#Discreetshipping: Selling E-cigarettes on TikTok.

Introduction: Youth and young adult use of e-cigarette products continues to remain high despite regulatory approaches to reduce youth access. This study sought to examine TikTok content regarding the sale and distribution of e-cigarettes.

Aims and methods: TikTok videos (n = 475) and metadata posted between June 2022 and August 2023 were scraped using a TikTok application programming interface and popular hashtags used to sell vaping products (ie, #discreetshipping [40.8 million], #puffbundle [14.8 million], #hiddennic [1.0 million]). After watching the 25 most viewed videos (39 600-868 800 views), a codebook was developed. All metadata were annotated using 11 unique codes: Small business, brand, cannabis, bundled, hidden, fake, international sales, no ID, order via Instagram, order via another method, and cost.

Results: Overall, 367 videos (with an average of 2017 likes) were deemed relevant. Videos advertised popular vaping brands (50.4%) that included cannabis products (45%). Products were described as bundled (28.6%), hidden (8.7%), and able to be shipped internationally (6%) without age verification (45.2%). Some videos (8.2%) evaded algorithms' detection of illegal activity by describing the post as "Fake." Customers were directed to other social media platforms (most often Instagram, 57.5%) and/or other websites/links (58.3%) to purchase products; 22.1% advertised discounts, free shipping, or low costs (ranging from $25-$35).

Conclusions: Social media platforms, such as TikTok and Instagram, are being used to circumvent e-cigarette regulatory policies. Regulatory agencies should expand enforcement strategies to include social media platforms where users are illegally selling and distributing e-cigarettes internationally to young audiences.

Implications: TikTok users across the globe are violating local, state, and federal laws by selling e-cigarettes concealed inside other products or bundled in packages that avoid detection. TikTok videos posted by self-proclaimed small business owners advertise discreet shipping practices that evade age verification in order to sell nicotine and cannabis bundles worldwide. Accounts used phrases describing the post to be "fake" to avoid detection by algorithms or TikTok administrators. E-cigarette regulatory agencies can partner with social media platforms to close regulatory gaps.
