Warning about Zyn nicotine pouches
Zyn nicotine pouches are being called "gas station Ozempic.". But using these nicotine pouches can be addictive and possibly hazardous to your health.

"Nicotine hiccups" sound made up. But experts say they're a real phenomenon.
Recent data on drug side effects found that nicotine was associated with the hiccups, according to a 2021 study looking at the Food and Drug Administration's adverse-event reporting system (FAERS).
And anecdotal evidence shows many nicotine users can relate, said Melissa Little, director of the Center for Nicotine and Tobacco Research at the University of Virginia School of Medicine. On TikTok, Reddit and elsewhere online, Zyn users and people who vape are comparing notes on their "niccups."
"Why do Zyns and nicotine pouches give me hiccups every time?" TikTok user @callmecarolyn asked her followers, before cutting to a scene of her hiccuping in bed.
Well, here's why.
More: FDA seeks to limit nicotine in cigarettes, most cigars. Vapes and Zyn are excluded.
Nicotine acts by binding to receptors in the brain and nervous system, Little said. When these receptors are activated, they release neurotransmitters throughout the body. One of these neurotransmitters, called dopamine, plays a role in regulating the phrenic nerve, which controls breathing in the diaphragm.
'Instead of them doing what they usually do, they get a little messed up and get activated in certain ways,' Little said. 'And that can induce hiccups.'
Nicotine can also irritate the mucus membrane that aligns the throat and esophagus, which can lead to hiccups, she said. It can also stimulate stomach acid production and can cause reflux, triggering more hiccups.
The Centers for Disease Control and Prevention says nicotine is a highly addictive substance found in tobacco products, such as cigarettes, and nicotine replacement therapies, like nicotine gum.
Tobacco use among middle and high school students has decreased from 2023 to 2024, predominately due to a decline in e-cigarette use, according to the 2024 Annual National Youth Tobacco Survey.
However, nicotine pouch use saw a slight uptick from 1.5% in 2023 to 1.8% in 2024. Sales also increased from 126 million pouches in August 2019 to 808 million in March 2022, according to the CDC.
Nicotine pouches, sometimes referred to as 'lip pillow' or 'upper decker,' are placed between the lip and gum, according to the American Lung Association. They're similar to snus, which are oral pouches containing shredded tobacco leaf, except nicotine pouches contain nicotine powder. They come in several flavors and are available at different nicotine strengths.
Zyn is the only brand of nicotine pouches that has received marketing authorization for many of its products for consumers 21 and older. The agency said in a statement that Zyn products pose a lower risk of cancer and other serious health conditions than cigarettes and most smokeless tobacco products due to substantially lower amounts of harmful constituents.
Nicotine in adolescence can harm the parts of the brain that control attention, learning, mood and impulse control, the CDC said.

The troubling truth behind ‘toxic' chemicals found on receipts — and whether they're actually killing you: doctor
QUESTION: Hi Dr Zac, I recently saw a viral video claiming the ATO is 'killing us softly' through thermal receipts – apparently they're coated in BPA and other hormone-disrupting chemicals. As someone who handles receipts at work all day (shoutout to retail life), I'm now kind of freaked out. Should we be worried about the long-term effects of touching them, or is this another TikTok conspiracy? – Jodie, 34, Wollongong NSW ANSWER: Hi Jodie, Good news – for once, TikTok has stumbled onto some real science. Thermal receipts – those shiny ones that fade faster than a politician's promise – often contain Bisphenol A (BPA) or its chemical sibling, BPS. These compounds are used in thermal printing to create text without ink. But here's the rub: both are known endocrine disrupters, meaning they can interfere with your hormones, especially estrogen (National Health and Medical Research Council, 2020). Advertisement What's more worrying is that BPA can be absorbed through the skin. A 2014 study in Environmental Health Perspectives found that people who handled receipts frequently – particularly with moisturised or greasy hands – absorbed measurable amounts of BPA. Another Australian study confirmed that regular skin contact can lead to significant exposure. Now, don't panic and start wrapping your hands in cling wrap. Most of the alarming research involves high-dose exposure, usually in industrial settings or lab environments. But for retail and hospitality workers handling receipts every day, the cumulative effect is something to take seriously. So how can you protect yourself without quitting your job or demanding a full PPE kit? Chemicals on store receipts often contain chemicals that can disrupt your hormones, according to Dr. Zac Turner. Vladimir Razgulyaev – 1. Wash your hands — and skip the wipes Advertisement Regular soap and water is more effective than antibacterial wipes when it comes to removing BPA residue. Easy, quick, and no need to buy anything fancy. 2. Keep your hands away from your face BPA doesn't need an invitation to hop from your fingertips to your mouth or eyes. Less contact, less risk. BPA chemicals can be absorbed through the skin. ViDi Studio – 3. Wear gloves if you're pregnant or working full-time with receipts Especially in busy environments where they're flying out like confetti. Disposable gloves can make a real difference — and no, they don't make you look ridiculous. 4. Go digital Advertisement If you're the customer, skip the paper. Most retailers now offer email or text receipts. It's cleaner, safer, and you'll stop collecting receipts for things you returned two months ago. 5. Don't be fooled by 'BPA-free' Many retailers have switched to BPS-coated paper instead. But early research suggests BPS may be just as hormonally active – possibly worse in some cases. So it's a bit like replacing cigarettes with cigars and calling it progress. Ultimately, we need broader changes – better regulation and safer materials. France banned BPA receipts in 2019. Australia's not there yet, but retail workers like you raising concerns is how change starts. Advertisement So yes, Jodie, your instincts were right. This isn't conspiracy – it's chemistry. And when it comes to protecting your hormones, even small changes count. Stay sharp, Dr Zac

How social media fuels teen anxiety
Social media was meant to help us feel more connected, but for today's teens, it's often doing the opposite. While apps like Instagram, TikTok, and Snapchat offer opportunities for self-expression, they can also fuel anxiety, low self-esteem, and distorted self-image. For parents and caregivers, it's important to understand how these platforms are shaping teen mental health and what we can do to support our kids. The rise of the curated self According to the U.S. Surgeon General's 2023 advisory on social media and youth mental health, up to 95% of teens between 13 and 17 use social media, and more than a third report using it 'almost constantly.' With so much of their social world playing out online, teens are under pressure to present a version of themselves that is always interesting, attractive, and liked. But this constant self-monitoring takes a toll. The same advisory warns that more than three hours of daily social media use is linked to a doubled risk of anxiety and depression in adolescents. Social media's impact on teen mental health Social media isn't just a tool. It's an environment that shapes how young people see themselves and others. Studies show that heavy use is associated with rising rates of anxiety, depressive symptoms, and feelings of isolation. A 2023 CDC Youth Risk Behavior Survey found that 53% of teen girls reported feeling persistently sad or hopeless during the past year. While this is a slight improvement over the 2021 survey, this figure is still alarming. Experts cite social comparison, how teens measure their appearance, popularity, and worth against what they see online, as a key contributor. Platforms encourage comparison by rewarding curated, idealized content. Photos are filtered, moments are staged, and metrics like likes and comments become a stand-in for social validation. For teens still figuring out who they are, this can create a crushing sense of inadequacy. In fact, the Surgeon General's 2023 advisory highlights that nearly half of adolescents, especially girls, say social media makes them feel worse about their bodies. More: What parents should know about teen screen time and mental health | Parentally Speaking When 'normal' becomes toxic Not all screen time is harmful. Teens use social media to stay connected, learn new skills, and express themselves. But when the need to maintain a perfect image becomes constant, the pressure builds. Here are a few ways social media can worsen teen anxiety: Fear of missing out (FOMO): Seeing friends post about events or trips they weren't invited to can trigger exclusion and sadness. Perfectionism: Teens may feel they have to edit photos, delete posts that don't get enough likes, or constantly monitor their digital image. Cyberbullying: Negative comments or targeted harassment online can leave lasting emotional scars, and it often happens out of view from adults. Sleep disruption: Notifications and compulsive scrolling often cut into rest, which is directly tied to emotional regulation and resilience. What parents can do The goal isn't to ban social media. It's to help teens build a healthy, balanced relationship with it. Here's how you can start: Talk openly about what they're seeing online. Ask questions like: 'Have you seen anything online that made you feel bad about yourself?' or 'How do you decide what to post?' These conversations normalize critical thinking and self-reflection. Model real-life balance. Your own phone habits send a powerful message. Prioritize device-free meals, get outside together, and talk about your own digital boundaries. Encourage offline confidence-builders. Whether it's sports, art, volunteering, or in-person hangouts, help teens develop a sense of worth that isn't tied to likes or followers. Set limits collaboratively. Instead of imposing blanket restrictions, work with your teen to create screen-time agreements that make sense for your household. This builds trust and accountability. Let them know they're enough. Reassure them that they don't need to be perfect to be valued. Praise effort, empathy, and character, not just appearance or performance. At Wellspring Center for Prevention, we believe emotional resilience starts at home with informed, supportive families who understand the challenges of growing up in a digital world. By staying present, fostering open communication, and setting tech boundaries with compassion, parents can help their teens navigate the pressures of social media without losing sight of who they really are. Sean Peek is the Director of Marketing at Wellspring Center for Prevention, a nonprofit focused on substance use prevention and mental health in New Jersey. He works to empower families and communities through education, storytelling, and strategic outreach.
