项目摘要
This application is being submitted in response to the Notice of Special Interest (NOSI) identified as NOT-
CA-22-070, Administrative Supplements for Examining Patterns of Tobacco and Cannabis Use. The prevalence of
cannabis use is elevated among adults who smoke, and particularly among those with low socioeconomic status.
However, the impact of cannabis use on smoking cessation remains unclear. The proposed administrative
supplement will leverage an ongoing smoking cessation intervention trial for low-income adult smokers
(R01CA251451) to collect new data to characterize baseline and daily cannabis and tobacco use and co-use patterns,
compare cannabis users and non-users on respiratory symptoms and mental/physical health, and evaluate the impact
of cannabis use on daily smoking and point prevalence smoking abstinence at post-quit follow-up. Data from 135
adults enrolled in the ongoing parent trial will be included in the proposed analyses, to be completed within the 1-year
supplement time frame. All participants will provide information about their tobacco and cannabis use at baseline, prior
to initiating smoking cessation treatment, and they will complete smartphone-based assessments of their expired
carbon monoxide (CO), self-reported tobacco and cannabis use, and other relevant factors over a 7-week period (1-
week pre-quit day through 4 weeks post-quit, and during post-quit weeks 8 and 12). Follow-up assessments of CO-
verified 7-day point prevalence smoking abstinence will focus on follow-ups at 4, 8, and 12 weeks post-quit to fit within
the 1-year supplement time frame. The supplement will address the following specific aims: 1) Characterize cannabis
use characteristics among low-income adults participating in tobacco cessation treatment, including a) baseline and
daily prevalence, frequency, intensity, and modalities of cannabis use (e.g., combusted vs. non-combusted) as well as
reasons for use, b) baseline cannabis dependence severity and harm perceptions, c) daily prevalence of tobacco and
cannabis co-use assessed via smartphone-based daily diaries, and d) interest at baseline and follow-up in reducing or
abstaining from cannabis use; 2) At baseline, compare past 30-day cannabis users with non-users on
sociodemographic characteristics, tobacco use history, physical and mental health, alcohol use, respiratory
symptoms, exposure to cannabis secondhand smoke, expired CO levels, and cigarette dependence; 3) Evaluate the
within-day and distal relationships between cannabis use and smoking cessation, including: a) the relation between
baseline cannabis use (past 30-day use vs. non-use) and smoking cessation outcomes at follow-up (4, 8, and 12
weeks post-quit), b) the within-day relations of cannabis use with cigarette craving, withdrawal symptom severity, and
smoking during the weeks following a scheduled quit attempt via smartphone-based assessments, and c) the relation
of cannabis use frequency (i.e., near daily use, days of use) during the first 4 weeks following a scheduled smoking
quit attempt with CO-verified point prevalence smoking abstinence at follow-ups. Findings will yield important
information about the impact of cannabis use during smoking cessation treatment, and identify factors that can be
targeted in cessation interventions.
本申请是为了回应特别利益通知(NOSI)而提交的,该通知被确定为不-
CA-22-070,检查烟草和大麻使用模式的行政补充。之时尚
在吸烟的成年人中,特别是在社会经济地位较低的人中,大麻使用率较高。
然而,大麻使用对戒烟的影响仍不清楚。拟议行政
补充将利用正在进行的低收入成年吸烟者戒烟干预试验
(R 01 CA 251451)收集新的数据,以描述基线和每日大麻和烟草使用及共同使用模式的特征,
比较大麻使用者和非使用者的呼吸道症状和精神/身体健康,并评估其影响
大麻使用对每日吸烟和戒烟后随访时戒烟率的影响。数据135
入组正在进行的母试验的成人将被纳入拟定的分析中,并在1年内完成
补充时间框架。所有参与者将提供有关其基线时烟草和大麻使用的信息,
开始戒烟治疗,他们将完成基于智能手机的评估,
一氧化碳(CO),自我报告的烟草和大麻使用,以及7周内的其他相关因素(1-
戒烟前一周至戒烟后4周,以及戒烟后第8周和第12周)。CO的后续评估-
经验证的7天时点戒烟率将侧重于戒烟后4、8和12周的随访,以符合
1年补充时间框架。该补编将针对以下具体目标:
参与戒烟治疗的低收入成年人的使用特征,包括a)基线和
大麻使用的每日流行率、频率、强度和方式(例如,燃烧与非燃烧)以及
使用原因,B)基线大麻依赖严重程度和危害认知,c)每日烟草流行率,
通过基于智能手机的每日日记评估大麻共同使用,以及d)基线和随访时对减少或
2)在基线时,将过去30天的大麻使用者与非使用者进行比较,
社会人口学特征、烟草使用史、身心健康、饮酒、呼吸道疾病
症状,暴露于大麻二手烟,过期的CO水平和香烟依赖; 3)评估
大麻使用和戒烟之间的日内和远端关系,包括:a)
基线大麻使用(过去30天使用与不使用)和随访时的戒烟结果(4、8和12
B)大麻使用与香烟渴望、戒断症状严重程度的日内关系,以及
通过基于智能手机的评估,在计划戒烟尝试后的几周内吸烟,以及c)
大麻使用频率(即,在计划吸烟后的前4周内,接近每日使用,使用天数)
随访时通过CO验证的戒烟率尝试戒烟。调查结果将产生重要的
关于戒烟治疗期间大麻使用的影响的信息,并确定可能影响戒烟治疗的因素。
针对戒烟干预措施。
