A recent study published in online Cancer: Journal of the American Cancer Association concluded that smokers who smoke their first cigarette shortly after they wake up in the morning may have a higher risk of lung and head and neck cancers than those who smoke later.
The study included 4,775 lung cancer cases and 2,835 controls and all were regular smokers. Those smoking 31 to 60 minutes after waking were 1.31 times more likely to develop lung cancer than those who smoked more than 60 minutes after waking. In addition, those who smoked within 30 minutes after waking were 1.79 times more likely to develop lung cancer.
The researchers also analyzed 1,055 head and neck cancer cases and 795 controls who had a history of smoking. Individuals who smoked 31 to 60 minutes after waking 1.42 times more likely to develop head and neck cancer than those who smoked more than 60 minutes after waking. In addition, those who smoked within 30 minutes were 1.59 times more likely to develop head and neck cancer. Thus, the researchers concluded that the need to smoke immediately after waking in the morning may increase a smokers chances of getting cancer.
