The evidence in words
The verdict
For attention / working memory, Nicotine earns evidence grade B (small effect, high consistency) — there is real evidence here. Real but modest
How it might work
It agonizes nicotinic acetylcholine receptors, sharpening attention, working memory and reaction time — and driving powerful dopaminergic reward and dependence.
How to use it
Safety & cautions
Highly addictive; raises heart rate and blood pressure; toxic in overdose (especially liquids around children). Not for anyone nicotine-naïve, pregnant, or with cardiovascular disease.
Bottom line
A real attention enhancer with an unusually bad addiction and cardiovascular profile. If you don't already use nicotine, the cognitive benefit is not worth the dependence risk.
