BOSTON, May 4 (UPI) — Children who begin smoking do not recognize that being irritable is an early sign of addiction, University of Massachusetts researchers said.
“Previous studies have already shown that there is a strong correlation between symptoms of nicotine dependence and nicotine addiction,” Dr. Chyke Doubeni said in a statement. “This study shows that adolescents who start smoking, don’t appear to recognize the early signs of dependence.”
Doubeni said other signs of early dependence on nicotine include a desire to smoke or craving for a cigarette.
The study is based on data from surveys of adolescent smokers every three to four months from 2002-2006.
The study, published in the journal Pediatrics, found non-daily use of tobacco can trigger any early signs of dependence, which in turn, increased smoking.
The study also found during the 4-year study, of the 370 subjects who had inhaled cigarette smoke, 62 percent smoked at least once per month, 52 percent experienced dependence symptoms and 40 percent became daily smokers.
