What this is
Heishman 2010 meta confirmed cognitive benefits on attention, episodic/working memory in non-smokers at low doses. Addiction is the core problem — reports of 'I'll only use occasionally' are notoriously unreliable. Non-combustible forms avoid combustion toxicity but not addiction/CV risk. Absolutely avoid in pregnancy.
Mechanism
Non-selective nAChR agonist; stimulates α4β2 and α7 receptors; modulates dopamine, glutamate, GABA; acute attention/working memory enhancer in many paradigms
Dose & route
Lozenge/gum/patch 2-4 mg; cognitive use typically 1-2 mg acute
