A recent study suggests that people who smoke soon after getting up are more likely to develop cancer than those who do not smoke until later in the day. The study of several thousand smokers, published in a leading medical journal said that the effects were completely independent of other smoking habits.
The results found that if a person was to start smoking a cigarette inside the first thirty minutes after awaking, then risks of developing lung cancer were almost doubled.!
What cancer research in the UK suggested that people who smoked soon after getting up were probably more to inhale more (smoke) than a person who did not smoke immediately, so this was the reason for the observed results. The demographic group studied was over 4,700 smokers that had cancer and 2,800 people who smoked that did not have cancer. It showed that the people who started smoking within the first thirty minutes of awakening were 80% more likely to get lung cancer than those people who waited for at least sixty minutes.
The research also determined that this effect was seen to be true even after the figures were adjusted to take into account other things such as how many cigarettes were smoked in the day. In another research study of two thousand smokers, where over one thousand people had cancer, discovered that the smokers who lit up within 30 mins of getting up, were 60% more susceptible to getting cancer that that did not smoke for 60 mins or more.
It can be seen that there is some kind of correlation between these studies, but as to exactly what the real truth is, it is still difficult to determine. This is the considered view that current addiction levels could be responsible.
The lead researcher has said that because the smokers who light up within the first 30 mins tend to have more addiction and additional nicotine levels in their body, then this could be a factor. Also, a UK cancer research professor said that people who smoke soon after awakening also tend to inhale more intensely.
One of the possible explanations for these findings is that because a smoker starts smoking sooner, then the more they are added to smoking, and they are likely to smoke more intensely and draw more cancer causing chemicals into their lungs.
A more detailed study should look into actual nicotine blood levels and take these into account also.
