For some smokers, having a cigarette is an early morning ritual, but this habit may be even more harmful than smoking later in the day.
Smoking soon after waking up increases the risk of developing lung, head and neck cancers, two new studies show.
“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,” study researcher Joshua Muscat of the Penn State College of Medicine, said in a statement.
In an effort to determine why only some smokers get cancer, researchers investigated whether how soon a person has his or her first cigarette after waking up affects their risk of lung, head and neck cancers — independent of how often they smoke and for how long they’ve had the habit.
