A smoker can get a Scopolamine injection to help him stopping smoking, according to Stop Smoking Foundation. The injection works by inhibiting the nicotine receptors, which are the main part of the brain involved in addictions.
A Scopolamine injection helps to clear from the sensory memory the "sweet" feeling nicotine provides, explains Stop Smoking Foundation. As a result, this suppresses the individual's urge to smoke. A smoker must first receive a medical testing prior to getting a smoking injection, and the injection has several side effects, including dry mouth, dizziness, blurry vision, difficulty urinating and confusion. It may also cause serious side effects, such as hallucinations, delirium and temporary blindness.
