The Nicotrol inhaler and e-cigarettes, such as Blu eCigs or NJOY, are designed to help smokers quit. They work by delivering a nicotine vapor into the lungs as a person inhales. A smoker can use these products to wean himself off nicotine.
Cigarettes contain nicotine as well as other harmful ingredients, such as tar. The use of an inhaler or e-cigarette allows a smoker to reduce contact with those other substances while satisfying his craving for nicotine. In a study published by the National Institutes of Health, researchers found that e-cigarettes had higher satisfaction ratings than the Nicotrol device. Additionally, e-cigarettes do not require a prescription but Nicotrol does.
