IQOS Heated Tobacco vs Vaping: What's Actually Different?

"Heated tobacco" and "vaping" get lumped together a lot — both are smoke-free, both involve a battery-powered device, and both are marketed to adult smokers as alternatives to cigarettes. But they're genuinely different products, built around different materials and different experiences. If you're trying to work out which one actually suits you, here's what separates them.

How heated tobacco (like IQOS) works

Heated tobacco devices use real tobacco. A small stick or capsule of processed tobacco leaf is inserted into the device, which heats it to a controlled temperature — hot enough to release nicotine and tobacco flavour compounds, but well below the point of combustion. Because there's no burning involved, there's no ash and no smoke in the traditional sense, just an aerosol. The stick is used once per session and then discarded, similar in ritual to smoking a cigarette: you get a fixed number of draws before it's done.

How vaping works

Vaping devices don't use tobacco leaf at all. Instead, a coil heats e-liquid — a mix of propylene glycol, vegetable glycerin, nicotine (or no nicotine, if you choose), and flavouring — turning it into an inhalable vapour. There's no combustion and no plant material involved. Depending on the device, you can vape continuously rather than working through a fixed stick, and the e-liquid itself can be swapped for a completely different flavour or nicotine strength whenever you like.

Where the two actually differ in practice

The mechanism difference cascades into a few practical ones that matter more day to day:

Flavour range: heated tobacco sticks are built around tobacco-forward flavour profiles, with a limited number of variants available at any time. Vaping e-liquid comes in an enormous range of flavours, from tobacco and menthol through to fruit, dessert, and drink-inspired blends — and switching flavours is as simple as changing what's in the pod or tank.
Customisation: vape devices let you adjust nicotine strength (commonly anywhere from 0mg up to 50mg in the pod systems we stock), and higher-end setups let you tune wattage and airflow too. Heated tobacco sticks come pre-set — the nicotine delivery and intensity are fixed by the manufacturer, so there's less to tweak.
Ongoing cost and consumables: heated tobacco runs on individual sticks, purchased similarly to a pack of cigarettes, used once each. Vaping runs on e-liquid bottles and replaceable coils or pods, which generally cover far more sessions per dollar spent, though this varies a lot by device and habits.
The physical ritual: if part of what you miss about smoking is the tobacco taste and the fixed "one stick, then it's done" rhythm, heated tobacco is deliberately built to mimic that. If you'd rather not think about topping up a fixed stick supply and want more control over flavour and strength, vaping is the more flexible format.

Nicotine delivery: similar goal, different feel

Both formats are designed to deliver nicotine without the combustion and tar produced by burning a cigarette, and both are aimed squarely at existing smokers rather than people who've never smoked. But the actual sensation differs — heated tobacco tends to feel closer to a cigarette in terms of throat hit and tobacco taste, since it's genuinely drawing on tobacco leaf. Vaping, particularly with nicotine salts, is formulated to deliver a smooth, fast-absorbing hit without needing tobacco at all, which is part of why it's become the more common switching option among pod-vape users.

Which one is worth trying?

There's no universal answer — it comes down to what you're looking for as a former or current smoker. If the tobacco flavour and the fixed stick ritual are what you'd miss most, heated tobacco is built to replicate that closely. If you want a wider flavour selection, the ability to dial in your own nicotine strength, and a device you can keep refilling rather than restocking, vaping is the more adaptable route. As a vape specialist, NZ Vapez stocks the device and e-liquid side of things rather than heated tobacco sticks, so if flexibility and flavour variety are what matter to you, our Vaping Devices range and Nicotine Salts range are the place to start. Many former smokers find a pod system with a tobacco or menthol nic salt gives a familiar-enough hit while still opening up the rest of the flavour range if they want to explore it.
