Nicotine is a widely used stimulant and potent parasympathomimetic alkaloid that is naturally produced in the nightshade family of plants (most notably in tobacco, in particular). It is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist.Wikipedia
Nicotine Free is highly effective thanks to its natural ingredients. The food supplement contains, e.g., chicory, African mango, glucomannan, chromium, or green tea. This combination creates an effective formula that helps quit smoking.
