| Summary: | Introduction
Approximately 60 million individuals worldwide used opioids in 2021,
constituting 1.2% of the global adult population. This study aimed to evaluate
the effectiveness of integrated treatment strategies for opioid use disorder and
nicotine use disorder by assessing the impact of smoking cessation within a
methadone treatment framework.
Methods
In a retrospective cohort study, 53 methadone maintenance patients were
divided into 16 treatment-seeking smokers (TSS) and 37 treatment-rejecting
smokers (TRS) based on their participation in the Ottawa model for smoking
cessation plus 16 weeks of varenicline treatment. Both groups received standard
methadone treatment for 68 weeks. TSS were followed up for 44 weeks to assess
smoking cessation outcomes, while TRS had none due to their lack of participation
in smoking cessation treatment.
Results
The median age of the TSS group was 48 years, while that of the TRS group
was 45.5 years. Males comprised 75% of TSS and 94.6% of the TRS. TSS exhibited
an 83% decrease in positive opioid screen results compared to TRS (p=0.023).
In TSS, peak smoking cessation success was observed at week 20, with 57% of
participants maintaining carbon monoxide levels <5 ppm.
Conclusions
The significant reduction in positive opioid screens and the high
smoking cessation rate in the TSS group highlight the efficacy of combined
treatment methods. This study underscores the advantages of integrating smoking
cessation with methadone maintenance treatment, indicating that comprehensive
approaches can substantially improve treatment outcomes. |
