I ride a bicycle daily and vape e-cigs. If anything I notice an increased performance immediately after vaping, I feel like I'm less tired and have more energy.

Overall this is an interesting topic because contrary to popular opinion many athletes use nicotine and find that it increases their performance: Nicotine [...] use is widespread amongst professional team/strength sports (e.g. American football, ice hockey, wrestling, bobsleigh, gymnastics, rugby, skiing) whereby active consumption of nicotine and nicotine-containing substances in-competition occurs in approximately 25–50% of such athletes [1].

The meta-analysis [1] found that two studies observed an ergogenic effect, one an ergolytic with the remaining seven reporting no change.

Yeah, I never said I quit nicotine. Just switched to mostly gum.

It seems as if you were trying to maximize your performance, you'll ingest nicotine in a way that doesn't go through your lungs.

I cycle daily and vape. I feel when I vape more, my performance on a bicycle deteriorates very noticeably. My effective lung volume is noticeably lower.

Those athletes have trained for years and have a heart that is well conditioned with strength and cardio. A normal person who is moderately physically active is nowhere near their fitness level. That’s why nicotine is a dangerous thing to gamble with. You might be fine, or you might have afib/vfib that leads to an MI. Rather avoid the risk. Plenty of more potent PEDs out there that don’t cause adverse cardiac events.
