This page collects what is actually established, with the size of the effect where it is known and the gaps stated plainly.

The borrowing problem

Vaping cessation is a young field. Most of what we know comes from decades of smoking-cessation research, applied on the reasonable assumption that nicotine dependence is nicotine dependence.

That assumption is broadly sound, but it has limits: vaping is often higher-dose, cue patterns are different (indoors, all day, no smell), and users are younger. Read the numbers below as directionally reliable rather than precise for vaping.

Nicotine replacement therapy

The strongest single evidence in the field.

  • Cochrane's review of NRT in smokers finds it increases the chance of quitting by roughly 50–60% relative to placebo.
  • Combination NRT, a patch for baseline plus gum, lozenge, or spray for breakthrough cravings, outperforms a single product.
  • It is under-used and typically under-dosed. Most people who fail on NRT used too little of it for too short a time.

For vaping, work out your daily nicotine intake in mg first; that determines the patch strength that makes sense.

Behavioural support

Independent of medication, structured behavioural support increases quit rates. The active components are unremarkable:

  • Setting a quit date
  • Identifying triggers in advance
  • Planning specific responses
  • Repeated contact over weeks, not one session

Quitlines deliver this free in most countries and are consistently under-used.

Digital programs

  • Cochrane finds text-message programs increase quit rates in smokers.
  • App evidence is weaker and much more variable, the category includes both tested programs and untested products.
  • This is Quitting, built specifically for vaping, was evaluated in a randomised trial and increased abstinence among young adults.

Reasonable read: digital tools add a modest, real increment, and work best alongside NRT rather than instead of it.

Prescription medication

Varenicline and bupropion have strong evidence in smoking cessation. Emerging trials support varenicline for vaping cessation in young adults. Both are prescription-only, and suitability is a clinician's call.

Tapering versus cold turkey

The evidence here is genuinely mixed. Abrupt cessation performs at least as well as gradual reduction in most smoking trials, but tapering with NRT support is a reasonable option for very heavy users and for people who have failed abruptly before. Preference matters, because adherence matters more than the method.

What has weak or no evidence

  • Hypnotherapy: inconsistent, low-quality evidence
  • Acupuncture: no reliable effect over placebo
  • Switching to lower-nicotine liquid without a schedule: usually results in compensatory puffing
  • "Willpower alone": the most common approach, and the least effective

The practical summary

If you want to maximise odds using what is actually evidenced:

  1. Work out your daily nicotine in mg.
  2. Use combination NRT at an adequate dose, for at least eight weeks.
  3. Add structured support, a quitline, a program, or an app you will genuinely open.
  4. Plan for your top three triggers before quit day.
