Nicotine
Nicotine is the principal alkaloid of tobacco. Beyond its association with smoking, pure nicotine has cognitive enhancement effects via nicotinic acetylcholine receptor agonism. Pouches and gums isolate the cognitive effects from the carcinogenic combustion products of cigarettes. Not stocked by Kodiac. This monograph is provided for research and educational reference.

Nicotinic acetylcholine receptor agonist
A pyridine alkaloid from tobacco (Nicotiana spp.) with broad nicotinic acetylcholine receptor agonist activity, studied at low doses for cognitive enhancement.
Abstract
Nicotine (CAS 54-11-5; molecular formula C10H14N2; molecular weight 162.23) is a pyridine alkaloid present principally in Nicotiana tabacum and other Solanaceae species. The compound is a potent agonist at nicotinic acetylcholine receptors (nAChRs) with affinity that varies by subunit composition: alpha4-beta2 nAChRs (high abundance in CNS) at high affinity, alpha7 nAChRs at moderate affinity, alpha3-containing autonomic nAChRs at moderate affinity. Low-dose nicotine has been studied extensively for cognitive enhancement (improved attention, working memory) in non-smokers; effect sizes are modest but consistent. Smoking cessation pharmacotherapy uses nicotine replacement (gum, patch, lozenge, inhaler, nasal spray) at doses sufficient to relieve withdrawal but lower than typical cigarette smoking exposure. The compound is highly addictive when delivered through rapid-onset routes (smoking, vaping); slower-onset routes (gum, patch) have lower abuse liability. Reported research dose ranges in the literature are described in the source publications.
Mechanism of action
Nicotinic acetylcholine receptor agonist with subunit-dependent affinity (alpha4-beta2 high, alpha7 moderate, autonomic moderate).
Reported research dose ranges
