GSK study says about half of smokers drink coffee while smoking

PITTSBURGH A new survey from GlaxoSmithKline shows half of all smokers regularly drink coffee and smoke at the same time, the smoking cessation supplier reported Monday.

A recent survey conducted by the marketers of Commit Cappuccino, a new smokcing-cessation lozenge flavor, shows that while smokers drink almost twice as much coffee as nonsmokers, an overwhelming 86 percent surveyed are unaware that they may need to cut back their caffeine intake when trying to quit.

Studies show that smoking causes smokers to metabolize caffeine faster. As a result, smokers need to ingest more caffeine to get the same effects of nonsmokers. So when a smoker tries to quit, they may end up with more caffeine in their system, and may need to reduce their caffeine intake when trying to quit. In fact, the survey shows that fewer than one in 10 smokers (9 percent) know how smoking affects the way their body processes caffeine. Additionally, about one-third of smokers (about 32 percent) do not know that too much caffeine in the blood can be harmful.

“It is important smokers understand that they don’t need to give up coffee when trying to quit, but by drinking less coffee, they may help their body adjust to life without cigarettes, and avoid caffeine side effects,” said Saul Shiffman, researcher and professor in the departments of psychology and pharmaceutical science at the University of Pittsburgh and GlaxoSmithKline Consumer Healthcare spokesman.

Among the adults surveyed, smokers drink an average of 2.8 cups of coffee per day, while nonsmokers drink 1.5 cups. And almost half (about 43 percent) of smokers report that drinking coffee makes them want to have a cigarette.
