Is the IVG Pro 12 worth it for ex-smokers?

The IVG Pro 12 is sold and marketed as a "disposable alternative" rather than as a smoking-cessation product, but the realistic customer for this device is overwhelmingly someone who used to smoke cigarettes, not someone switching from another vape kit. That distinction matters when you're working out whether to spend £10.95 on this specific device versus a hundred other options on the market. A pod kit that suits an ex-smoker has slightly different requirements than one that suits a recreational vaper: throat hit needs to mimic a cigarette draw, nicotine delivery has to satisfy actual cravings rather than just produce vapour, the form factor needs to feel ritualistic enough to replace the cigarette habit. The Pro 12 ticks all three boxes, but it's not the only device that does, and it's not the right pick for everyone.

This page covers four things. The NHS evidence on vaping as a stop-smoking tool, with the actual numbers and citations rather than vague claims. Cost savings over 30, 90, and 365 days compared to a 20-a-day cigarette habit, with the realistic delta worked out. Honest "yes if" and "no if" reasons for picking this device versus an alternative, including who should genuinely look elsewhere. And the practical considerations for ex-smokers in their first month of switching: nicotine strength, throat hit expectations, and what to do when cravings hit.

Important caveat upfront: vaping is not risk-free, and the long-term healthiest position is to use neither cigarettes nor a vape. The aim of recommending the Pro 12 (or any vape) to an ex-smoker is to replace the more harmful habit with the less harmful one, not to introduce a new lifelong dependency. Tapering down nicotine strength over time is something we cover in a later page in this guide; it's worth knowing that's the eventual aim.

The framing the NHS uses

The NHS position on vaping as a smoking-cessation tool is unambiguous: it works, it works better than other nicotine-replacement options, and it's officially recommended for adult smokers trying to quit. The "twice as likely to quit" figure isn't marketing; it comes from a 2021 Cochrane Review (the gold-standard for medical evidence in the UK), and is published prominently on the NHS Live Well page about quitting smoking. A 2021 review found people who used e-cigarettes to quit smoking, as well as having expert face-to-face support, can be up to twice as likely to succeed as people who used other nicotine replacement products, such as patches or gum.

The 95% figure is older but still widely cited. It originates with the Office for Health Improvement and Disparities (OHID), which states that vaping is around 95% less harmful than smoking because it does not produce toxic tobacco smoke or dangerous carbon monoxide. The framing is "less harmful", not "harmless"; vaping carries some risk and the long-term effects are still being studied, but the comparison to smoking is dramatic. The risk profile shifts substantially when you're swapping out the burning-tobacco part of the equation.

The two-thirds quit success rate from the NHS Better Health page comes specifically from data on people who use a vape alongside support from a local Stop Smoking Service. The "alongside support" qualifier is doing real work: vapes alone perform less well than vapes combined with structured behavioural support. If you're serious about quitting, the right framing is "use a vape and use the NHS service together" rather than picking one or the other.

"The Pro 12 is one tool in a quit-smoking strategy, not the strategy itself. The customers we see making the cleanest transitions are the ones combining the device with NHS Stop Smoking Service support, not just walking out with the kit and hoping."

Why the Pro 12 specifically

If vapes-in-general are an effective stop-smoking tool, why recommend the Pro 12 over the dozens of alternatives? Three reasons. The 20mg nicotine salt formulation is calibrated to deliver a satisfying nicotine hit similar in absorption profile to a cigarette; salt nicotine acts faster than freebase, hitting the bloodstream within minutes rather than building gradually. The cigarette draw produces nicotine peak around 10 minutes after the first inhale; salt nicotine vape produces a similar curve. Most ex-smokers find this is what makes a vape "feel like" a satisfying replacement rather than a frustrating substitute.

Second, the MTL inhale matches what cigarette smokers expect. The Pro 12's tight, fixed MTL airflow draws like a cigarette: pull a small amount of vapour into the mouth, then breathe it down. Sub-ohm devices and direct-lung kits don't replicate this technique and feel alien to people coming from cigarettes. We cover this in detail in our airflow guide; the short version is the Pro 12 is correctly tuned for the cigarette-replacement use case.

Third, the prefilled-pod format removes a barrier to switching. Ex-smokers who walk out with a refillable kit that needs bottled e-liquid often abandon it within a week because the maintenance feels like a hobby they didn't want. The Pro 12 doesn't ask them to learn anything: click the pod in, inhale, charge when needed. That's genuinely the entire interaction, and it's why we recommend it as a transition device rather than as the long-term endpoint.
