Smoking in the morning 'could increase cancer chances'
People who smoke as soon as they wake up could have to claim on their medical insurance policies for cancer treatment in the future.
This is according to two studies by Columbia University and Penn State College of Medicine, published in the journal Cancer, which looked at how smoking at different times affects the likelihood of developing lung, head and neck cancers.
It was found that people who lit up under half an hour from when they awoke were 1.79 times more likely to get lung cancer than those who waited an hour or more.
The early smokers also had a 1.59 times higher chance of contracting cancer of the head and neck.
Lead author Dr Joshua Muscat suggested that these individuals may require targeted smoking cessation programmes in order to help them quit.
"These smokers have higher levels of nicotine and possibly other tobacco toxins in their body and they may be more addicted than smokers who refrain from smoking for a half hour or more," he added.
In June, a study carried out at the London School of Hygiene and Tropical Medicine found that regular motivational text messages sent to smokers while they are trying to quit could double their chances of succeeding.
