If you smoke in Dubai or Abu Dhabi, you may have come across IQOS while shopping for tobacco products. It looks different from a cigarette and works differently, too. Instead of burning tobacco, the device heats specially designed tobacco sticks.
But does that make IQOS a better choice?
The answer isn’t as simple as comparing smoke with aerosol. IQOS produces no cigarette ash, and its aerosol generally contains lower levels of certain harmful chemicals than cigarette smoke. It still delivers nicotine and exposes users to substances that can affect their health.
Here is how IQOS compares with cigarettes, including the differences that matter to adult smokers in the UAE.
How IQOS Works Compared With Cigarettes
A cigarette burns tobacco when lit. The burning process produces smoke containing nicotine, carbon monoxide and numerous harmful chemicals.
IQOS uses an electronic heating system to warm tobacco sticks without conventional combustion. The user inhales the resulting aerosol rather than cigarette smoke.
The practical differences are easy to see:
| Feature | Cigarettes | IQOS |
| Tobacco use | Burned | Heated |
| What you inhale | Smoke | Tobacco aerosol |
| Ash | Yes | No cigarette ash |
| Nicotine | Yes | Yes |
| Device required | No | Yes |
| Health risks | Serious and well established | Harmful exposure remains; long-term effects are still being studied |
IQOS is not a conventional vape. A vape typically heats liquid, while IQOS uses specially designed tobacco sticks.
The heating method changes the product’s emissions, but it does not remove the risks associated with tobacco.
Smell, Smoke and Ash
Cigarette smoke has a distinctive smell that can remain on clothes, in cars and around indoor spaces. Burning tobacco also leaves ash and cigarette butts.
IQOS produces a different-smelling aerosol and does not leave cigarette ash. Some users find its smell less noticeable than cigarette smoke, although the experience varies by product and setting.
That difference may be convenient for some adult users, but it should not be mistaken for proof of lower health risk. The aerosol still contains nicotine and other substances released during tobacco heating.
A product that smells less strongly can still expose its user and nearby people to potentially harmful chemicals.
Does IQOS Contain Nicotine?
Yes. TEREA and HEETS sticks contain tobacco, which naturally contains nicotine.
Nicotine is addictive. Regular IQOS use can maintain dependence, even if someone stops smoking conventional cigarettes.
Nicotine exposure varies with the product and the way a person uses it. One stick does not necessarily deliver the same amount of nicotine as one cigarette.
Switching to IQOS is therefore not the same as quitting nicotine. The product is intended for adult tobacco users, not non-smokers or young people.
If you want to stop smoking and end nicotine dependence, consider evidence-based quitting support rather than treating heated tobacco as a cessation product.
Tar and Harmful Chemicals
Burning tobacco creates a complex mixture of chemicals, including substances found in cigarette tar. Many of these emissions contribute to the health risks of smoking.
Heating tobacco produces a different mixture of emissions. Studies have found lower levels of certain harmful chemicals in IQOS aerosol than in cigarette smoke. However, the levels vary by substance, and some potentially harmful chemicals remain present.
Three things should not be confused:
- Lower levels of certain chemicals do not establish the same reduction in disease risk.
- Reduced exposure to some substances does not mean every harmful substance is reduced.
- A tobacco product with lower levels of certain emissions is not necessarily safe.
IQOS aerosol is not simply water vapour. It contains nicotine and other substances released from heated tobacco.
For an accurate comparison, look at independent research and public-health assessments, not just the manufacturer’s product claims.
Can IQOS Damage Your Lungs or Cause Cancer?
Cigarette smoking is a well-established cause of lung cancer, chronic respiratory disease and cardiovascular disease. Its long-term effects have been studied extensively.
Heated tobacco products have a shorter research history. Scientists have measured differences in chemical exposure, but the evidence on long-term disease outcomes remains limited.
That leaves an important gap between knowing what a product emits and knowing how much it changes a person’s lifetime risk of illness.
IQOS is not risk-free. Its aerosol contains nicotine and potentially harmful substances, and using it does not eliminate tobacco-related health concerns. It would be misleading to describe it as cancer-free or harmless to the lungs.
For someone who smokes, stopping tobacco use completely offers the clearest health benefit. A doctor or qualified healthcare professional can help with evidence-based options for quitting.
Pregnant people and those with existing heart or lung conditions should seek medical advice rather than rely on comparisons between tobacco products.
Is One IQOS Stick Equal to One Cigarette?
For everyday use, one TEREA or HEETS stick is generally intended for one session, much like one cigarette. Pack sizes vary, so check the quantity printed on the packaging before buying.
That does not make the two products medically equivalent.
Nicotine delivery and chemical exposure can differ between a cigarette and a heated tobacco stick. They also depend on how frequently and deeply a person inhales.
Someone who switches to IQOS but continues smoking cigarettes may still receive exposure from both products. Counting sticks alone cannot show whether that person’s overall health risk has changed.
IQOS vs Cigarettes: Cost in the UAE
The cost comparison includes more than the price printed on a pack.
With cigarettes, you mainly pay for each pack. IQOS requires an initial device purchase, followed by regular spending on compatible tobacco sticks.
| Expense | Cigarettes | IQOS |
| Initial cost | Cigarette pack | Device and tobacco sticks |
| Regular purchases | Cigarette packs | TEREA or HEETS packs |
| Extra expenses | Depends on personal use | Possible accessories or replacement parts |
| Main price consideration | Brand and pack price | Device cost, stick price and usage |
For UAE buyers, check the current price of the device and the exact stick edition before comparing the totals. Retail prices and availability can change.
You can estimate the monthly cost of tobacco sticks using this formula:
Monthly cost = pack price × packs used per day × 30
For example, at AED 20 per pack, using one pack daily would cost AED 600 over 30 days. This is an example calculation, not confirmation of the current price at every UAE retailer. The device cost would be additional.
A fair comparison should use current prices for both products and the amount you actually consume.
TEREA or HEETS: Which One Fits Your IQOS Device?
Buying the wrong sticks is an easy mistake to make if you are unfamiliar with IQOS models.
TEREA sticks are designed for compatible IQOS ILUMA devices. HEETS sticks are designed for compatible older blade-based IQOS devices. The two types cannot be used interchangeably.
For example:
- IQOS ILUMA
- IQOS ILUMA PRIME
- IQOS ILUMA i
- IQOS ILUMA i ONE
These ILUMA-family devices use compatible TEREA sticks. Older blade-based IQOS models use their designated HEETS sticks.
Before ordering in Dubai or another emirate, check the model name on your device and confirm compatibility. Do not choose sticks based only on their packaging or appearance.
Also verify the pack quantity, product edition and seller information. Availability can differ between retailers.
Who Should Not Use IQOS?
IQOS is not intended for non-smokers or young people. Starting to use tobacco when you do not already smoke introduces avoidable health risks and can lead to nicotine dependence.
It is also not a proven smoking-cessation treatment. Someone who wants to stop smoking should look into established quitting methods with support from a healthcare professional.
Using IQOS and cigarettes together does not guarantee a meaningful reduction in harmful exposure. Continuing to smoke cigarettes remains a major concern.
For adult smokers considering a change, health risks deserve more attention than product appearance, smell or convenience.
Frequently Asked Questions
Is IQOS safer than cigarettes?
IQOS produces lower levels of certain harmful chemicals than cigarette smoke, but that does not prove it is safe or establish the size of any difference in long-term health risks.
Is IQOS less harmful than cigarettes?
The products differ in their emissions, and some harmful chemical exposures are lower with IQOS. Long-term health outcomes are not sufficiently established to assign a reliable overall risk reduction.
Does IQOS contain nicotine?
Yes. IQOS uses tobacco sticks containing nicotine, an addictive substance. It is not a nicotine-free alternative.
Does IQOS produce tar?
IQOS does not burn tobacco in the same way as a cigarette, so its aerosol differs from cigarette smoke. Its emissions can still contain potentially harmful substances, and they should not be described as harmless.
Can I buy TEREA in Dubai?
TEREA is available through tobacco-product retailers in the UAE, although prices, editions and stock can vary. Check the current availability and confirm that the sticks match your ILUMA device.
Can IQOS help me quit smoking?
IQOS is not an established smoking-cessation treatment. If your goal is to stop smoking, ask a healthcare professional about evidence-based quitting support.
Is IQOS a vape?
No. IQOS heats tobacco sticks, while conventional vapes heat a liquid. Both can deliver nicotine, depending on the product, but they work differently.
