If you run — whether that’s casual 5Ks, long weekend miles, or structured training — you’ve probably wondered how nicotine fits into the picture.
In the UK, when runners ask about “snus”, they’re almost always talking about tobacco-free nicotine pouches, not traditional tobacco snus.
The big question:
Will nicotine pouches affect my running performance?
The honest answer is yes — they can — but how much depends on timing, strength, and your own tolerance.
Quick context: Nicotine pouches deliver nicotine without smoke or combustion, which already puts them in a very different category from cigarettes.
How nicotine affects the body during running
Nicotine is a stimulant. That means it directly affects the cardiovascular and nervous systems — both of which matter when you’re running.
After using a nicotine pouch, you may experience:
- Increased heart rate
- Higher blood pressure
- Adrenaline release
- Slight narrowing of blood vessels
For short efforts, this can feel manageable. Over longer distances, it often becomes noticeable.
Can nicotine ever feel helpful?
Some runners report improved focus or alertness after nicotine use — particularly during short, easy runs.
This effect is more commonly reported with lower-strength pouches, such as those found in low nicotine pouch ranges.
That said, nicotine is not an endurance enhancer, and any perceived benefit is usually short-lived.
Where nicotine can hurt your running
1. Elevated heart rate
Nicotine raises your baseline heart rate. When you start running, this means you’re already closer to your upper zones.
This is especially noticeable with strong or extra-strong nicotine pouches.
2. Reduced endurance efficiency
Blood vessel constriction can slightly reduce oxygen delivery to working muscles — not ideal for steady-state or long-distance runs.
3. Nausea or dizziness
Using nicotine too close to a run — particularly higher strengths — can cause light-headedness or nausea, especially for newer users.
Timing matters more than strength alone
Before a run
Most runners report this as the worst time to use nicotine. Heart rate spikes and discomfort are common.
During a run
Generally avoided. Movement + nicotine absorption can feel unpleasant.
After a run
This is where most runners prefer nicotine use, as it avoids interfering with cardiovascular performance.
Runner tip: Keep nicotine and training separate. Stack them together and performance usually suffers.
Does pouch strength make a difference?
Yes — a big one.
High-strength products from brands like Killa or Pablo are far more likely to raise heart rate and impact endurance.
Runners who use nicotine tend to experience fewer issues with lower or mid-strength pouches, especially when used well away from training sessions.
Nicotine pouches vs smoking (important distinction)
Compared to cigarettes, nicotine pouches are significantly less damaging for runners.
Smoking affects lung capacity, oxygen uptake, and recovery — all critical for endurance performance.
Many runners who switch from smoking to nicotine pouches report improved breathing and stamina, even if nicotine itself still has cardiovascular effects.
If you’re transitioning, options like Nordic Spirit or other milder brands can feel more manageable.
What about recovery and sleep?
Nicotine can interfere with recovery by:
- Reducing blood flow slightly
- Suppressing appetite (affecting refuelling)
- Disrupting sleep if used late
Late-evening use — especially strong pouches — is one of the most common reasons runners report poor sleep quality.
So… should runners use nicotine pouches?
- Nicotine can raise heart rate and reduce endurance efficiency
- High-strength pouches have the biggest impact
- Timing matters more than many realise
- Post-run use tends to be least disruptive
Bottom line: Nicotine won’t instantly ruin your running — but it’s not helping your cardiovascular system either.
Final thoughts
If running performance matters to you, nicotine is something to manage carefully.
Keep strength sensible, timing separate from training, and pay attention to how your body responds.
