Yes, NRT is safe and effective - in fact, the risks and side effects of consuming NRT are very similar to those of caffeine. NRT does not contain the dangerous chemicals that are present in vapes or tobacco.
Doctors and other medical experts (including the CDC & smokefree.gov) recommend NRT as one of the most helpful tools you can use to quit. It’s been FDA-approved and heavily studied for over 30 years (the first NRT was used in 1967!), and the research shows that NRT is safe and effective for almost all adults looking to quit. NRT has been approved for over-the-counter use since 1996.
Most adults (anyone 18+) can take NRT without consulting a doctor. There are very few people who shouldn’t use NRT. Pregnant women, teens, and people with serious health issues (like heart or lung disease) still might be able to use NRT, but should talk to their doctor first. Some people are allergic to the compounds in NRT that don’t include nicotine but those people are very, very rare. If you have known sensitivities, we advise you to read the ingredients before taking NRT. People allergic to Soya products should not use nicotine lozenges.
