To the Editor: In March 2008, nicotine patches (15 mg per 16 hours) were authority-listed for Aboriginal and Torres Strait Islander people by the Pharmaceutical Benefits Advisory Committee (PBAC) as part of efforts to improve access to medications.1,2 Although timely and welcome, the decision to list only 15 mg patches should be revisited, as it is not consistent with current smoking cessation clinical guidelines.3-5 Neither is it consistent with evidence from a 2008 tobacco survey that we conducted in remote Aboriginal communities in Arnhem Land, Northern Territory.
Clinical guidelines advise that smokers will require more intensive support to quit smoking if they: (i) demonstrate a high level of dependency; (ii) have had more than one short quit attempt; (iii) still smoke or experience cravings when using nicotine replacement therapy (NRT); and/or (iv) are frequently exposed to other smokers.3,4 This support includes appropriate medication and counselling, which are more effective in combination.5 Under-dosing is a common problem, given that NRT products deliver nicotine plasma levels well below that delivered by a cigarette.3 Higher-dose NRT products (eg, 4 mg gum) or combination nicotine therapies (eg, patches with gums) are effective for highly dependent smokers.3,5
In the Arnhem Land survey, we interviewed 397 people (aged ≥ 16 years) about tobacco. Of these, 77% were current smokers. Among the current smokers, 17% were attempting to quit or had tried to quit, and 58% were contemplating quitting. Dependency was common, with 55% of smokers reporting they smoked first thing in the morning or during the night. With many dependent smokers, high rates of smoking and widespread “cue” exposure, there is a high need for intensive quit support.
We also interviewed 24 smokers interested in quitting who were offered 21 mg patches, and 4 mg and 2 mg gums and lozenges. All used the gums; four combined gum with 21 mg patches, with one of these initially trying lozenges. Modest increases in periods of abstinence and reduction in daily consumption were documented in the 11 participants followed up so far. This evidence, albeit limited, challenges the PBAC rationale for listing patches but not gums for Aboriginal and Torres Strait Islander people, namely: “this population eschews oral aids for smoking cessation”.1
Some Aboriginal and Torres Strait Islander smokers wanting to quit may benefit from combination NRT or gums alone. A wider range of NRT products including gums should therefore be considered by the PBAC.
