"Nicotine-free" refers to products or substances that do not contain nicotine, a highly addictive chemical found in tobacco. Many people seek nicotine-free options to reduce their dependence on tobacco or to avoid the harmful effects associated with nicotine consumption. These products can include herbal cigarettes, nicotine-free vaping liquids, and various smoking cessation aids. In recent years, the demand for nicotine-free alternatives has grown, particularly among those looking to quit smoking or reduce their nicotine intake. This shift has led to the development of a variety of herbal products and vaping options that provide a similar experience without the addictive properties of nicotine.
