In the USA, this has raised regulatory challenges for the Food and Drug Administration (FDA). For instance, the introduction of pod-based e-cigarette devices like JUUL <a href=\"https:\/\/jamanetwork.com\/journals\/jamapediatrics\/fullarticle\/2759022\" target=\"_blank\" rel=\"noopener\">led to huge increases in youth e-cigarette use<\/a>.<\/p>\n<p>The FDA\u2019s ban on flavored cartridge-based e-cigarettes in 2020 to counter the popularity of these pod devices among youth led to an <a href=\"https:\/\/www.cdc.gov\/mmwr\/volumes\/69\/wr\/mm6937e1.htm\" target=\"_blank\" rel=\"noopener\">upsurge in youth use of \u201cdisposable pod devices\u201d<\/a> (e.g. Puff Bar, Eon Stik) not covered by the ban. More recently, Puff Bar devices reappeared on the market in February 2021 (after being removed in 2020 in response to FDA warnings) claiming that their product now has tobacco-free nicotine (TFN). According to Puff Bar, TFN refers to nicotine not derived from a tobacco product but produced through a \u201cpatented manufacturing process\u201d.<\/p>\n<figure id=\"attachment_1589\" aria-describedby=\"caption-attachment-1589\" style=\"width: 640px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1589 size-large\" src=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1-1024x427.png\" alt=\"\" width=\"640\" height=\"267\" srcset=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1-1024x427.png 1024w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1-300x125.png 300w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1-768x320.png 768w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1-640x267.png 640w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-1.png 1074w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><figcaption id=\"caption-attachment-1589\" class=\"wp-caption-text\">Description of Tobacco Free Nicotine (TFN) on Puff Bar&#8217;s website, April 2021. Source: https:\/\/puffbar.com\/pages\/about-puff-bar<\/figcaption><\/figure>\n<p>However, Puff Bar is not alone in claiming use of \u201csynthetic\u201d nicotine. To assess the presence of TFN products, we searched for \u201ctobacco free nicotine\u201d and \u201csynthetic nicotine\u201d on 12 online e-cigarette retailer websites in April 2021 (excluding websites that only sold e-liquids). We also assessed other constituents (flavors, nicotine concentration) and marketing claims of TFN products on these websites. We observed that 10 out of 12 online retailers sold e-cigarette products that they claimed contained TFN. Brands that sold TFN e-liquids only were: Air Factory, Aqua Vape, BLVK, Cloud Nurdz, Five Pawns, Glas, Mega Milk, Moo E-liquids, and Zooka. Brands including BluBar, Cali Bar, Exotic Bar, Ignite, Pachamacha, and Puff Labs sold TFN disposable pod devices; Dinner Lady sold TFN e-liquids and disposable devices; Glas sold TFN e-liquids and closed cartridge pod devices; and Riptide sold closed cartridge pods.<\/p>\n<p>TFN nicotine was available in both freebase and nicotine salt with a range of nicotine concentrations (0-50mg\/ml) and flavors (fruit, candy, dessert, coffee, vanilla, menthol, \u201cice\u201d, and tobacco). The TFN brand\/retailer websites claimed that relative to tobacco derived nicotine, TFN was cleaner, purer, has higher quality, tastier, and represented a \u201csophisticated vaping experience\u201d.<\/p>\n<p>These synthetic TFN e-cigarette products present a quandary for FDA regulations. The Tobacco Control Act (2009) gave the FDA jurisdiction over tobacco products that contain nicotine derived from tobacco, however it is unclear if TFN falls under FDA\u2019s regulatory jurisdiction. It is critically important to also note that the term TFN is being used to refer to both nicotine derived through a synthetic process, as well as nicotine that is derived from tobacco but is purified to remove everything except nicotine. For example, newer TFN nicotine pouches like Zyn and Velo, <a href=\"https:\/\/truthinitiative.org\/research-resources\/emerging-tobacco-products\/what-zyn-and-what-are-oral-nicotine-pouches\" target=\"_blank\" rel=\"noopener\">which are becoming popular among youth<\/a> claim that they contain purified nicotine derived from tobacco, while other nicotine pouches like NIIN and 2ONE claim that they contain nicotine not derived from tobacco.<\/p>\n<figure id=\"attachment_1590\" aria-describedby=\"caption-attachment-1590\" style=\"width: 640px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1590 size-large\" src=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a-1024x410.png\" alt=\"\" width=\"640\" height=\"256\" srcset=\"https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a-1024x410.png 1024w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a-300x120.png 300w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a-768x307.png 768w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a-640x256.png 640w, https:\/\/blogs.bmj.com\/tc\/files\/2021\/07\/TFN-image-2-a.png 1280w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><figcaption id=\"caption-attachment-1590\" class=\"wp-caption-text\">Example 1: Velo&#8217;s website.
