What is the main difference between a cigarette and heated tobacco?
Combustion. A cigarette is lit with a flame and its tip burns continuously. A heated tobacco product uses a temperature-controlled device to warm tobacco without a flame. The WHO explains that these products produce an aerosol containing nicotine and other chemicals. The phrase no combustion should never be read as no risk: the WHO states that heated tobacco products are tobacco products and contain some toxic substances. This comparison stays with structure, device and operation.
Everything on this page is about how the two products work, not about health outcomes, which we leave to public health bodies such as the WHO and national regulators.
The heating side is introduced on heat-not-burn explained and the stick side on what TEREA is.
Does a conventional cigarette need any device or battery?
No. A cigarette consists of tobacco, paper and a filter, and is lit at the tip; its energy comes from continuous burning. A heated tobacco product needs a battery, a temperature controller and a heating chamber or holder, so it must be charged and maintained. This changes the kinds of problems a user meets: a cigarette has no status lights or charging port, while a device may have a low battery, a poor contact or the wrong stick inserted.
Charging and troubleshooting guides therefore belong to devices, and have no equivalent for cigarettes, which simply need a flame and nothing more to function at all.
Device-specific guidance is on how to use IQOS, with market stick lists on TEREA Japan and TEREA Pearl.
Do heated tobacco sticks resemble cigarettes?
From the outside they can look like a short cigarette, but the inside is purpose-built: a tobacco section, a filter, air channels and, in some systems, a heating element, as in TEREA for ILUMA. HEETS are shaped so that the blade of an older model can enter them. Neither should be lit or used as a cigarette, and a conventional cigarette should never go into a holder. Similar shape is no proof of compatibility; the stick and device names in the manual are.
The manual for the exact model is the only reliable reference for which stick goes where, and it takes precedence over any video.
Structure by stick family is explained on stick types, with SENTIA on its own page and current models on latest IQOS models.
Is cigarette smoke the same as heated tobacco aerosol?
Not in how it is produced. Cigarette smoke comes from combustion; a heated tobacco product generates an aerosol by warming the tobacco. Both nevertheless contain nicotine and many chemicals, and the WHO cautions that lower levels of certain substances do not automatically mean lower health risk. Smokeless should therefore be understood as no combustion smoke, not as nothing being released. Use indoors still depends on the law and the rules of the venue; heated products are not usable everywhere.
Venue rules and national law decide where any tobacco product may be used, whatever the mechanism, and a device gives no special permission indoors or in a vehicle carrying other people.
Device details are on IQOS 3 DUO and ILUMA i; pack information is on the TEREA hub.
Do both cigarettes and heated tobacco contain nicotine?
Yes. Both use tobacco and deliver nicotine, which the WHO identifies as addictive. Changing the product format does not remove it. Information sites should display an adults-only warning and avoid presenting either product as a toy or an ordinary lifestyle accessory. Anyone wishing to stop using tobacco should consult a health professional and use evidence-based methods; a comparison of mechanisms is not a basis for treating heated tobacco as a cessation tool.
The WHO position is that heated tobacco products should not be claimed to help end tobacco use.
Flagship devices such as those on the devices section carry the same nicotine caveat as every other product discussed here; the nicotine question for sticks is answered on HEETS versus TEREA.
Can heated tobacco sticks be swapped between brands?
No. Each device family uses its own system and dimensions. HEETS work with blade-family IQOS, TEREA with ILUMA, and Ploom and glo have their own sticks. Inserting the wrong stick may mean the device does not start, becomes dirty, or is damaged. Before choosing accessories or sticks, check the full model name and the country of the manual. A brand comparison helps identify the family, but the final word is the manufacturer's manual for that model.
Cross-brand adapters are not something the manufacturers describe, and this site does not suggest modifications of any device.
Families are compared on IQOS vs glo vs Ploom and models on the device comparison; a related cigarette question is on Marlboro, IQOS and TEREA.
Are cigarettes and heated tobacco regulated the same way everywhere?
No. Countries may permit, regulate or ban heated tobacco differently from cigarettes, even though the WHO classes both as tobacco products. Availability in one country is never evidence that import into another is allowed. Thailand prohibits the import and distribution of this product group, and official travel advice states that heat-not-burn devices are illegal to possess or use there. Travellers should check destination law, airline rules and battery requirements together.
Possession, import and in-flight carriage are three separate questions, which our legal section keeps apart so that an answer to one is not mistaken for an answer to all three.

Which page comes first when learning about heated tobacco?
Begin with the heat-not-burn page to understand the product category, then read what IQOS is to see how that one system works, and only then move to model comparisons and stick types. Going from category to device to stick causes far less confusion than starting with flavour names. If the original search was for a cigarette brand, that brand's question deserves a straight answer first, followed by an honest note on how it differs from heated tobacco.
A bridge page should never turn every cigarette search into a device pitch or imply that the products are interchangeable in any way, because they plainly are not, whatever the search term.
The recommended path: heat-not-burn, then what IQOS is, then the full guide index.
