 The study aimed to assess the characteristics of content on TikTok associated with the hashtag hashtag Nixic, which is used to discuss nicotine adverse events. The results showed that more than one-third of nicotine poisoning related content portrayed active vaping behavior and 43% of recorded users self-reported experiencing nicotine sickness or adverse events. The study suggests that digital surveillance on emerging social media platforms, such as TikTok, may be useful for monitoring vaping adverse events, particularly among youth and young adults.
