According to a study published in “Cancer” and conducted by researchers from the College of Medicine at Penn State Hershey of 7611 people, the first cigarette of the day, those who smoke within half an hour of waking up, the first cigarette of the morning is one that does more harm is the most dangerous and does increase the risk of lung cancer, head and neck.
The researchers do not rule out the risk even more if you raise the cigarette is smoked and sucked in the first fifteen minutes of waking. The first cigarette of the morning is one that does more harm, to increase the cancer risk is the amount of nicotine in the blood, which vary considerably depending on when you turn the first “blonde” of the day: “During the first 5 minutes of the day, the nicotine in the blood increased up to 437 nanograms per milliliter; between 6 and 30 minutes and after an hour up to 352 up to 215″. It is not to be taken into account as a risk factor, only the amount of cigarettes smoked per day but also the time of day when you start smoking.
“The first cigarette of the morning is one that does more harm, smokers have higher levels in the body of nicotine and possibly other tobacco toxins – said Oman, who led the research – and may be more dependent than those who resist smoke for half an hour or more. Greater nicotine dependence may be determined by a combination of genetic and personal factors”.
