How do vapes and pod devices produce their aerosol?
A pod device uses its battery to power a coil or heating assembly inside the pod, turning the liquid into an aerosol. The liquid may contain nicotine, flavourings and carrier substances, but as a rule there is no tobacco leaf in the heating chamber, which separates it from heated tobacco at the level of material. Terms such as disposable, closed pod or open system describe how the device is refilled or the pod replaced; they have nothing to do with HEETS or TEREA.
In Thai, one word is used loosely for both pod cartridges and IQOS sticks, which is a major reason people assume the two are the same kind of thing when they are not.
Heated sticks are described on what TEREA is and HEETS versus TEREA.
What does IQOS do differently from a vape?
IQOS heats processed tobacco leaf held inside a dedicated stick. Blade models push a blade into a HEETS stick; ILUMA models use induction to warm an element inside a TEREA stick. There is no liquid tank and no pod to refill, so in mechanical terms IQOS is a heated tobacco product, not an e-cigarette. The WHO distinguishes the two groups in exactly this way: heated tobacco heats tobacco, and an e-cigarette heats a liquid.
Calling IQOS an e-cigarette in conversation is understandable, but content should state the difference so that readers open the right guide.
The induction system is explained on ILUMA i; the blade system on IQOS 3 DUO; sticks by market on TEREA Japan.
Can pods, e-liquid, HEETS and TEREA be interchanged?
No. A pod is a cartridge or tank for liquid, HEETS is a tobacco stick for blade-family IQOS, and TEREA is a tobacco stick for ILUMA. The three differ in size, contact points and heating method, and no standard adapter exists that lets them cross systems safely. Any product claiming cross-system use should be checked against the manufacturer's manual and the full model name first. This site does not recommend modifying devices, since that can affect the battery, the heating chamber and ventilation.
Modification advice found in videos rarely comes with any manufacturer backing, and following it can void whatever support the maker offers.
The full stick-to-device pairing is on stick types, with SENTIA as a further ILUMA line and current models on latest IQOS models.
Why do vapes and IQOS look so alike?
Both are portable, battery-powered, carry status lights and need charging, so they end up in similar stick or box shapes. The parts inside serve different material: a pod device houses a liquid pod and a coil, while an IQOS houses a holder or an induction chamber for a tobacco stick. Looking at the outside is not enough. Check whether there is a liquid filling port, a removable pod, or a slot for a tobacco stick, and read the model name printed on the device.
Our latest-devices page shows the shape of each IQOS family to help with that visual check, from one-piece models to holder-and-charger pairs with a separate case.
See the device comparison and the devices section; pack sizes for sticks are on the TEREA hub.
Is charging a vape the same as charging an IQOS?
Some models share a USB-C port, but power specifications, charging cycles and status lights differ. A two-piece IQOS with a holder and pocket charger charges in two stages, while many pod devices charge the unit directly or are disposable. A matching plug does not mean every adapter is suitable; read the model's manual and the rating printed on the charger. Our charging guidance covers IQOS status lights only, and pod devices should follow their own manufacturer's instructions.
Treating the two as the same because the cable fits is a common and avoidable mistake that the manuals warn against.
IQOS charging steps are on how to use IQOS; premium models with a separate holder are covered on latest IQOS models and ILUMA i.
How does cleaning a vape differ from cleaning an IQOS?
Pod devices mostly need contacts wiped and leaked liquid dealt with. Blade-family IQOS models need care around tobacco residue and the blade, while ILUMA has no blade and is not cleaned the way the older models are. Using a brush or liquid in the wrong place can break a device. Every cleaning guide should therefore begin by identifying the device type: a pod video should not be applied to an IQOS, and blade-model steps should not be applied to an ILUMA.
Our cleaning material keeps the two IQOS families in separate tables for that reason, and pod devices are left to their own makers.
Start at how to use IQOS; the blade model is on IQOS 3 DUO. For cigarette-related search terms, see Marlboro types.
How does the WHO describe vapes and heated tobacco?
The WHO states that e-cigarettes turn a liquid into an aerosol and are not safe, and that heated tobacco products are tobacco products producing an aerosol with nicotine and toxic substances. It does not accept the reading that the absence of combustion means the absence of risk. This site accordingly avoids words like healthy or safe without an evidence framework and has no commercial pages. People who do not use tobacco or nicotine should not start; the products discussed are for adult information only.
Public health guidance, not this site, is the place for any conclusion about risk of any kind.
The mechanism-only comparison continues on cigarettes compared with heated tobacco, with other heated systems on IQOS vs glo vs Ploom and bridge context on Japanese cigarettes and IQOS.
Does Thai law treat vapes and IQOS the same way?
In practice, yes. Although the mechanisms differ, Thailand's import and distribution bans cover both e-cigarettes and heated tobacco products, and official UK travel advice describes heat-not-burn devices as illegal to possess or use there. Anyone searching for a vape or IQOS outlet in Thailand should receive a legal answer, not a list of vendors. Availability abroad or online does not make import into Thailand lawful, so the latest official notices should be read before travelling.
The details of the relevant notices and announcements are set out on our Thai legal pages, which are updated whenever the official sources change or new notices appear in Thailand.
