Electronic cigarettes: Ever use, current use and attitudes among alcohol and other drug clients

How do patients and staff in an opioid agonist treatment service view smoking cessation medications and e-cigarettes?

INTRODUCTION

Tobacco use and related mortality is common in people receiving opioid agonist treatment (OAT). Smoking cessation medications are available and e-cigarettes are increasingly recommended for high risk populations. This study explores experience, knowledge and attitudes around smoking cessation medications (nicotine replacement therapy [NRT], bupropion and varenicline) and e-cigarettes in patients and clinicians in two public Australian OAT clinics.

METHODS

Cross-sectional surveys of patients and clinicians and a randomly sampled retrospective medical record review. Patients were recruited through an advertisement in the clinic, and clinicians through advertisement at an educational session.

RESULTS

Ninety-one patients and 10 clinicians completed the surveys. Most patients had at least one quit attempt and 43% were currently trying to quit. There were high levels of exposure to NRT, lower levels with varenicline and very limited exposure to bupropion. Patients considered e-cigarettes most helpful, but were more likely to consider using NRT. Few patients reported smoking cessation interventions from their clinicians. Most clinicians identified high tobacco use prevalence, considered this problematic, but reported low rates of smoking cessation intervention. NRT was the preferred medication. E-cigarettes were not considered helpful. Sixty-six percent of the 140 records reviewed documented patients as smokers. Tobacco cessation medication was rarely discussed or provided.

DISCUSSION AND CONCLUSIONS

Patients report high rates of tobacco cessation planning, but low rates of intervention. Experience of varenicline and bupropion is limited. E-cigarettes were preferred over varenicline and bupropion. Improving patient's and clinician's knowledge of tobacco cessation medications could improve smoking cessation interventions and uptake of approved medications.

The prevalence of electronic cigarettes vaping globally: a systematic review and meta-analysis

BACKGROUND

The purpose of this systematic review study was to determine the national, regional, and global prevalence of electronic cigarettes (e-cigarettes) vaping.

METHOD

The articles were searched in July 2020 without a time limit in Web of Science (ISI), Scopus, PubMed, and Ovid-MEDLINE. At first, the titles and abstracts of the articles were reviewed, and if they were appropriate, they entered the second stage of screening. In the second stage, the whole articles were reviewed and articles that met the inclusion criteria were selected. In this study, search, selection of studies, qualitative evaluation, and data extraction were performed by two authors independently, and any disagreement between the two authors was reviewed and corrected by a third author.

RESULTS

In this study, the lifetime and current prevalence of e-cigarettes vaping globally were 23% and 11%, respectively. Lifetime and current prevalence of e-cigarettes vaping in women were 16% and 8%, respectively. Also, lifetime and current prevalence of e-cigarettes vaping in men were 22% and 12%, respectively. In this study, the current prevalence of e-cigarettes vaping in who had lifetime smoked conventional cigarette was 39%, and in current smokers was 43%. The lifetime prevalence of e-cigarettes vaping in the Continents of America, Europe, Asia, and Oceania were 24%, 26%, 16%, and 25%, respectively. The current prevalence of e-cigarettes vaping in the Continents of America, Europe, Asia, and Oceania were 10%, 14%, 11%, and 6%, respectively.

CONCLUSIONS

Based on the results of this study, it can be concluded that the popularity of e-cigarettes is increasing globally. Therefore, it is necessary for countries to have more control over the consumption and distribution of e-cigarettes, as well as to formulate the laws prohibiting about the e-cigarettes vaping in public places. There is also a need to design and conduct information campaigns to increase community awareness about e-cigarettes vaping.

Barriers and facilitators to using vaporised nicotine products as smoking cessation aids among people receiving treatment for substance use disorder

INTRODUCTION

Vaporised nicotine products (VNPs) may be useful smoking cessation aids for people in alcohol and other drug (AOD) treatment, a population with high tobacco-related morbidity and mortality rates. This qualitative study aimed to examine the barriers and facilitators of using VNPs as part of a clinical trial to reduce or quit smoking among people in AOD treatment.

METHODS

Thirteen people in AOD treatment who were participating in a trial of VNPs for smoking cessation (QuitENDs) completed a brief semi-structured interview examining experiences of using VNPs to reduce or quit smoking. Transcribed data was analysed using the iterative categorisation framework.

RESULTS

Many participants expressed the benefit of having a smoking cessation aid that addressed nicotine cravings and the behavioural hand-to-mouth action to help them reduce or quit smoking. Although many participants reported that VNPs were easy to use, some found maintaining the device to be challenging. Some participants described Australian regulations limiting use of VNPs as reducing their desire to use the device as a cessation aid. Many participants attempting to reduce or quit tobacco and cannabis simultaneously stated that VNPs alone were insufficient to help them reduce or quit tobacco.

CONCLUSIONS

VNPs hold significant promise as smoking cessation aids among people in AOD treatment because of their unique ability to satisfy both nicotine cravings and behavioural habits. However, multiple barriers, such as accessibility, maintenance, and the challenges of reducing other substance use simultaneously also need to be addressed for optimal engagement in clinical trials with VNPs to quit smoking.
