RT Journal Article SR Electronic T1 Cannabis in homes with children: use and storage practices in a legalised state JF Injury Prevention JO Inj Prev FD BMJ Publishing Group Ltd SP 89 OP 92 DO 10.1136/injuryprev-2019-043318 VO 26 IS 1 A1 Brooks-Russell, Ashley A1 Hall, Katelyn A1 Peterson, Anne A1 Graves, Janessa A1 Van Dyke, Mike YR 2020 UL http://injuryprevention.bmj.com/content/26/1/89.abstract AB Our objective was to examine the prevalence of cannabis in homes with children and temporal trends in storage practices among caregivers. Caregivers of children ages 1–14 in Colorado, identified through a representative population-based telephone survey, participated in a repeated telephone survey from 2014 to 2017. Representing 79 805 households in Colorado with children, 8.6% (95% CI 7.3 to 10.0) of caregivers reported cannabis in the home. From 2014 to 2017, the prevalence of reporting cannabis in the home increased significantly from 6.9% to 11.2% (p=0.02). Among caregivers who reported cannabis in the home, 91.4% reported storage locations inaccessible to children, such as ‘out of reach’. Fewer, 67.0%, caregivers reported storage in a locked container, such as a cabinet, drawer or safe. In a state with recreational cannabis, an increasing number of children live in homes where cannabis is present. Public health practitioners should promote messages to caregivers about safe cannabis storage practices.
