âThe use of comedy, lifestyle references, nicotine addiction references, vaping tricks and âhow toâ tutorials may create social norms around vaping and increase its social acceptance,â the researchers concluded. âConsidering vaping-related videos are widely accessible on TikTok, there is an urgent need to consider age restrictions to reduce youth uptake.â They suggested that vaping videos on TikTok might reach a wider audience than on other video-sharing platforms as a result of its recommendation algorithm. Tianze Sun, a PhD student at UQ and the studyâs first author, said the researchers were interested in looking at how e-cigarette use was portrayed on TikTok, given the appâs popularity among young people.
