Big Tobacco has found its next growth engine in nicotine pouches — good for company profits, bad for users, since nobody knows yet what a 16-hour-a-day nicotine drip does to the heart.

• Pouches slip under the lip, leave no smell or cloud, and deliver twice the nicotine of a cigarette, so people keep them in all day and even while asleep.
• Most pouch brands, including Zyn, are owned by the same tobacco giants that sell cigarettes and vapes, and smoke-free products now make up close to 40% of Philip Morris revenue.
• The tax gap is the real loophole: every state taxes cigarettes and most tax vapes, but pouches escape extra tax in more than half the country, making them the cheapest way to stay addicted.
• Vaping's damage shows up in the lungs, with asthma flare-ups, pregnancy risks, and rare severe pneumonia cases; pouches skip the lungs but load the cardiovascular system with a constant stimulant.
• Poison control cases of children swallowing pouches found at home have exploded since 2020, and early users report gum damage and white patches in the mouth.

Outlook: Expect states to start closing the pouch tax gap while long-term heart and mouth-cancer data stays years away.
