Why and how do we breathe?
What is nicotine and how would one typically go about inhaling the product? Nicotine: A stimulant and potent parasympathomimetic alkaloid that is naturally produced in the nightshade family of plants. It is used for smoking cessation to relieve withdrawal symptoms. In the form of smoking: A cigarette is a narrow cylinder containing psychoactive material, typically tobacco, that is rolled into thin paper for smoking. A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. They are produced in a wide variety of sizes and shapes. Tobacco is a plant that contains nicotine, a psychoactive (mind altering) drug that speeds up activity in our central nervous system but has relaxing effects too. In the form of vaping: E-cigarettes: Handheld battery-powered vaporizers, that simulate tobacco smoking. Instead of cigarette smoke, the user inhales vapor, so using an e-cigarette is called "vaping". They typically have a heating element that atomizes a liquid solution called e-liquid.
