“…Over the past decade, the proportion of older adults who use cannabis or alcohol has risen sharply ( Grant et al, 2017 ; Han, Moore, Sherman, Keyes, & Palamar, 2017 ; Han, Sherman, et al, 2017 ). Past-year cannabis use among adults aged ≥65 in the United States (US) rose from 0.4% in 2006 to 4.2% in 2018 ( Han, Moore, et al, 2017 ; Han & Palamar, 2020 ), and past-month binge drinking increased from 8.1% in 2005/2006 to 11.1% in 2019 ( Al-Rousan, Moore, Han, & Palamar, 2022 ; Han, Moore, et al, 2017 ). With the increase in both cannabis and alcohol use, associations have been established between cannabis use and binge drinking among older adults ( Al-Rousan, Moore, Han, Ko, & Palamar, 2022 ; Han, Moore, et al, 2017 ; Han, Moore, Ferris, & Palamar, 2019 ; Han, Sherman, et al, 2017 ).…”
