These results describe how respondents say they put harm reduction into practice. Device choice, flavour, convenience and adequate nicotine delivery may affect whether an alternative is acceptable enough to replace smoking, but this survey cannot determine whether any one preference caused cessation or prevented relapse.
The 2026 Cochrane living systematic review reports high-certainty evidence that nicotine e-cigarettes help more people stop smoking for at least six months than nicotine-replacement therapy. That clinical evidence provides context for the surveyβs consumer pathways; it should not be treated as an efficacy estimate from this sample.
