Nicotine is a vasoconstrictor, which means it narrows blood vessels wherever it makes contact, and gum tissue is dense with tiny ones right at the surface. When those vessels narrow, that patch gets less blood than it should, which means less oxygen and fewer of the materials tissue needs to repair itself.

Nicotine pouches are alkaline by design. A higher pH pushes nicotine through the tissue faster. Hold that against one spot for hours a day and you shift the bacterial balance there and keep the contact point irritated.

I'd switched off vaping because I thought I'd traded up to the harmless option.

What I'd actually done was concentrate the exposure into one square centimeter of my mouth and hold it there all day, in a mouth producing less of the thing meant to protect it.

Then there's what nicotine does to saliva. It cuts the flow. And saliva is the thing that neutralizes acid after you eat.

The pouch isn't sitting there passively. It's a fiber fleece that absorbs moisture and swells as it hydrates, so it firms up and presses outward into your gum over the 20 to 60 minutes it's in.

So the tissue underneath gets squeezed from the outside while the nicotine narrows the vessels from the inside.

It Started as the Norm

I picked up nicotine pouches right out of college because all my frat brothers were doing it. Being on the hockey and baseball teams, half the locker room had a can in their bag.

Then I took a fintech job in SF and it went from a habit to infrastructure.

The entire sales floor ran on them.

Pouch before the standup, pouch before every call, pouch in the elevator.

High stress, long hours, and a room full of guys doing the exact same thing.

Nobody questioned it because everybody did it.

The Downside I Didn't See

Which is the part that still gets me. I'd never touched a cigarette in my life. I genuinely believed I'd found the version with no downside.

Once I started paying attention, I realized how much I'd been writing off.

Dry Mouth Turned Into Sensitivity

The dry mouth was constant. My tongue stuck to the roof of my mouth. I was refilling my water bottle 5 times a day.

Then came the sensitivity. That's what less saliva does over time. Acid sits on your enamel longer, and bacteria stick around instead of getting rinsed off. Enamel wears thin, and eventually you feel it.

My Heart Rate Increased

My resting heart rate had climbed it'd be pounding at my desk. Cardio also started feeling like quicksand because I no longer had the stamina. Turns out the reason is simple. Nicotine triggers a stress response that pushes out adrenaline, which speeds your heart up and narrows your blood vessels, so your heart is working harder against more resistance.

I Was Downright Addicted

Basically I had to have one on my gums with everything I did, and it was my morning ritual just to feel remotely awake.

Nicotine floods your brain with dopamine, and your brain adapts by building more receptors for it, which is why you need more to get the same thing. It also stops producing as much on its own, so when the nicotine wears off you're anxious and irritable and reaching for another one just to get back to baseline.

That's why cold turkey was never going to work for me.

I wasn't fighting a craving, I was trying to remove the thing my entire day had been built around.

Nobody was making one that handled both.
