Vaping is becoming increasingly popular among athletes as a more discreet and lower health-risk alternative to smoking, as some studies have found that smoking can have a negative impact on physical performance. Vaping delivers nicotine and other chemicals without many of the thousands of toxins that cigarettes produce, allowing athletes to reap the benefits of nicotine without the long-term health risks. Research indicates some nicotine might help with reduced fatigue and sharper focus while using vaping prior to exercise has been associated with greater self-reported exertion and blood flow. The verdict is still out, though, so more research needs to be done.
