A reduction of in-home cannabis smoke could “substantially” reduce children’s exposure to toxic and carcinogenic chemicals that are in smoke, according to a study titled “Exposure to secondhand cannabis smoke among children,” published recently in JAMA Network Open. Among the 275 participants, 29 households (10.6%) reported in-home cannabis smoking, with 75 children (27.3%) showing detectable urinary cannabinoids. In households with reported in-home smoking, odds of detectable THC equivalents in children’s urine were “significantly higher” compared to those without smoking (odds ratio [OR], 5.0; 95% CI, 2.4-10.4).
