Utilisation of smoking cessation aids among South African adult smokers: findings from a national survey of 18 208 South African adults

OBJECTIVE: To examine the use of different cessation aids among current South African smokers who have ever tried to quit smoking. DESIGN: Cross-sectional design. SETTING: South Africa has progressively passed several policies over the past few decades to encourage smoking cessation. Data on cessation behaviours are needed to inform policymaking. We investigated utilisation of evidence-based cessation aids and e-cigarettes among current combustible smokers. Current tobacco use, past quit attempts and use of evidence-based cessation aids (counselling, nicotine replacement therapy or prescription medication) were self-reported. Data were weighted and analysed using descriptive and multivariable approaches (p<0.05). PARTICIPANTS: Online participants were recruited from the national consumer database for News24—South Africa’s largest digital publisher. Of the 18 208 participants aged 18 years or older, there were 5657 current smokers of any combustible tobacco product (cigarettes, cigars, pipes or roll-your-own cigarettes), including 4309 who had ever attempted to quit during their lifetime. RESULTS: Current combustible tobacco smoking prevalence was 22.4% (95% CI: 21.2% to 23.5%), and 98.7% of all current smokers of any combustible tobacco were current cigarette smokers. Awareness of cessation aids was as follows among current combustible tobacco smokers: smoking cessation counselling programmes, 50.8% (95% CI: 48.1% to 53.6%); nicotine replacement therapy, 92.1% (95% CI: 90.5% to 93.6%); prescription cessation medication, 68.2% (95% CI: 65.2% to 70.6%). Awareness of cessation aids was lowest among Black Africans, men, and persons with little or no income. Of all current combustible tobacco smokers, 74.6% (95% CI: 72.2% to 76.7%) had ever attempted to quit and 42.8% (95% CI: 40.0% to 45.4%) of these quit attempters had ever used any cessation aid. Among current combustible smokers who attempted to quit in the past, ever e-cigarette users were more likely than never e-cigarette users to have ever used any cessation aid (50.6% vs 35.9%, p<0.05). Of current combustible smokers intending to quit, 66.7% (95% CI: 64.2% to 68.9%) indicated interest in using a cessation aid for future quitting. By specific aids, 24.7% (95% CI: 21.3% to 28.1%) of those planning to use any cessation aid were interested in getting help from a pharmacist, 44.6% (95% CI: 40.9% to 48.4%) from a doctor, 49.8% (95% CI: 46.0% to 53.6%) from someone who had successfully quit, 30.0% (95% CI: 26.7% to 33.4%) from a family member and 26.5% (95% CI: 23.0% to 30.0%) from web resources. CONCLUSION: Only two in five past quit attempters had ever used counselling/pharmacotherapy. Any putative benefits of e-cigarettes on cessation may be partly attributable to pharmacotherapy/counselling given concurrent use patterns among past quit attempters using e-cigarettes. Comprehensive tobacco control and prevention strategies can help reduce aggregate tobacco consumption.
