I. Source and Existence Form
Nicotine salts are the natural state of nicotine found in tobacco leaves and also exist in tobacco products such as cigarettes, cigars, and waterpipes. In e-cigarettes, nicotine salts are often used as a main ingredient to imitate the throat hit and absorption rate of tobacco while avoiding the tar and carcinogens associated with traditional smoking.
II. Physical and Chemical Properties
Compared to nicotine in other e-liquid forms, such as free-base nicotine, nicotine salts have higher nicotine strength and faster absorption rates. Nicotine salts are in their natural state, making them more stable, with a longer shelf life, and less prone to nicotine degradation.
III. Effects and Impacts
When nicotine salts bind to nicotinic receptors in the adrenal medulla, they increase the level of adrenaline in the blood, leading to physiological responses such as accelerated heartbeat, increased blood pressure, and faster breathing. Nicotine salts also have a role in aiding smoking cessation by alleviating anxiety and irritability during withdrawal and reducing symptoms caused by suddenly stopping smoking. However, it should be noted that the use of nicotine salts may have cardiovascular side effects and should be done under medical supervision.
IV. Manufacture and Common Acids
In the process of manufacturing nicotine salts, lactic acid, benzoic acid, and acetylpropionic acid are the most common acids used. Among them, benzoic acid is the most frequently used acid for manufacturing nicotine salts.
In summary, nicotine salts are widely present in tobacco products and e-cigarettes, possessing specific physical and chemical properties, effects, and impacts. When using products containing nicotine salts, it is important to fully understand their properties and potential risks and to do so under medical guidance.
