New Discoveries
Mass Spectrometry Revelations From (Last Week's Guest) Ben Katz Help *Halt* ZYN Nicotine Pouch Sales
Last week, tobacco giant Philip Morris announced it was halting online sales of its wildly popular nicotine pouches, ZYN (131.6 million cans were shipped to the U.S. during Q1 of 2024).
Recently, the Wall Street Journal joined forces with my guest on the podcast last Thursday, mass spectrometrist Ben Katz, to expose what's *really* in ZYN's nicotine pouches (I highly recommend checking out his fascinating Instagram and YouTube channels, where he analyzes all types of products).
Mass spectrometry is an analytical tool useful for identifying and analyzing chemical compounds by measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample. These measurements can be used to calculate the exact molecular weight of the sample components as well, thus exposing information that might not be represented on a product's label.
In his feature with the Wall Street Journal (you can watch the video that he appears in here or check out the full article here), Ben found that nicotine is the only tobacco-related alkaloid in ZYN, along with cellulose (wood pulp), artificial sweeteners, and flavorings. The problem is that the synthetic cooling agents in ZYN, while not explicitly advertised as flavors, also contribute to taste perception and may therefore be affected by the ban on flavoring agents (you can read more about this issue here).
But despite them being healthier than vape pens, which I discussed in my podcast with Ben, the issue with flavored tobacco products, including flavored nicotine pouches like those offered by ZYN, lies in their appeal to young people and the potential health risks associated with their use. Flavors can make these products more attractive and palatable, especially to young users, potentially leading to increased use. Concerns also arise regarding the impact of these products on public health, particularly in terms of addiction and long-term health outcomes.
Washington D.C. banned flavored tobacco products, including flavored synthetic nicotine products, in 2022 to address these concerns. The aim is to reduce the use of nicotine and tobacco products, especially among teens, to prevent the potential gateway effect to traditional tobacco use and mitigate associated health risks.
After the Wall Street Journal's exposé with Ben was published, and as media attention on ZYN's products continued to intensify, Washington D.C. delivered a subpoena to Philip Morris related to the company's refusal to comply with the 2022 ban. This resulted in the company's announcement to halt online sales of the product.
You can catch Ben's reaction video to the news here!
Also, the podcast we released together last week is extremely interesting and insightful — I had Ben analyze two of the products I get asked about the most: Feel Free, a bottled blend of kratom and kava (video here), and Lucy nicotine gum (video here).

Kion Product of the Week: Kion Medium Roast Coffee
Many of us cherish our morning coffee ritual, but sometimes coffee doesn’t reciprocate the love. It’s not uncommon to experience jitters, headaches, or sinus issues after a cup.
But fear not — it’s not you, it’s your coffee. Over 97% of the world’s coffee falls into the “commercial coffee” category — mass-produced, sprayed with pesticides, and often prone to mold growth. These factors can lead to health concerns and a less-than-satisfactory brew.
At Kion, we believe you deserve better. Elevate your daily grind with the pure pleasure of Kion Medium Roast Coffee. Whether you prefer Whole Bean or Ground, our coffee sets the bar high for both health and taste.
Certified organic and rigorously tested for toxins, Kion Coffee is ethically sourced to ensure every sip is a moment of pure delight. It's fresh, bold, and impressively smooth — and it not only tastes exceptional but also makes you feel amazing.
Every batch of Kion Coffee features 100% organic Arabica beans sourced from sustainable, fair-trade cooperatives. We meticulously test for mold, mycotoxins, and pesticides to ensure unparalleled quality and purity. Our medium roast boasts a balanced, clean flavor with a smooth, rich body. From sweet apple and marzipan to baking spices and dark chocolate, each sip reveals layers of scrumptious complexity.
