When you quit vaping, you're dealing with two problems at once: your body wants nicotine, and your hands and brain want the habit. Nicotine replacement therapy (NRT) tackles the first problem so you have more energy to deal with the second.
NRT means products like nicotine patches, gum, and lozenges. They give you a controlled amount of nicotine without the vape, which takes the edge off withdrawal while you break the routine. Then you step down over time until you don't need them. Here's how it works, what the research says, and what to ask before you start.
How nicotine replacement therapy works
When you stop vaping suddenly, your nicotine level drops and your brain notices. That drop is what drives the cravings and discomfort of nicotine withdrawal.
NRT softens that drop. According to the FDA, it works by giving your body smaller doses of nicotine over time, without the toxic chemicals in tobacco smoke. Smokefree.gov explains that this small, controlled amount of nicotine helps satisfy cravings and reduces the urge to use.
The key difference from vaping: NRT delivers nicotine more slowly and steadily. You don't get the quick hit, and you're not inhaling anything into your lungs.
Types of NRT
There are five types of NRT. Three are sold over the counter to adults, and two need a prescription.
| Type | How you get it | How it works | Speed |
|---|---|---|---|
| Patch | Over the counter, 18+ | Sticks to your skin and releases a steady amount of nicotine | Long-acting |
| Gum | Over the counter, 18+ | You chew until it tingles, then "park" it between your cheek and gum | Fast-acting |
| Lozenge | Over the counter, 18+ | Dissolves slowly in your mouth (don't chew or swallow it) | Fast-acting |
| Inhaler | Prescription | A cartridge on a mouthpiece that releases nicotine when you puff | Fast-acting |
| Nasal spray | Prescription | A pump spray into the nose | Fast-acting |
A Cochrane review found that, in smokers, the different forms worked similarly well, so the best one is often the one you'll actually use. Gum and lozenges give you something to do when a craving hits. Patches are easy because you put one on and forget about it.
Does NRT work? What the research says
Here's the honest picture: the evidence for NRT is very strong for quitting smoking, and still thin for quitting vaping.
For smoking, the evidence is excellent. A 2018 Cochrane review of 133 trials with more than 64,000 people found that every licensed form of NRT increased quit rates by about 50% to 60% compared with placebo or no NRT. It worked with or without extra counseling, and the reviewers rated the evidence high-quality.
For vaping, we don't know as much yet. A 2025 Cochrane review of treatments for quitting vaping found that the data on combination NRT were inconclusive, mostly because there are only a few small studies so far. That doesn't mean NRT doesn't work for vaping. It means researchers haven't finished testing it.
So when experts recommend NRT for vaping, they're applying what works for smoking to a similar nicotine addiction. That's reasonable, but it's worth knowing. The same Cochrane smoking review also noted there's little evidence on NRT for very light smokers, which may matter if you only vape occasionally.
Why combination NRT works better
If you use NRT, consider asking about combination NRT: a long-acting patch plus a fast-acting form like gum or a lozenge.
- The patch keeps a steady baseline of nicotine all day, so withdrawal doesn't spike.
- The gum or lozenge handles breakthrough cravings, like after a meal or during stress.
A 2023 Cochrane review found that, in people quitting smoking, using a patch together with another type of NRT made them 17% to 37% more likely to quit than using one type alone. The American Academy of Pediatrics also recommends pairing a long-acting form with a short-acting one for best results.
If you're under 18
This part matters. Over-the-counter NRT is approved for people 18 and older, and the FDA says anyone under 18 should speak to a doctor before using quit products.
That doesn't mean teens are out of options. The American Academy of Pediatrics says:
- The FDA hasn't approved NRT for people under 18, and research on how well it works in teens is limited and mixed.
- There's no evidence of serious harm from NRT in teens.
- Doctors may consider prescribing NRT off-label for teens who are moderately or severely addicted to nicotine and motivated to quit.
- Teens need a prescription to get any form of NRT.
So if you're a teen and withdrawal feels like too much, talk to your doctor, school nurse, or a quitline coach. Free teen programs are listed in our guide to free help to quit vaping.
Questions to ask a pharmacist or doctor
We're not going to tell you what dose to take, and you shouldn't take dosing advice from a website. Vapes vary a lot in how much nicotine they deliver, and the AAP notes that nicotine salt vapes can deliver much higher levels than older products. A pharmacist can help you match NRT to how much you actually vape. Bring these questions:
- What strength should I start with, given what I vape and how often?
- Should I use combination NRT (patch plus gum or lozenge)?
- How long should I use it, and how do I step down?
- Is it safe with my health conditions or medications? The FDA says your provider may consider things like pregnancy, heart disease, diabetes, depression, asthma, and blood pressure.
- Am I using it correctly? Gum works differently from regular gum, and lozenges shouldn't be chewed.
Always follow the product label. Common side effects depend on the type: patches can irritate your skin or disturb sleep, and gum and lozenges can irritate your mouth. Cochrane found no evidence that NRT increases the risk of heart attacks.
Other prescription options exist too, like varenicline and bupropion. The 2025 Cochrane vaping review found low-certainty evidence that varenicline may help people quit vaping. Ask your doctor whether those fit you.
NRT works best with support
NRT handles the nicotine, but it can't do all the work. Smokefree.gov notes it won't completely take away the urge, and recommends combining it with a quitline or text program. Pair it with:
- A plan for cravings and triggers. See how to stop vape cravings.
- A way to track progress. The free Escape the Vape app tracks your streak, money saved, and health recovery, and has a community of people quitting with you.
- Something for your hands and breath. NRT won't replace the hand-to-mouth ritual. Some people use a breathing tool like The Escape Necklace, a nicotine-free stainless steel mouthpiece you exhale slowly through when a craving hits.
- A quitline call. Some state quitlines give eligible adults free patches, gum, or lozenges.

You don't get extra points for suffering
Using NRT isn't cheating. It's a tested tool that makes withdrawal more manageable, so you can focus on building a life that doesn't revolve around your vape. If you're 18 or older, talk to a pharmacist today. If you're younger, talk to a doctor. Either way, you don't have to white-knuckle this.
