Nicotine hydrochloride liquid or solution


Nicotine is an alkaloid found primarily in plants of the nightshade family, notably in tobacco; it is also synthesized. Nicotine is used recreationally for its stimulant and anxiolytic effects. In tobacco leaves, nicotine constitutes about 0.6–3.0% of the dry weight, and smaller, trace quantities occur in other Solanaceae crops such as tomatoes, potatoes, and eggplants. In pure form, nicotine is a colorless to yellowish, oily liquid that readily penetrates biological membranes and acts as a potent neurotoxin in insects, where it serves as an antiherbivore toxin Wikipedia
