Are Nicotine Pouches Safe? Side Effects & Long-Term Use

• Short-term side effects of nicotine pouches can include gum irritation, dizziness, and increased heart rate
• Side effects are more common for new users or those using high-strength pouches
• Hiccups and nausea can also occur
• Long-term effects of nicotine pouches are still being researched

Tobacco-free nicotine pouches contain nicotine, which is an addictive substance. 

Nicotine itself can cause short-term effects, especially for those who are new to using pouches or have chosen a strength that’s higher than their tolerance. These side effects are typically mild and temporary.

There are four areas where users may typically experience side effects related to nicotine pouches:

• Mouth and gums (gum irritation, tingling sensation)
• Cardiovascular health (increased heart rate)
• Stomach and digestion (stomach irritation or nausea)
• Brain (dizziness)

Some users report a tingling or burning sensation where the pouch rests. 

Research supports that gum irritation or redness can occur from frequent use.¹ This happens because nicotine (and the pouch’s flavourings) can be slightly harsh on sensitive mouth tissues.

Dry mouth is another common effect, as nicotine can reduce saliva production.

A recurring question is, “Does nicotine increase blood pressure”?

Nicotine is a stimulant and can temporarily increase heart rate and blood pressure. This response is linked to the body’s “fight or flight” reaction.²

According to the British Heart Foundation, nicotine “does not cause acute cardiac events or coronary heart disease…[but] it raises the heart rate.”³

The BHF continues: “Nicotine…is not a significant health hazard for people without heart conditions. But nicotine is a problem for people with heart disease.”

Some people feel mild stomach upset, nausea, or even hiccups. This can happen if nicotine is swallowed in the saliva, or if the pouch strength is higher than the body is used to.

Feelings of dizziness or a light-headed “buzz” can occur, especially for new users or when using a stronger pouch.

This effect, sometimes referred to as a “nicotine buzz” or “nicotine rush”, has been associated with nicotine’s stimulant properties. Some users report that this sensation feels strongest during initial use and may vary over time.

Yes. Nicotine temporarily increases blood pressure.²

This happens because nicotine acts as a stimulant and triggers the release of norepinephrine, which makes your heart beat faster and blood vessels tighten.

If you’re wondering “why do nicotine pouches give me hiccups?”, this sensation can occur due to the pouch slightly irritating the throat or stimulating swallowing muscles.

This effect is usually short-lived and goes away once the pouch is removed.

Some users also ask: “Why do nicotine pouches make me feel sick?” Feeling queasy or nauseous may occur if the pouch strength is higher than your tolerance, if you’re using pouches on an empty stomach, or if nicotine is swallowed with saliva.

These sensations are linked to nicotine’s stimulant effects and typically ease once your body adjusts.

To reduce both hiccups and nausea, see the section on Tips for Responsible Pouch Use.

Because nicotine pouches are relatively new compared to cigarettes or chewing tobacco, research on the long-term effects of using nicotine pouches is ongoing and knowledge gaps remain.

Current studies mainly highlight nicotine’s addictive properties and the potential for ongoing oral irritation.

Nicotine pouches do not involve burning or inhalation, so they avoid the smoke and toxic chemicals associated with smoking.

According to the NHS, it is these chemicals in cigarette smoke which are linked to cancer, heart disease, and respiratory problems.⁴

However, nicotine pouches still contain nicotine, which is an addictive substance.

There are several things you can try if you want to reduce any perceived side effects of nicotine pouches:

• Opt for a lower pouch strength (such as 0–6 mg). 
• Avoid using on an empty stomach.
• Only use one pouch at a time.
• Drink water during or after use to help relieve dry mouth or throat. 
• Rotate pouch placement to help reduce local irritation. 
• Good oral hygiene is recommended when using nicotine pouches regularly.
• Try different brands and flavours to find what feels best.

You may also want to consider how many nicotine pouches a day you are using.

At Northerner, we make sure every nicotine pouch in our range is carefully tested to meet strict quality standards. All nicotine pouch products are tested through NicoLeaks, an independent programme run with Eurofins laboratories.

These lab-tested pouches are analysed for nicotine strength and pH levels to ensure consistency and transparency for our customers.

Nicotine pouches are a tobacco-free and discreet way of using nicotine, but they are not risk-free. They can cause short-term side effects and may contribute to long-term oral irritation. 

Research is ongoing into other long-term effects. For further guidance, it’s recommended to speak with a healthcare professional.
