Abstract

Oral nicotine pouches may have potential for smoking cessation, but scientific evidence on the effects of pouches and their constituents on smoking behaviour is limited.

Design: This study was a 4-week, open-label, randomised pilot trial of nicotine pouches in 3 mg (low) or 6 mg (high) nicotine strength.

Subjects: US outpatient research clinic with non-treatment seeking adults who smoke cigarettes (N=30).

Interventions: Participants selected two flavours and were instructed to switch to using nicotine pouches in place of cigarettes.

Main outcome measures: We compared groups on cigarettes smoked per day, pouch use and urinary levels of a tobacco-specific carcinogen (NNAL) over 4 weeks, biochemically verified 7-day point prevalence smoking abstinence at week 4, and willingness to continue pouch use.

Results: Nearly all participants completed the trial (29/30). Participants in both groups significantly reduced their cigarettes smoked per day (log-transformed) over time (F3, 74.4=3.8, p=0.01). The 6 mg group reported numerically greater, but non-significant, reductions in smoking than the 3 mg group (least-square mean difference (LSMD) at week 1=0.008; 95% CI -0.42-0.44; LSMD at week 4=0.38; 95%CI -0.06-0.81). The 6 mg group also reported numerically higher, but non-significant, likelihood of complete smoking abstinence (13% vs 0%) and willingness to continue pouch use (67% vs 40%). There were no differences by group or time for NNAL.

Conclusions: Results provide preliminary support for nicotine pouches for cigarette substitution. Compared with lower nicotine strength pouches, higher nicotine strength pouches may have a greater impact on smoking behaviour and adults who smoke may be more willing to use them.

口服尼古丁袋对吸烟行为和烟草危害暴露的影响:一项成人随机试点试验。
口服尼古丁袋可能具有戒烟的潜力,但关于尼古丁袋及其成分对吸烟行为的影响的科学证据有限。设计:本研究是一项为期4周的、开放标签的、随机的、尼古丁含量为3毫克(低)或6毫克(高)的尼古丁袋装试验。对象:美国门诊研究诊所非治疗寻求吸烟成人(N=30)。干预措施:参与者选择了两种口味,并被指示改用尼古丁袋代替香烟。主要结局指标:我们比较了各组在4周内的每日吸烟量、烟袋使用和尿中烟草特异性致癌物(NNAL)水平,第4周生化验证的7天点状戒烟率,以及继续使用烟袋的意愿。结果:几乎所有参与者都完成了试验(29/30)。随着时间的推移,两组参与者每天吸烟的数量都显著减少(对数转换)(F3, 74.4=3.8, p=0.01)。6毫克组报告的吸烟率比3毫克组减少的数值更大,但不显著(第1周的最小二乘平均差(LSMD) =0.008;95% ci -0.42-0.44;第4周LSMD =0.38;95% ci -0.06-0.81)。6毫克组也报告了更高的数字,但不显著,完全戒烟的可能性(13%对0%)和继续使用烟袋的意愿(67%对40%)。NNAL组间和时间间无差异。结论:研究结果为尼古丁袋替代卷烟提供了初步支持。与低尼古丁强度的烟袋相比,高尼古丁强度的烟袋对吸烟行为的影响可能更大,吸烟的成年人可能更愿意使用它们。试验注册号:NCT04250727。
