Early to Bed, Early to Rise; Early to Smoke, Early to Cancer


Smokers who pick up a cigarette first thing in the morning have a higher risk for developing lung and head and neck cancers, says CNN's Ben Tinker. According to new work published in the journal Cancer, smokers who smoke their first cigarette shortly after waking up have higher levels of nicotine and other tobacco toxins in their bodies and may be more addicted to cigarettes than other smokers who wait for a half hour or more after waking to light one up. "Subjects who smoked their first cigarette between 31 and 60 minutes after waking up were more than 30 percent more likely to develop lung cancer; the odds increased to nearly 80 percent for those who smoked in their first half-hour awake," Tinker says. "For head and neck cancers, subjects were more than 40 percent more likely if they indulged in the 31-60 minute window, and nearly 60 percent more likely for those who smoked in their first half-hour awake."
