IQOS TEREA, nicotine pouches or snus? The great comparison of nicotine alternatives

The search for alternatives to traditional cigarettes has led to a growing variety of products. In addition to the well-known nicotine pouches and traditional snus, which you can find on snustrend.com, heat-not-burn tobacco products like the IQOS system are also gaining popularity. But how do these approaches differ? In particular, the new IQOS ILUMA system with its TEREA sticks raises questions. This article sheds light on IQOS TEREA and compares it to established oral nicotine products, based on a comprehensive analysis of technology, application, and risk profile.

What is IQOS TEREA? A closer look at the heat-not-burn device

IQOS, developed by Philip Morris International (PMI), is the leading brand in the field of heat-not-burn devices. The basic principle: real tobacco is heated electronically, but not burned.

• Technology: The latest generation, IQOS ILUMA, uses the SMARTCORE INDUCTION SYSTEM™. A magnetic field heats a small metal element inside the TEREA stick to heat the tobacco from the inside out to up to 350°C. Important: There is no heating blade in the device itself ("bladeless").
• TEREA Sticks: These specially designed sticks contain processed tobacco and the mentioned metal element. They are sealed on both sides, which makes cleaning the device unnecessary, but also means that they are exclusively compatible with IQOS ILUMA devices (not with older IQOS models or other devices).
• Advertised benefits (vs. cigarettes): PMI emphasizes: No smoke, no ash, less lingering odor, and "95% fewer harmful substances" (referring to 9 specific substances compared to a reference cigarette, excluding nicotine – which does not equate to a 95% risk reduction).
• User experience: Often described as an improvement over older models (no cleaning, flavor consistency, easy draw). A usage unit lasts about 6 minutes or 14 puffs.

What are nicotine pouches & snus? The established oral alternatives

In contrast to heat-not-burn devices, snus and nicotine pouches work without electronics and heating:

• Snus: A traditional Scandinavian product. Moist or dry tobacco is placed in small pouches (portions) or loose under the upper lip. The nicotine is absorbed through the oral mucosa.
• Nicotine pouches: The tobacco-free evolution. They contain nicotine (often in salt form), fillers (e.g., plant fibers), flavors, and humectants. The application is identical to portion snus – simply place under the lip.

The crucial difference to IQOS TEREA: No device, no heating, no tobacco vapor (aerosol), but direct nicotine absorption in the mouth. Nicotine pouches also offer the advantage of being completely tobacco-free.

Risks in comparison: A critical examination (Based on meta-analysis)

Assessing health risks is complex and not conclusively clarified. Important: None of these products are risk-free.

IQOS TEREA risks:

• Reduced exposure vs. risk: Studies confirm reduced exposure to some harmful substances compared to cigarette smoke. However, this does not automatically mean a proportionally reduced disease risk. Long-term effects are unknown.
• Own risks: Independent research points to potentially increased concentrations of other toxins (e.g., acenaphthene), the release of concerning substances (e.g., diacetyl in certain varieties, formaldehyde cyanohydrin), and negative effects on the heart, circulation, and respiratory system.
• Metal element: The internal metal part poses a serious choking hazard (especially for children) and raises questions about potential metal release during heating.
• Addiction: Contains nicotine and is highly addictive, comparable to cigarettes.
• Youth protection: Marketing and design are criticized for potentially appealing to youth.

Nicotine pouches & snus risks:

• Nicotine addiction: The main risk with intended use is nicotine dependence, similar to IQOS.
• Snus (tobacco-containing): Traditional snus (especially outside Sweden) is associated with certain health risks (e.g., oral cavity cancer). Swedish snus is often considered less risky but still carries risks.
• Nicotine pouches (tobacco-free): Since they do not contain tobacco, the specific risks from tobacco combustion or tobacco ingredients (such as tobacco-specific nitrosamines) are eliminated. The risks are primarily limited to the effects of nicotine itself and potentially the additives (flavors, etc.), with long-term data also lacking here. However, they are generally considered less harmful than products that burn or heat tobacco.
• No combustion/inhalation: A significant difference from IQOS and cigarettes is the absence of any combustion or heating processes and the oral rather than pulmonary absorption, which spares the lungs.

Conclusion on risks: All products contain the addictive nicotine. While IQOS reduces some harmful substances from combustion, it potentially introduces new risks, and the long-term effects are unclear. Nicotine pouches eliminate tobacco risks but retain the nicotine risk. Snus lies in between. Complete abstinence from nicotine and tobacco is always the safest option.

Who is suitable for which alternative?

• IQOS TEREA: Could be an option for adult smokers who:
  • want to maintain the smoking ritual and the taste of heated tobacco.
  • are looking for an alternative with potentially reduced harmful exposure (compared to cigarettes) but accept the remaining and new risks.
  • are willing to invest in an electronic device and use/load it.
• Nicotine pouches: Ideal for users who:
  • consume nicotine but want to completely avoid tobacco.
  • prefer a simple, discreet, device-free application.
  • value a smoke- and vapor-free experience.
  • are looking for a wide variety of flavors.
• Snus: For traditional users who:
  • want to experience the taste of real tobacco orally.
  • are looking for a device-free alternative to smoking.
  • are willing to accept the specific risks of tobacco (even without combustion).

Conclusion: IQOS TEREA vs. nicotine pouches/snus – A personal decision

IQOS TEREA, nicotine pouches, and snus offer different approaches as alternatives to smoking. IQOS relies on technology and heated tobacco to come close to the smoking experience but brings specific risks and the need for a device. Nicotine pouches offer a tobacco-free, simple, and vapor-free oral nicotine intake. Snus is the traditional tobacco-containing oral option.

The choice largely depends on your personal preferences: Do you prefer tobacco flavor or tobacco-free enjoyment? Is a simple application without a device important to you? How do you assess the different risk profiles?
