Lower socio-economic status (SES) smokers tend to smoke more heavily, be more highly dependent on nicotine, and be less successful and confident in quitting.1-4 For this reason they may benefit from extended and/or more intensive cessation interventions. It is therefore important that governments ensure such treatments and services are affordable, accessible, and attractive to disadvantaged smokers. Despite their lower success rates, low-SES smokers report being just as likely to prioritise and attempt quitting as high-SES smokers.4
Telephone-based cessation information and counselling services, such as the Quitline, offer enormous potential for the delivery of low cost and high reach cessation interventions (See Chapter 7, Section 7.14 ). Disadvantaged groups may face additional barriers to using the Quitline, such as lacking access to a phone,5 and the cost of making the call from a mobile.6 Nonetheless, recent Victorian data show that low SES smokers were just as likely to call the Quitline in 2015 as high SES smokers, and were more likely to have visited the Quit website to obtain information about cessation (see Figure 9.9.1).4

Further, although they may have lower success rates than higher SES smokers,7 quit rates among priority population callers to the Quitline suggest that the service is effective when used by high risk and underserved populations.8 In Australia, increased spending on (and therefore greater levels of public exposure to) antismoking campaigns appears to be as effective in prompting additional calls to the Quitline in lower, compared to higher, SES groups.9
Since February 2011, the Australian government has provided heavy subsidises of one 12-week course of nicotine patches per year with a prescription via the Pharmaceutical Benefits Scheme (PBS), with even greater subsidies for concession card holders.10 Indigenous Australians can access additional courses of NRT at low or no cost under the Closing the Gap scheme and/or via community organisations.11, 12 Mental health facilities and prisons—which are overrepresented by disadvantaged groups—also generally provide access to NRT.12 Bupropion (Zyban SR® and Prexaton ®) and varenicline (Champix®) have been available on Australia’s PBS since 2001 and 2008, respectively.
Figure 9.9.2 shows the number of concessional and non-concessional prescriptions filled for cessation medications under the PBS since 2001. There was a substantial increase in uptake of NRT, bupropion, and varenicline, both among concessional and general patients, when each of these medications was added to the PBS. Since 2014, more prescriptions have been provided to smokers with concession cards, with a substantially higher proportion of NRT prescription recipients being concessional. In 2017, 79% of all NRT prescriptions were for concession patients.

Other Australian data similarly shows high uptake of cessation medications among low-income groups. An analysis of data from the Australian National Drug Strategy Household Survey between 2001 and 2010 concluded that low-SES smokers use cessation support and services equally compared with high-SES smokers. Low-SES smokers were generally more likely to seek help from a doctor and to use prescription medication than high-SES smokers, which indicates their willingness to receive assistance with their quit attempts.13 Figure 9.9.3 presents data from wave eight (2010) of the International Tobacco Control Four-country Survey showing prescription medication use on the most recent quit attempt by annual household income. Those in the lowest income households were more likely than households of higher income to report using prescription stop-smoking medication.

More recent Victorian data similarly shows that low- and mid-SES smokers who had tried to quit in the past year tended to be more likely than high-SES smokers to use cessation aids or support (see Figure 9.9.4). In particular, more low-SES smokers had used cessation medications and internet sites than mid- and high-SES smokers.

Despite these encouraging findings, disadvantaged groups may still face barriers to accessing and using cessation medications. Even with subsidisation, the cost of pharmacotherapies may hinder their use among those on low incomes.14, 15 The cost and time associated with visiting a doctor to obtain a prescription may outweigh the benefits of subsidies for such smokers.14 Recent Victorian research found that low-SES smokers were equally likely to be aware that NRT is available on the PBS;4 however some groups, such as Indigenous Australians16 and clients of social and community services,15 may lack such awareness. Australian smokers may underrate the potential usefulness of cessation interventions and pharmacotherapies, and this is particularly true for smokers in low-income groups.17, 18 A qualitative study with Indigenous Australians found that some participants were skeptical and distrustful of pharmaceutical support for quitting, perceiving it as addictive and its use as evidence of poor willpower.19 Limited availability of cessation products in remote communities can also hinder use.20 US researchers found that very low-income smokers may also believe that cessation medications are dangerous.21
Targeted national smoking cessation services appear to reduce inequalities in smoking prevalence by achieving higher reach among disadvantaged smokers, compensating for their overall lower quit rates.22 An Australian study found that offering subsidised NRT increased engagement with the Quitline among low-income smokers, which promoted successful quitting.23
Adherence to pharmacotherapy (i.e., taking it as directed) increases the chances of cessation, however low-SES smokers are more likely to discontinue treatment early.24 A small Australian study found that among Indigenous Australians who had used cessation aids, none had completed the full course of treatment.19 A study of smokers using NRT in the general US community (i.e. NRT purchased over the counter rather than prescribed by their doctor) found that those with very low incomes and those of minority status were much more likely to discontinue NRT use if they had slipped up, if they suffered side effects, or if they felt that it was not helping with quitting.25
Similarly a study of smokers using cessation services in the UK (which included group program and one-to-one behavioural support, as well as the offer of pharmacotherapy) reported that at 52-week follow up, 14% of smokers of higher-SES had remained quit, compared to about 5% of smokers in the lowest socio-economic group. The researchers concluded treatment compliance was one of the factors relating to disparity in quitting success.26 Tobacco control interventions that increase support for quit attempts, enhance motivation and self-efficacy, and reduce other life stress may help to increase treatment compliance among low-SES groups.24
Data from the seventh wave of the International Tobacco Control Four-country Survey (between October 2008 and March 2009) showed that smokers of lower educational attainment were more likely than any other group to report being advised to quit smoking by their doctor. There was a slight increase from 2006 among smokers who had completed schooling, obtained a trade qualification or completed some university reporting being advised to quit (up from 51%, 52% and 48% respectively).

Nonetheless, there are some settings where disadvantaged smokers may be less likely to receive advice and support to quit. Smoking has traditionally been supported and encouraged in mental health and drug and alcohol settings (see Section 7.12 ). The normalisation of smoking among Indigenous communities, along with the high prevalence among healthcare workers, can similarly hinder the provision of cessation support (see Chapter 8 ). Encouraging and integrating tobacco cessation with such populations and settings may form an important part of reducing the disparities in smoking and health.
