Australia has signed the World Health Organization Framework Convention on Tobacco Control, the world’s first public health treaty, committing to a series of evidence-based national policies to reduce smoking and the harm it causes.3 Australia has implemented anti-tobacco mass media campaigns, pack warning labels, restrictions on tobacco advertising, price increases of tobacco through tax rises and smoke-free regulations, and has provided cessation services, contributing to Australia’s low national smoking prevalence.10 There is some evidence that such population health approaches also motivate Aboriginal and Torres Strait Islander people who smoke to quit. Cross-sectional and longitudinal analyses of a large national survey (Talking About The Smokes [TATS]) demonstrated the impacts of noticing anti-tobacco social marketing (eg TV advertisements and posters; with localised material having greater impact) and pack warning labels, as well as the effects of the introduction of plain packaging.24–26 Aboriginal and Torres Strait Islander people who smoked but lived in a smoke-free home not only protected children and other non-smokers from second-hand smoke, but were also more likely to quit smoking than those who did not completely ban smoking in their home.27,28 Annual tobacco tax rises were associated with an decline in tobacco sales in remote Aboriginal communities.29
Health services can contribute to these evidence-based public health tobacco control activities by promoting anti-tobacco marketing and messaging (eg posters and displays) and smoke-free rules at the health service, community organisations and events.11 Health services should have no contact with the tobacco industry and should support further restrictions on the tobacco industry, such as tobacco endgame proposals. In Aotearoa New Zealand, following Māori advocacy, these restrictions include reducing nicotine in cigarettes to very low levels, significantly reducing the number of outlets where cigarettes can be sold and prohibiting the sale of tobacco products to people born after January 2009, and so creating a smoke-free generation.30
Health practitioners play a vital role in assisting and supporting smoking cessation and reducing the harms caused by smoking. Although most people successfully quit smoking without the assistance of health practitioners, including most Aboriginal and Torres Strait Islander people, brief advice and behavioural and pharmacological therapies can increase successful cessation.3,28,31 Health practitioners can be encouraged to support smoking cessation knowing that the TATS national survey of Aboriginal and Torres Strait Islander people found that most smokers reported wanting to quit (70%), making a quit attempt in the past year (48%), regretting ever starting to smoke (78%), living in smoke-free homes (56%) and knowing about the most harmful effects of smoking and second-hand smoke.27,32–34 The most common reasons smokers and ex-smokers gave for quitting in the TATS survey were concerns for their health, cost and setting an example for children.26
Although more socially disadvantaged Aboriginal and Torres Strait Islander people have repeatedly been shown to be more likely to smoke, a longitudinal analysis of the TATS surveys showed that social disadvantage did not appear to predict quitting in the next year.35 Health practitioners can be optimistic about providing smoking cessation support to even the most disadvantaged Aboriginal and Torres Strait Islander people. Conversely, longitudinal analysis of the TATS surveys also found that people whose social circumstances improved (eg getting a job) were more likely to quit than those who did not experience this change, although it is not clear which happened first, getting a job or quitting smoking. The personal empowerment that comes from making one such successful life change can lead to other achievements.
Although a review of reviews found no evidence of greater effectiveness of culturally adapted smoking cessation compared with other services, it did find strong evidence of community preference for such culturally appropriate services.4 So, although other services can be effective, there is strong support for the importance of more culturally appropriate approaches to reducing Aboriginal and Torres Strait Islander smoking.4,17
Screening
Ask
Ask all patients whether they smoke and ensure that their current smoking status is recorded in their medical record.3,22,23,36 Regularly (at least annually) update smoking status in the medical records of anyone who smokes or has recently quit.22 A systematic approach to identifying all people who smoke should be used in every health service and has been shown to increase the support offered by health practitioners.6 Almost all (93%) Aboriginal and Torres Strait Islander people who smoke daily who had seen a health professional in the previous year reported being asked whether they smoked, according to the TATS national survey in Aboriginal Community Controlled Health Services.37 Most Aboriginal and Torres Strait Islander cannabis smokers mix cannabis with tobacco, so when asking about one, ask about the other.38
It is also important to ask all parents and carers of children whether they smoke and smoke inside the home or car.3 It is important to advise them to quit to protect their children, because not smoking inside reduces exposure to second-hand smoke, although it does not provide complete protection.39
For information about screening people who smoke for lung cancer, see Chapter 19: Cancer prevention and early detection, Lung cancer.
Behavioural
Advise
Advise all people who smoke to quit in a clear, non-confrontational way; for example, ‘The best thing you can do for your health is to quit the smokes’.3 Reviews of advice from doctors or nurses found increased cessation compared with usual care (RR 1.76 and 1.29 from 26 and 44 trials, respectively).5 This advice can be as brief as 30 seconds, and should be given at every visit and followed by offers of assistance to quit.22 Provide brief advice to all people who smoke, whether they want to quit or not; there is no need to first assess ‘stage of change’.22 More Aboriginal and Torres Strait Islander people who smoke daily and who had seen a health professional in the past year reported that they had been advised to quit (75%) than a similar sample of all Australians (56%).37 These Aboriginal and Torres Strait Islander people were 2.0-fold more likely to have made a quit attempt in the past year than those who did not recall having been advised to quit.
Advise all children who do not smoke to not start smoking. A review of 13 varied trials found these behavioural interventions among children aged 7–17 years reduced smoking initiation compared with control groups (RR 0.82).7 However, it is important to note that reducing smoking prevalence among parents and carers has the clearest impact of any intervention on preventing youth uptake of smoking.3 Approximately 70% of Aboriginal and Torres Strait Islander adults who have ever smoked daily started smoking before they turned 18 years of age, and approximately 30% started before age 15 years, although the proportion of children taking up smoking is declining.20
Help
Help all adults to quit by providing or referring to multisession behavioural support using individual or group counselling, Quitline, text messaging (eg QuitTxt), internet programs (eg QuitCoach or iCanQuit) or incentives for cessation support.
A network meta-analysis was confident that counselling increased cessation compared with no behavioural support (odds ratio 1.44 from 194 studies).8 More sessions of counselling and advice increase successful cessation.6,8 Four or more sessions have been recommended.22 Agree on a quit day, provide strategies for managing smoking triggers, mobilise support from family and friends and, at follow-up visits, provide encouragement and support, reviewing progress and problems.3 Allen Carr Easyway in-person group seminars are also effective.23 A meta-analysis of two randomised controlled trials (RCTs) at Aboriginal Community Controlled Health Services demonstrated that patients who were allocated to more intensive multisession face-to-face counselling and support were more likely to successfully quit than patients who received usual care (RR 2.36).40
Quitline (telephone 137848 or 13QUIT) offers cessation counselling from trained Aboriginal and Torres Strait Islander counsellors who will call the person who smokes and proactively provide follow-up telephone calls, following direct referral from a health practitioner or self-referral.3 Calling or being called by a telephone Quitline counsellor increases successful cessation (RR 1.38 and 1.25 from reviews of 14 and 65 trials, respectively). In the national TATS survey, 28% of Aboriginal and Torres Strait Islander people who had been advised to quit by a health professional reported being referred to Quitline, but only 16% of those referred actually talked to Quitline.37
Similarly, text messaging (eg QuitTxt), internet programs (eg QuitCoach or iCanQuit) and financial incentives are effective in increasing successful cessation (RR 1.54, 1.15 and 1.49 from reviews of 13, eight and 30 trials, respectively).
5 A New Zealand RCT of a text messaging intervention compared with a control (receiving no smoking information) found no significant difference in the greater smoking cessation at six weeks between Māori (RR 2.34) and non-Māori (RR 2.16).
41 In the national TATS survey, 27% of Aboriginal and Torres Strait Islander people who had been advised to quit by a health professional reported being referred to a quit-smoking website, but only 22% of those referred actually used the website.
37 There is variable interest in using financial incentives to support Aboriginal and Torres Strait Islander pregnant women to quit smoking, which is supported by the acceptability of a trial of incentives combined with other very intensive smoking cessation support for 22 rural Aboriginal women, but as yet no larger or RCTs.
42
Written self-help material (eg pamphlets) has only a minimal additional effect on successful smoking cessation, even though approximately half (49%) of Aboriginal and Torres Strait Islander people who had been advised to quit by a health professional reported being offered a pamphlet.
5,37 Similarly, carbon monoxide monitors (eg Smokerlyzer) are increasingly being used in this setting, but there is no evidence that this biofeedback increases smoking cessation in the pooled results from five trials in other settings.
43 Pooled evidence from five trials of smartphone apps found no additional impact on successful cessation compared with low-intensity support.
44 A pilot RCT of an app designed to help Aboriginal people to quit smoking only recruited 49 of the planned 200 participants, and only one participant had successfully stayed quit at six months.
45 Even though widely used in other settings, reviews have found no effect of acupuncture or hypnotherapy on successful smoking cessation. Exercise programs have many other positive impacts on health, but the pooled evidence from 21 trials found no impact on successful smoking cessation.

Medications
Help
Help non-pregnant adults to quit by offering smoking cessation pharmacotherapies to all nicotine-dependent people who smoke.
Nicotine dependence can be assessed by asking the following three questions:
- How soon after waking do you have your first cigarette?
- How many cigarettes do you have each day?
- Have you had cravings for a cigarette, or urges to smoke and withdrawal symptoms when you have tried to quit?Smoking within 30 minutes of waking, smoking more than 10 cigarettes per day and withdrawal symptoms are indicators of nicotine dependence.3
Reviews have found that all three smoking cessation pharmacotherapies available in Australia increase cessation compared with placebo or no drug: NRT (any form; RR 1.55 from 133 trials); varenicline (RR 2.24 from 27 trials); and bupropion (RR 1.64 from 46 trials).5 Combination NRT combines a patch with a faster-acting oral form (gum, spray, lozenge or inhaler) that can be used to deal with breakthrough cravings and withdrawal symptoms. Combination NRT is more effective than a single NRT (RR 1.25 from 14 trials).5 Shared decision making can help smokers to decide between the two most effective pharmacotherapies (varenicline and combination NRT) and involves patient preference and their past experience.3 A review of 65 trials found that providing behavioural support increased cessation compared with pharmacotherapy alone (RR 1.15).5
Aboriginal and Torres Strait Islander people who smoke daily are less likely to use NRT and other smoking cessation therapies than all Australians, even though they are just as likely to believe that these therapies help people quit smoking.46 These medicines can often be dispensed at no or reduced cost to Aboriginal and Torres Strait Islander patients, either through the Remote Area Aboriginal Health Service program in remote areas or elsewhere through the Closing the Gap Pharmaceutical Benefits Scheme co-payment measure.47
The benefit of vaping nicotine-containing e-cigarettes to help quitting remains contentious (for more information, see Chapter 2: Healthy living and health risks, Vaping). However, if the above pharmacotherapies are unsuccessful, consider the use of nicotine e-cigarettes after discussing the lack of information about the long-term risks of e-cigarettes.3 A review found nicotine-containing e-cigarettes increased cessation compared with behavioural or no support (RR 2.66 from seven trials) compared with non-nicotine e-cigarettes (ie placebo; RR 1.94 from trials), but the certainty of this evidence is limited by imprecision due to the small number of trials.9 The considerable variation between nicotine vaping products (including their nicotine dose) also increases uncertainty. The long-term health effects of vaping are uncertain, so dual use (smoking and vaping) and long-term vaping should be avoided.3
There is insufficient evidence that NRT is effective in increasing smoking cessation in pregnancy from reviews of only five placebo-controlled trials.5,48 It also remains unclear whether NRT is associated with any increase or decrease in adverse events in pregnancy. In contrast, a review of 97 trials found increased cessation in late pregnancy after behavioural interventions compared with minimal intervention or usual care (RR 1.35), and so behavioural interventions, such as CBT, remain the mainstay of cessation support in pregnancy.5 However, if counselling has not been successful, it is reasonable to consider intermittent-use formulations of NRT, such as gum, lozenges, inhaler or tablets, after explaining the risks and benefits.3 Do not use varenicline or bupropion in women who are pregnant or breastfeeding.3 (For more information about antenatal care, refer to Chapter 5: Preconception and pregnancy care, Pregnancy care).
There is insufficient evidence that cessation support is effective in children aged under 18 years. In a systematic review of primary care interventions for tobacco use prevention and cessation in children and adolescents, no difference was found between NRT patches and placebo in the nine trials of behavioural interventions and the single published trial.7 NRT may still be used following careful discussion with the patient (aged 12 years and over) and their carer, but varenicline and bupropion are not approved for use in people who smoke who are aged under 18 years.3
