RT Journal Article SR Electronic T1 Use and reasons for use of electronic vapour products shaped like USB flash drives among a national sample of adults JF Tobacco Control JO Tob Control FD BMJ Publishing Group Ltd SP 685 OP 688 DO 10.1136/tobaccocontrol-2019-054932 VO 28 IS 6 A1 Kristy L Marynak A1 Fatma Romeh M Ali A1 Gillian L Schauer A1 Michael A Tynan A1 Brian A King YR 2019 UL http://tobaccocontrol.bmj.com/content/28/6/685.abstract AB Objectives Assess use and reasons for use of electronic vapour products (EVPs) shaped like universal serial bus (USB) flash drives among adults in the USA.Methods Data came from SummerStyles, an internet survey of US adults aged ≥18 (N=4088) fielded in June to July 2018. Respondents were shown product images and asked about ever use, current (past 30 days) use and reasons for use. Weighted point estimates and adjusted ORs were assessed.Results In 2018, 7.9% of participants had ever used flash drive-shaped EVPs, including 25.7% of current cigarette smokers and 45.9% of current EVP users. Moreover, 2.0% reported current use, including 6.8% of cigarette smokers and 34.3% of EVP users. Leading reasons for ever use were ‘to deliver nicotine’ (30.7%) and ‘friend or family member used them’ (30.2%).Conclusions About one in 13 US adults have ever used flash drive-shaped EVPs, with use being highest among current EVP users. Nicotine content and friend/family use are drivers of ever use.Public health implications Understanding use of emerging EVP types can inform strategies to maximise any potential benefits for adult cessation and minimise risks of youth initiation.
