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

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

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

In a 2025 briefing, Action on Smoking and Health (ASH) wrote:⁵

“The research consensus is that nicotine does not cause cancer, nor is it linked in isolation to most of the diseases that smoking causes.”

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

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

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

This is a commonly searched query online, for example by people who search for “PABLO side effects” and “VELO nicotine pouches side effects”.

These side effects are typically mild and temporary.

There are four key areas where users may typically experience side effects of nicotine pouches:

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

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

Research supports that gum irritation or redness can occur from frequent nicotine pouch use.¹

This happens because nicotine (and other nicotine pouch ingredients like flavourings) can be slightly harsh on sensitive mouth tissues.

Dry mouth is another common effect, as nicotine can reduce saliva production.⁶

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

Nicotine can temporarily increase heart rate and blood pressure because it activates the sympathetic nervous system, which is responsible for the body's fight or flight response.²

According to the British Heart Foundation, nicotine:³

“does not cause acute cardiac events or coronary heart disease…[but] it raises the heart rate. 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.

Find out more in our guide “What Is a Nicotine Rush?”

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. How long they last can vary depending on the user–learn more about how long nicotine stays in your system.

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

Some users wonder whether nicotine affects skin health.

While research is still developing, nicotine may influence blood flow and inflammation, meaning there can be a link between nicotine and acne for some users.

There are several factors that may contribute to stronger nicotine pouch side effects:

• Nicotine content
• Pouch moisture levels
• Nicotine release speed

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.

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. 
• Avoid using on an empty stomach.
• Only use one pouch at a time.
• Drink water during or after use.
• Rotate pouch placement to help reduce local irritation. 
• Practice good oral hygiene.
• 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 maintain high quality standards. Nicotine pouches are routinely tested with Eurofins laboratories, with results published on Nicoleaks. 

Tests include analyses for nicotine and pH levels to ensure 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.
