block the brain during alcohol γ- aminobutyric acid A (GABAA) receptor recovery.
Although scientists unclear smoking on neural adaptations and behavior of alcohol-dependent smokers changes occur during abstinence role, but to better understand the role of tobacco and alcohol may contribute to the design of therapeutic strategies related.
Kelly School of Medicine, Department of Psychiatry, Yale University, USA P. Cosgrove and colleagues studied 52 subjects and 13 male rhesus monkeys were studied in order to investigate smoking and nicotine abstinence period of GABAA receptor availability change effect. Brain imaging showed that both smokers or non-smokers, the GABAA receptor levels in the first week of abstinence will increase.
However, the presence of alcohol dependence and alcohol nonsmokers GABAA receptors in the period after the control level in the back, while alcohol-dependent smokers multiple brain regions appear GABAA receptor levels continue to rise. These elevated and associated craving alcohol and cigarettes.
