Objective This systematic review on flavour capsule cigarettes aims to examine prevalence, correlates of use, behaviours and perceptions of these products globally.

Data sources A search of original, peer-reviewed research without restrictions in publication year, population, study design or language, using a combination of cigarette and capsule terms was conducted across four databases (Medline, Embase, Web of Science and Scopus), indexed until 30 April 2021.

Study selection Studies were included if they presented original, human subjects research on flavour capsule cigarettes.

Data extraction Two authors independently extracted data on main outcome results and assessed risk of bias using a validated quality assessment tool (QATSDD).

Data synthesis Of 842 unduplicated database records and four studies from citation searching screened, 20 studies were included in the review. Studies reported data from 2009 to 2019 across eight countries, the majority of which used cross-sectional or focus group study designs. Current capsule use among smokers was highest in Chile and Mexico (40%) and was associated with younger age, and in some countries, with being female. Capsule cigarettes are perceived as tasting better, being smoother on the throat, more fun to smoke, and more attractive compared with non-capsule cigarettes, particularly among susceptible non-smokers and non-daily smokers.

Conclusion Findings call for the adoption of comprehensive tobacco control policies that account for flavour capsules and similar iterations, which can increase appeal through flavours and innovative features. Continued monitoring and research of these products is critical, with particular attention to low-income and middle-income countries, which make up a disproportionately larger share of the capsule market.
