Dual use of tobacco and cannabis is increasingly common, but it is unclear how
it impacts individuals' interest in or ability to stop smoking. If dual users
fail to engage in treatment or have worse treatment outcomes, it would suggest
that tobacco treatment programs may need to be tailored to the specific needs
of those using cannabis and tobacco. Methods: We conducted an observational
study using electronic treatment records from adults (18 years and older) who
(a) were enrolled in a regional healthcare system in Washington state, (b)
sought tobacco cessation treatment through an insurance-covered quitline from
July 2016 to December 2018 and (c) had cannabis use frequency during the period
of their quitline enrollment documented in their electronic health record (EHR)
(n = 1,390). Treatment engagement was defined by the total number of quitline
counseling calls and web-logins completed. Point prevalent self-reported
tobacco abstinence was assessed 6 months post-quitline enrollment. Results:
Thirty-two percent of participants (n = 441) reported dual use of tobacco and
any cannabis during the observation period; 9.4% (n = 130) reported daily
cannabis use. Among dual users reporting daily cannabis use, 13.9% had a
diagnosed cannabis user disorder in the EHR. Neither engagement with quitline
counseling nor long-term tobacco abstinence rates differed between those using
tobacco-only and either dual-use group (i.e., persons using any cannabis or
daily cannabis). Conclusions: Dual use of tobacco and cannabis is common among
smokers seen in primary care and those enrolling in quitline care, but it may
not undermine tobacco quitline engagement or smoking cessation. Opportunities
exist in the US to leverage quitlines to identify and intervene with dual users
of tobacco and cannabis. HIGHLIGHTS Tobacco quitline care was equally engaging
and effective among tobacco users and dual users of tobacco and cannabis Many
daily cannabis users calling tobacco quitlines likely have a cannabis use
disorder Tobacco quitlines can be leveraged to identify and intervene with dual
users of tobacco and cannabis.
