TEREA, DELIA and LEVIA may share the same SMARTCORE stick format, but they are not simply three versions of the same product. TEREA offers the broadest tobacco-led range, DELIA focuses on accessible classic tobacco profiles, while LEVIA replaces tobacco with a plant-derived carrier for a distinctly aromatic experience.
TEREA vs DELIA vs LEVIA: the short answer
The biggest difference is the material inside the stick. Both TEREA and DELIA contain tobacco. LEVIA contains no tobacco, but it still contains addictive nicotine added to a plant-derived base. That makes LEVIA an alternative flavour format, not a nicotine-free product.
All three ranges are made for the IQOS ILUMA and ILUMA i families. They should not be inserted into older blade-based IQOS devices. Check our IQOS stick compatibility guide before switching between device generations.
TEREA
The strongest choice for variety. It covers classic tobacco, menthol, aromatic and capsule-style options, with the widest availability of the three ranges.
DELIA
A more focused tobacco range built around familiar, uncomplicated profiles. It is often positioned as the more affordable alternative to TEREA.
LEVIA
A zero-tobacco nicotine range aimed at users who prefer cooling, fruity or aromatic sensations without a traditional tobacco character.

Availability warning: there is no single worldwide TEREA, DELIA or LEVIA catalogue. Flavour ranges, legal restrictions and prices vary by country, so a product sold in one IQOS market may be unavailable in another.
What is actually inside TEREA, DELIA and LEVIA?
The outside format is deliberately similar because all three products use the SMARTCORE induction system found in IQOS ILUMA devices. The important difference is inside the stick: TEREA and DELIA heat real tobacco, while LEVIA heats a tobacco-free, plant-derived substrate containing added nicotine and flavour.
What is inside TEREA?
TEREA contains processed tobacco surrounding a metal heating element. The stick is sealed at both ends, allowing an IQOS ILUMA device to heat it internally without using the ceramic blade found in older IQOS generations.
Different TEREA variants combine tobacco blends with menthol, aromatic notes or crushable flavour capsules. The tobacco character may be prominent or subtle, but tobacco remains part of every TEREA stick.
What is inside DELIA?
DELIA also contains tobacco and uses the same sealed SMARTCORE format. Its physical size and heating principle are effectively the same as TEREA, so the difference is primarily the flavour portfolio and market positioning rather than a new technology.
The range is built around simpler, recognisable tobacco profiles. DELIA therefore feels more like a focused alternative to TEREA than a completely different stick category.
What is inside LEVIA?
LEVIA replaces tobacco with a neutral, cellulose-based material made mainly from plant-derived ingredients. Nicotine and flavour are added to this substrate before it is formed into a stick compatible with IQOS ILUMA.
Because there is no tobacco blend shaping the taste, LEVIA can deliver brighter cooling, fruit and aromatic profiles without the roasted or woody background associated with heated tobacco.
Important: “Zero tobacco” does not mean “zero nicotine.” LEVIA contains nicotine and is intended only for adults who already use nicotine products.
Which one has more nicotine?
There is no reliable worldwide nicotine ranking that places TEREA, DELIA and LEVIA from strongest to weakest. Product formulations and labelling can differ between markets, while IQOS does not publish one universal comparison figure covering every flavour in all three ranges.
More importantly, flavour intensity is not the same as nicotine content. A deeply cooling LEVIA or menthol TEREA variant can feel sharper than a mild tobacco stick, but that sensation does not prove that it delivers more nicotine. Likewise, a dark or roasted tobacco flavour may taste stronger without containing a higher nicotine dose.
| What affects the perceived strength? | How it changes the experience |
|---|---|
| Tobacco blend | Darker, roasted or woody profiles can create a heavier and fuller sensation. |
| Menthol cooling | Strong cooling can make a stick feel sharper even when nicotine content is not higher. |
| Aromatic flavour | Fruit, spice and capsule notes can increase flavour impact without increasing nicotine. |
| User behaviour | Puff frequency, depth and session length can influence perceived satisfaction. |
| Personal tolerance | Regular nicotine use affects how strong or satisfying the same stick feels. |
If your priority is a more intense taste rather than a laboratory nicotine number, use our guide to the strongest TEREA flavours. It separates tobacco richness, menthol cooling and overall flavour intensity instead of treating them as the same thing.
Our verdict on nicotine: do not choose between TEREA, DELIA and LEVIA based on an assumed nicotine hierarchy. Choose by tobacco content and flavour style, then check the packaging and official information for the specific product sold in your country.
How do TEREA, DELIA and LEVIA taste different?
The practical difference becomes clearer after the first few sessions. TEREA builds flavour around heated tobacco, DELIA keeps that tobacco character simpler and more traditional, while LEVIA puts the added flavour first because there is no tobacco blend underneath it.
TEREA: layered and varied
TEREA offers the broadest spectrum. Depending on the market, the range can include mellow, toasted and dark tobacco blends, different levels of menthol cooling, aromatic variants and Pearl sticks with crushable flavour capsules.
For example, TEREA Silver has a balanced toasted profile, Amber adds woody and nutty notes, while Blue combines tobacco with deeper peppermint cooling. Pearl variants can change noticeably after the capsule is activated.
DELIA: direct and familiar
DELIA is less about unusual flavour combinations and more about recognisable tobacco. Its profiles are generally easier to understand: lighter, balanced or richer tobacco, sometimes supported by restrained nutty, malty or refreshing notes.
That smaller selection is not necessarily a disadvantage. Someone who repeatedly buys one uncomplicated tobacco flavour may find DELIA easier to navigate than the much larger TEREA catalogue.
LEVIA: bright and aromatic
LEVIA has no underlying tobacco flavour, allowing cooling, fruit and aromatic notes to feel cleaner and more prominent. The experience can resemble a modern flavoured nicotine product more than a traditional heated tobacco stick.
Current examples in selected markets include deep peppermint cooling and Pearl combinations such as strawberry with watermelon, citrus with peppermint, and blueberry with strawberry. Availability differs significantly by country.
Which range matches your taste?
| Your preference | Best match | Why |
|---|---|---|
| Traditional tobacco | DELIA or TEREA | Both contain tobacco, but DELIA generally keeps the flavour profile simpler and more classic. |
| Maximum variety | TEREA | It usually offers the widest mix of tobacco, menthol, aromatic and capsule options. |
| Rich tobacco character | TEREA | The stronger TEREA blends provide more depth and a wider choice of roasted, woody and malty notes. |
| Simple everyday flavour | DELIA | Its focused catalogue makes it easier to settle on one familiar tobacco profile. |
| Fruit without tobacco | LEVIA | The neutral plant-derived base allows fruit and aromatic notes to dominate the session. |
| Strong cooling | TEREA or LEVIA | Both ranges include cooling options, but LEVIA delivers them without an accompanying tobacco taste. |
| Capsule experience | TEREA Pearl or LEVIA Pearl | Selected variants let you activate an additional flavour during the session. |
Closest to cigarettes? None of these products recreates cigarette combustion. However, tobacco-focused DELIA and stronger classic TEREA variants will generally feel more familiar to an adult smoker than fruit-led LEVIA.
Which one tastes best?
TEREA wins on overall flavour quality and selection. It offers enough variety to serve traditional tobacco users, menthol users and those who prefer more experimental capsule blends. Browse our complete worldwide TEREA flavour guide to see how extensive the range has become.
DELIA is the more practical choice when you want a dependable tobacco profile without paying for or navigating a premium-sized catalogue. LEVIA is the clear choice when the absence of tobacco matters more than recreating a familiar heated-tobacco taste.
New IQOS ILUMA users who are unsure where to start should compare our best TEREA flavours before moving to DELIA or LEVIA. TEREA remains the most useful baseline for understanding what the device can deliver.
Flavour winner: TEREA. DELIA is easier and often more economical, while LEVIA is more distinctive, but TEREA provides the strongest combination of depth, variety and availability.
Do TEREA, DELIA and LEVIA work in the same IQOS?
Yes. All three stick ranges use SMARTCORE induction technology and are designed for the IQOS ILUMA and IQOS ILUMA i families. This includes the standard, PRIME and all-in-one ONE models.
They are not compatible with IQOS ORIGINALS, IQOS 3 DUO, IQOS 2.4 Plus or any other device that heats tobacco with a blade. They also cannot be used with glo, lil SOLID or unrelated heated-tobacco systems.
| Device | TEREA | DELIA | LEVIA |
|---|---|---|---|
| IQOS ILUMA | Compatible | Compatible | Compatible* |
| IQOS ILUMA PRIME | Compatible | Compatible | Compatible* |
| IQOS ILUMA ONE | Compatible | Compatible | Compatible* |
| IQOS ILUMA i range | Compatible | Compatible | Compatible* |
| IQOS ORIGINALS and older blade devices | Not compatible | Not compatible | Not compatible |
| glo, lil SOLID and other systems | Not compatible | Not compatible | Not compatible |
*Before using LEVIA: IQOS recommends installing the latest available device firmware because LEVIA is heated differently from TEREA. Firmware support and update methods may depend on the device and market.
If you own an older IQOS model, read our TEREA vs HEETS comparison before inserting a stick. Using a sealed SMARTCORE stick in a blade-based device can damage the heating blade.
Does the session performance change?
Under standard operation, TEREA, DELIA and LEVIA are designed to provide a session of up to approximately six minutes or 14 puffs, whichever comes first. Actual duration can vary with puffing behaviour and the specific features supported by the device.
Most balanced experience
TEREA feels like the reference product for IQOS ILUMA. It combines the widest flavour selection with the familiar session format around which the ILUMA system was originally built.
Similar technical performance
DELIA does not meaningfully change the device’s heating speed, battery capacity or standard session length. Its main difference is the simpler tobacco flavour profile and price positioning.
Different taste, familiar format
LEVIA changes the flavour and aroma rather than turning IQOS into a different device. Once the required firmware support is available, it follows the same familiar insertion and heating process.
Performance verdict: none of the three ranges provides a meaningful battery or speed advantage. The device determines the technical experience; the stick determines whether that experience is tobacco-led, classic and simple, or tobacco-free and aromatic.
Can you switch between them in the same device?
You can alternate between compatible TEREA, DELIA and LEVIA sticks without buying a separate IQOS ILUMA device. However, LEVIA may require a firmware update before its first use.
Before inserting a different stick
- Confirm that the device belongs to the IQOS ILUMA or ILUMA i family.
- Install the latest available firmware before trying LEVIA.
- Use only genuine, undamaged sticks intended for your market.
- Never cut, open, ingest or attempt to reuse a SMARTCORE stick.
- Allow a used stick to cool before disposing of it responsibly.
Safety warning: SMARTCORE sticks contain a sharp internal metal component. Keep unused and discarded sticks away from children and pets, and never disassemble them.
Which range is easiest to find?
TEREA has the strongest international presence and is normally the easiest range to find through official IQOS stores and authorised retailers. DELIA and LEVIA are sold in fewer markets, while their local flavour selections can be considerably smaller.
TEREA
TEREA is the main consumable range for IQOS ILUMA in most supported markets. It generally receives the largest catalogue, including classic tobacco, menthol, aromatic and country-specific variants.
DELIA
DELIA availability is expanding, but the range remains much smaller than TEREA. Some countries offer only a few classic variants, while others do not officially sell DELIA at all.
LEVIA
LEVIA is the least predictable internationally. The number of flavours, capsule options and supported devices should always be checked through the official local IQOS website.
Important for travellers: do not assume that your usual sticks will be sold at your destination. Check our guide to TEREA flavours by country and verify current local nicotine-product rules before travelling.
Which range is cheaper?
DELIA is generally positioned as the more affordable tobacco alternative to TEREA. LEVIA can also be competitively priced, but its position varies because tobacco-free nicotine products are taxed and regulated differently across markets.
| Range | Typical positioning | What affects the final price? |
|---|---|---|
| TEREA | Mainline or premium option | Broad distribution, large flavour range and local tobacco taxation |
| DELIA | Usually the value-focused tobacco option | Official availability, smaller catalogue and local promotions |
| LEVIA | Varies significantly by country | Nicotine-product taxation, local availability and retailer pricing |
The cheapest option therefore depends on where you live. In an official DELIA market, DELIA will often provide better value than TEREA. However, imported DELIA or LEVIA can easily cost more than locally distributed TEREA once shipping and reseller margins are included.
Price verdict: DELIA is usually the best-value range when sold officially. TEREA often costs more but provides better availability and considerably more choice. Compare current local prices rather than relying on prices from another country.
Which one should you buy?
| User type | Recommended range | Reason |
|---|---|---|
| New IQOS ILUMA user | TEREA | It provides the best introduction to the system and the widest selection for finding your preferred profile. |
| Classic tobacco user | DELIA | The smaller catalogue focuses on straightforward tobacco rather than elaborate flavour combinations. |
| Strong tobacco user | TEREA | TEREA generally offers more rich, roasted and full-bodied tobacco options. |
| Menthol user | TEREA | It usually provides more cooling levels and tobacco-to-menthol combinations. |
| Fruit and capsule user | LEVIA or TEREA Pearl | LEVIA puts fruit first, while TEREA Pearl combines an activated flavour with a tobacco base. |
| User avoiding tobacco | LEVIA | LEVIA contains nicotine but uses a tobacco-free, plant-derived substrate. |
| Budget-focused user | DELIA where officially sold | DELIA is normally positioned as the more accessible tobacco option, without sacrificing ILUMA compatibility. |
| Frequent traveller | TEREA | It has the broadest international distribution and is generally easier to replace abroad. |
Best buying strategy: start with TEREA unless you have a specific reason not to. Choose DELIA for simpler tobacco and potential savings, or LEVIA when a tobacco-free flavour experience is the main priority.
Frequently asked questions
Are TEREA, DELIA and LEVIA the same?
No. TEREA and DELIA contain tobacco, while LEVIA uses a tobacco-free plant-derived substrate. They also differ in flavour selection, availability and price positioning.
Does LEVIA contain nicotine?
Yes. LEVIA contains nicotine even though it does not contain tobacco. It is not a nicotine-free product and is intended only for adult nicotine users.
Which range is the strongest?
There is no reliable universal nicotine ranking. Perceived strength depends on the individual variant, tobacco richness, cooling level, added flavour and personal nicotine tolerance.
Can all three be used in the same IQOS?
Yes, provided the device belongs to the IQOS ILUMA or ILUMA i family. IQOS recommends installing the latest available firmware before using LEVIA.
Can they be used with IQOS 3 DUO?
No. TEREA, DELIA and LEVIA contain an internal metal heating component and must not be inserted into IQOS 3 DUO, IQOS ORIGINALS or other blade-based devices.
Is DELIA cheaper than TEREA?
DELIA is normally positioned as the more affordable tobacco range where it is officially sold. Local taxes, promotions and import costs can still reverse the price difference.
Which tastes closest to a cigarette?
Tobacco-focused DELIA and stronger classic TEREA variants are generally the closest options. LEVIA tastes more aromatic because it contains no tobacco.
Is LEVIA risk-free because it has no tobacco?
No. Zero tobacco does not mean risk-free. LEVIA contains addictive nicotine and should not be treated as a cessation product or a harmless alternative.
Which range is best for beginners?
TEREA is the best starting point because it offers the widest selection and represents the standard IQOS ILUMA experience. DELIA and LEVIA serve more specific preferences.
Final verdict: TEREA vs DELIA vs LEVIA
TEREA is the overall winner. It has the broadest flavour selection, the strongest international availability and enough variety to suit classic tobacco, menthol and capsule users. For most IQOS ILUMA owners, it remains the safest range to choose first.
Choose TEREA if…
You want the widest selection, stronger international availability and the most complete IQOS ILUMA experience.
Choose DELIA if…
You prefer uncomplicated classic tobacco and DELIA is officially available at a lower price in your market.
Choose LEVIA if…
You specifically want cooling, fruit or aromatic nicotine flavours without an underlying tobacco character.
Our recommendation: begin with TEREA, move to DELIA for simplicity and value, and choose LEVIA only when the tobacco-free format is a deliberate preference rather than an assumption that it contains no nicotine.
