Can nicotine replacement therapy (NRT) help people quit smoking?

Background

We reviewed evidence about whether NRT helps those who want to quit smoking for six months or longer to stop smoking. NRT aims to reduce symptoms associated with smoking by presenting nicotine withdrawal from cigarettes. NRT is available for skin patches that deliver nicotinea lentils, and gum, nose, and oral sprays, inhalers, and tablets/chewing tablets, all of which deliver nicotine to the brain faster than the cuticle, but less quickly than Spanish smoking.

Study the characters

This review includes 136 NRT exams, with 64,640 people in the main analysis. All studies were performed on people who wanted to quit smoking. Most studies were conducted on adults and had similar numbers of men and women. Men enrolled in the study were typically smoking cigarettes at least 15 days after the start of the study. The evidence is current until July 2017. The trial lasted at least six months.

Event key

We found that all forms of NRT evidence made it more likely that someone attempted to quit smoking. Chances of closing smoking increased by 50% to 60%. NRT works with or without additional advice and does not need to be prescribed by a doctor. Side effects from the use of NRT are related to the product type, and include skin irritation from patches and irritation to the inside of the mouth from gums and tablets. There is no evidence that NRT increases the risk of a heart attack.

The quality of the evidence

The overall quality of the content is high, meaning further research is very likely to change our conclusions.
