Coffee and Cigarettes

 From Neuroscience News:

For some smokers, the first cigarette of the day is just not as satisfying without a cup of coffee. That could be more than just a morning habit: Chemical compounds in roasted coffee beans may help lighten the effects of morning nicotine cravings, University of Florida researchers have found.

In a cell-based study, the researchers identified two compounds in coffee that directly affect certain high-sensitivity nicotine receptors in the brain. In smokers, these brain receptors can be hypersensitive after a night of nicotine withdrawal.

The recently published findings have yet to be tested in humans but are an important step toward better understanding how coffee and cigarettes affect nicotine receptors in the brain, said Roger L. Papke, Ph.D., a pharmacology professor in the UF College of Medicine. Caffeine is coffee’s feel-good ingredient for most people but smokers may get another kind of boost.

“Many people like caffeine in the morning but there are other molecules in coffee that may explain why cigarette smokers want their coffee,” Papke said. (Read more.)
