Nicotine (non-combusted)

Evidence: ★★★☆☆ · Status: OTC Supplement, Controlled

💡 Did you know? Nicotine and smoking aren't the same thing — nicotine is a stimulant being studied for focus; it's the tar and combustion that kill.

In plain English

Genuinely sharpens focus and reaction time by hitting acetylcholine receptors — but it's strongly addictive, so the cognitive upside rarely outweighs the dependence risk. (Divorced from smoking's other harms, but still.)

How it works

Agonist at nicotinic acetylcholine receptors (CHRNA4, CHRNA7), enhancing attention, working memory, and reaction time; highly addictive via mesolimbic dopamine.

Molecular target & official sources
