Can nicotine improve focus?

Yes, nicotine can improve focus. Andrew Huberman explains that nicotine triggers the release of norepinephrine and activates neurochemical pathways that increase alertness, energy, and arousal. This makes people feel focused and decreases sleepiness 1 . Moreover, nicotine increases acetylcholine, which enhances attention and concentration, although these effects are short-lived, lasting about 30 to 45 minutes 2 .
