Smokers generally cannot hold their breath as long as non-smokers. Studies show a significant reduction in breath-holding time (BHT) among smokers.
Breath-Holding Time in Smokers vs. Non-Smokers
One study found that the average breath-holding time for smokers was 34.85 seconds, compared to 46.61 seconds for non-smokers. This difference was statistically significant, indicating that smoking negatively impacts lung capacity and breath-holding ability. [Source: Study showing mean BHT difference between smokers and non-smokers].
Other research supports this finding. Many sources suggest that most healthy adults, excluding heavy smokers and those with conditions like COPD or CHF, can hold their breath for around 38 seconds in a single breath hold, or up to six 12-second breath holds.

Factors Affecting Breath-Holding Time
Several factors besides smoking influence how long someone can hold their breath:
- Underlying health conditions: Lung diseases like COPD significantly reduce BHT.
- Breath training: Practice and techniques can improve breath-holding time.
- Motivation: Mental fortitude affects how long someone pushes their limits.
- Age and fitness level: Physical fitness correlates with improved lung capacity.
It is important to note that while some smokers may have a surprisingly long BHT due to increased tolerance to high CO2 levels, this does not negate the overall negative impact of smoking on lung health and respiratory function.

Conclusion
While individual results vary, smokers typically have a significantly shorter breath-holding time compared to non-smokers due to the damaging effects of smoking on lung function.
