*Three participants reported using pod devices in the past but were not currently using at the time of the interview.
†Participants reporting non-daily pod device use did not own their devices and instead shared with a friend.
‡Participants were presented with descriptions and pictures of small, medium and large e-cigarettes. Small devices consisted of disposable and rechargeable ‘cigalikes’. Medium devices consisted of vapour pens. Large devices contained refillable tanks and included ‘box mods’.
§Participant did not provide a brand name, but physical description of device and flavour options was consistent with My Von Erl.
