Background: The coronavirus disease 2019 (COVID-19) pandemic had increased population-level anxiety and had elicited panic buying behaviour across the world. The over-hoarding of toilet paper has received a lot of negative public attention. In this work, we used Twitter data to qualitatively analyse tweets related to panic buying of toilet paper during the crisis. Methods: A total of 255,171 tweets were collected. Of these 4081 met our inclusion criteria and 100 tweets were randomly selected to develop a coding scheme in the initial phase. Random samples of tweets in folds of 100 were then qualitatively analysed in the focused coding phase until saturation was met at 500 tweets analysed. Results: Five key themes emerged: (1) humour or sarcasm, (2) marketing or profiteering, (3) opinion and emotions, (4) personal experience, and (5) support or information. About half of the tweets carried negative sentiments, expressing anger or frustration towards the deficiency of toilet paper and the frantic situation of toilet paper hoarding, which were among the most influential tweets. Discussion: Panic buying of toilet paper was seen during the 2020 pandemic period with a mass amount of related content spread across social media. The spontaneous contagion of fear and panic through social media could fuel psychological reactions in midst of crises. The high level of negative social media posts regarding the toilet paper crisis acts as an emotional trigger of public anxiety and panic. Conclusions: Social media data can provide rapid infodemiology of public mental health. In a pandemic or crisis situation, real-time data could be monitored and content-analysed for authorities to promptly address public concerns.

IntroductionThe rising popularity of TikTok among adolescents may influence their awareness and perceptions of e-cigarette use via user-generated content. This study aimed to examine how e-cigarette/vaping-related videos are portrayed on TikTok.MethodsThe nine most viewed hashtag based keywords were used to identify popular e-cigarette/vaping-related videos on TikTok (n=1000) from its inception (earliest upload date: January 2019) to November 2020. Five researchers independently coded the number of views, likes, user category and theme.ResultsA final sample of 808 e-cigarette/vaping-related videos that met study criteria were included. Collectively, these videos were viewed over 1.5 billion times, with a median view count of 1 000 000 (range 112 900–78 600 000) and a median ‘likes’ count of 143 000 (range 10 000–1 000 000). A majority of the videos portrayed e-cigarette use positively (63%; collectively viewed over 1.1 billion times). Neutral depictions of e-cigarette use were viewed a total of 290 million times (24%) and negative depictions of e-cigarettes were viewed a total of 193 million times (13%). The video themes included (not mutually exclusively): ‘comedy and joke’ (52%; total of 618 million views), ‘lifestyle and acceptability’ (35%; 459 million), ‘marketing’ (29%; 392 million), ‘vaping tricks’ (20%; 487 million), ‘nicotine and addiction’ (20%; 194 million), ‘creativity’ (16%; 322 million) and ‘warning’ (11%; 131 million).ConclusionOur findings illustrated that positively framed e-cigarette and vaping-related postings available without age restrictions on TikTok—a rising video-sharing platform that is popular among adolescents—have been viewed many times. Effective age restrictions are needed to reduce adolescents’ potential exposure to videos that portray vaping positively.

Background and AimsThere has been an increase in the potency of cannabis during the last two decades and adoption of a novel method of administration-vaping. YouTube, a social media platform, has become a popular source to access cannabis-related information. This study aimed to identify cannabis vaping YouTube videos from 2016 to 2020 and examine the themes and metrics. Design Cross-sectional sample of 200 YouTube videos. Setting YouTube, an on-line video sharing platform. Measurements Videos related to cannabis vaping were identified using the search terms:'vaping cannabis', 'vaping weed', 'vaping marijuana' and 'vaping THC' [tetrahydrocannabinol]. Videos were independently coded by two researchers. The number of views, likes, dislikes and comments were also collected. Robust regression was used to analyse the relationship between identified video themes and video metrics. Findings Six themes were identified: 'advertisement', 'product review', 'celebratory ', 'reflective', 'how-to' and 'warning'. The 'how-to' and 'celebratory' videos received the highest number of views and likes. The most popular video was viewed more than 4 000 000 times. Many videos portrayed risky behaviour (e.g. vaping a whole THC cartridge in a single setting). Fifty-two percent of these videos had no age access restrictions. The robust regression model also found that engagement metric was positively associated with 'reflective' videos and negatively associated with 'advertisement' videos. Conclusions A large number of videos on cannabis vaping are available on-line without age-restriction. Videos that portrayed risky behaviour appear to be prevalent.

Youth aged 16–24 years have the highest prevalence of mental illness in Australia, accounting for 26% of all mental illness. Youth mental health peer support work is a promising avenue of support for this population. However, limited research has examined impacts on those who provide youth mental health peer support work. We aimed to identify the benefits and challenges of working in a youth mental health peer support role. Semi-structured qualitative interviews with seven purposefully sampled peer workers from a national youth mental health organisation in Australia were conducted. The interviews were thematically analysed. Six key themes were identified: (1) personal growth, (2) interpersonal factors, (3) organisational factors, (4) boundaries, (5) role acknowledgement, and (6) challenging situations. Key supportive factors included financial reimbursement, training, support, and role-related flexibility. Identified challenges included lack of role acknowledgement, role-related stress, and boundaries. Operating within a youth mental health peer support role is perceived to have positive impacts on personal growth and interpersonal factors, enhanced through financial reimbursement, supervision, and role-related flexibility. Perspectives on the most effective form of role boundaries were diverse however their importance in addressing challenges was emphasised.
