Do you think your “light” smoking habit is not that dangerous? Casual smokers can also become nicotine addicted, according to a new study.
According to researchers, people who smoke less than 1 to 4 cigarettes a day meet the criteria for nicotine addiction and should consider treatment.
“In the past, some thought that only patients who smoked about 10 or more cigarettes a day were addicted, but I still hear it from time to time,” said Pennsylvania’s Public Health Sciences and Psychiatry. Said research co-author Jonathan Falls, a professor of behavioral health. The State Cancer Institute in Hershey, Pennsylvania.
“But this study shows that many light smokers, even those who don’t smoke daily, can be addicted to tobacco,” said a news release from Pennsylvania State University. “It also suggests that we need to be more accurate when we ask about how often we smoke.”
Doctors use the 11 criteria listed in the 5th edition of the Diagnostic and Statistical Manual (DSM-5) to determine the number of cigarettes they smoke, rather than determining if someone is nicotine addicted. I often ask the patient.
Light smoking is seen as less harmful than heavy smoking, but researchers say it is still dangerous.
For this study, researchers examined data from more than 6,700 smokers evaluated to see if they met the DSM-5 criteria for tobacco use disorders.
They found that 85% of daily smokers were nicotine addicted.
“Surprisingly, almost two-thirds of people who smoke only one to four cigarettes a day are addicted, and about a quarter of smokers who smoke less than a week are addicted.” Foulds said.
Researchers have also found that nicotine addiction increases with frequency. Studies have shown that 35% of people who smoke 1 to 4 cigarettes a day and 74% of people who smoke 21 or more cigarettes daily have moderate or severe addiction.
Jason Oliver, co-author of the study and assistant professor of psychiatry and behavioral science at Duke University in Durham, North Carolina, said doctors should ask patients about smoking behavior. Even those who don’t smoke every day may need treatment to quit smoking, the researchers said.
