HealthDay News — From 2002 to 2015 there was an increase in reported cannabis use among parents with children in the home, according to a study published online May 14 in Pediatrics.

Renee D. Goodwin, PhD, MPH, from the City University of New York in New York City, and colleagues examined changes in the prevalence of any cannabis use and daily cannabis use among parents (identified as cigarette smokers or nonsmokers) with children at home. Data were obtained from the National Survey on Drug Use and Health from 2002 to 2015. The researchers did not have information on the method of cannabis use (ie, smoking versus edible forms).

The researchers found that from 2002 to 2015 there was an increase in past-month cannabis use among parents with children in the home, from 4.9 to 6.8%, whereas cigarette smoking decreased from 27.6 to 20.2%. Over the same time period there was an increase in cannabis use, from 11.0 to 17.4% among cigarette-smoking parents, and from 2.4 to 4.0% among non-cigarette-smoking parents. Compared with nonsmokers, cigarette smokers more often had cannabis use (17.4 vs 4.0 percent; adjusted odds ratio, 3.88) and daily cannabis use (4.6 vs 0.8 percent; adjusted odds ratio, 3.70). From 2002 to 2015 there was a decrease in the overall percentage of parents who used either cigarettes and/or cannabis (from 29.7 to 23.5%).

“Efforts to decrease secondhand smoke exposure via cigarette smoking cessation may be complicated by increases in cannabis use,” the authors write. “Educating parents about secondhand cannabis smoke exposure should be integrated into public education programs on secondhand tobacco smoke exposure.”
