Nicotine delivery refers to the methods used to introduce nicotine into the body. This can occur through various products, including traditional cigarettes, e-cigarettes, and nicotine replacement therapies like patches and gums. Each method affects how quickly and efficiently nicotine enters the bloodstream, influencing the user's experience and potential addiction. The efficiency of nicotine delivery can vary significantly. For instance, smoking a cigarette provides rapid absorption, leading to quick effects, while patches release nicotine slowly over time. Understanding these differences is important for individuals seeking to manage their nicotine intake or quit smoking altogether.
