Electronic cigarette: the clue is in the liquid
The WHO distinguishes electronic cigarettes, which heat a liquid to generate aerosol, from heated tobacco products, which heat tobacco. Its tobacco and nicotine fact sheet, updated in June 2026, presents the two categories separately. Sharing a battery does not make the material, emission or product identical.

Comparing them with other appliances helps: a coffee machine and an iron use electricity and heat, but those similarities do not define their complete function. Something similar happens here at the classification level. External appearance tells us very little unless we know which material is being described and which process the source examines.
Vaporiser: a word that needs context
In commercial and everyday language, vaporiser may appear as a broad name without precisely identifying the category. It is therefore useful to treat it as the beginning of a description. The next question is what the text means: an electronic cigarette containing liquid, a heated tobacco product or another device?
If a news story mentions solid plant material, transferring the definition of a liquid device is no longer enough. This does not classify the product on its own or determine its legality. It simply indicates that a description is missing. Nor does the word vaporiser establish that a device is compatible with any material or that all devices work equivalently.
Heated tobacco: the qualifier matters
WHO Europe has specifically warned about confusion between heated tobacco products and electronic nicotine delivery systems. The former contain tobacco; the latter, in the distinction explained by that source, heat a liquid. It also distinguishes systems declared to be nicotine-free. These categories require precision; they are not alternative names for one thing. WHO Europe: distinguishing electronic cigarettes and heated tobacco
One way to remember this is to create an imaginary record with three lines: material, mechanism and category. On the first, write what it actually contains; on the second, what the system does; on the third, its documented classification. If the first two are missing, the third risks becoming an assumption based on a photograph.
Different does not create an automatic safety ranking
The WHO fact sheet presents none of these categories as harmless. Distinguishing them helps us understand the evidence; it does not establish a contest in which the most technological name wins. A claim about one type of product should not be transferred to another without checking what was compared and which outcome was measured. WHO: tobacco and nicotine, June 2026
The context of a figure matters too. A study of an emission’s composition is not necessarily a study of long-term health outcomes. And a result obtained with a particular model does not describe every device sharing a commercial term. Precision prevents both excessive promises and hurried generalisations.
How to untangle a headline in half a minute
Underline the name used and find the first sentence identifying the material. Then check whether the cited study investigated that same product. Finally, distinguish the scientific description from the legal classification: one explains the object; the other requires consulting rules and their scope. When those pieces fit, the news story becomes much easier to understand and compare with the next one.
Take this with you
Material and process clarify more than a device’s silhouette. Vaporiser needs context; electronic cigarettes and heated tobacco should be distinguished.
