SMOKERS who light up first thing in the morning have a much greater chance of suffering lung cancer than those who wait till later in the day.
Scientists have found increased levels of harmful nicotine in the lungs of smokers who have their first cigarette minutes after waking.
The researchers said the amount of cotinine - a byproduct of nicotine - among people who smoke first thing in the morning was higher regardless of the number of cigarettes smoked.
