Tobacco Smoke Enemas
Tobacco smoke enemas were practiced in the 18th century to treat various ailments. Back in the day, this procedure was administrated to patients suffering from headaches, respiratory failure, cold, or abdominal cramps, just to name a few. This method was even used to resuscitate individuals who were dying from typhoid fever or cholera. It was believed that nicotine could stimulate a patient's adrenal glands, produce adrenaline, and revive them. Unsurprisingly, this method hardly ever worked.
