## **Introduction**

Traditional smoking has long been associated with severe health risks, including cancer, heart disease, and respiratory illness, primarily due to the **harmful chemicals released during combustion**. Cigarettes burn tobacco at high temperatures, releasing smoke that contains thousands of toxic compounds.

In response to growing public health concerns, the tobacco industry introduced **heated tobacco products (HTPs)** like **IQOS**, which offer a new way to consume nicotine without burning tobacco. These devices **heat specially designed sticks** (HEETS or [TEREA](https://tereaheetsdubai.ae/iqos-terea/)) to produce vapour instead of smoke.

### But are heated tobacco products safer than traditional smoking?

This question has gained importance not just for **individual health decisions** but also in **public policy discussions** and **regulatory frameworks**especially in forward-thinking regions like the UAE, where harm reduction tools are gaining traction.

**In this blog, we’ll explore:**

- How heated tobacco works

- What makes it different from smoking or vaping

- The scientific evidence behind its health impact

- Regulatory views from the WHO, FDA, and UAE authorities

- Whether it’s a safer choice for adult smokers

## **What Is Heated Tobacco and How Does It Work?**

### 🔍** Definition: **Heated Tobacco Products (HTPs)

Heated tobacco, also known as **heat-not-burn**, refers to products that **heat real tobacco** to a controlled temperature without setting it on fire. Unlike cigarettes, which burn at over 600°C, these devices heat tobacco to around **350°C**, releasing a nicotine-containing aerosol rather than smoke.

### ⚙️ How Devices Like IQOS Operate

Devices such as [**IQOS ILUMA**](https://tereaheetsdubai.ae/iqos-iluma/)****[**IQOS 3 DUO**](https://tereaheetsdubai.ae/iqos-3-duo-kit/), and [**IQOS LIL SOLID**](https://tereaheetsdubai.ae/lil-solid-ez/) use advanced technology to heat tobacco sticks:

- **IQOS ILUMA** uses **induction heating**, which heats the tobacco from the core without a blade.

- **IQOS 3 DUO** and **LIL SOLID** use a ceramic heating blade inserted directly into the tobacco stick.

This results in a **smoke-free vapor** that contains significantly fewer harmful chemicals than traditional cigarette smoke.

### 🧩 Main Components:

- **IQOS Device** – Battery-powered unit with heating chamber

- [**HEETS**](https://tereaheetsdubai.ae/heets-classics-dubai/)** or TEREA Sticks** – Specially manufactured tobacco sticks for heating

- **Charger & Cleaning Tools** – Accessories to maintain the device (except ILUMA, which is blade-free)

Heated tobacco bridges the gap between **traditional smoking rituals** and **modern harm reduction tools**.

## **Combustion vs. Heating: The Key Scientific Difference**

The core health difference between traditional smoking and heated tobacco lies in **combustion**.

### 🔥 What Happens During Combustion

Burning tobacco creates over **7,000 chemicals**, including:

- **Tar**

- **Carbon monoxide (CO)**

- **Formaldehyde**

- **Ammonia**
Many of these compounds are **known carcinogens** and are toxic to the heart and lungs.

### 🌡️ What Happens When Tobacco Is Only Heated

When tobacco is heated (not burned), the chemical reaction is fundamentally different. The **lower temperature (approx. 350°C)** avoids combustion and drastically reduces:

- Harmful smoke constituents

- Tar and solid particles

- Carbon monoxide levels

### 🧪 Chemical Formation Comparison

This difference is why IQOS is often promoted as a **reduced-risk product** for adult smokers.

## **What Research Says About Health Risks**

### 📚 Scientific Studies Overview

- **Industry-funded studies** by Philip Morris International (PMI) show a significant reduction in harmful exposure.

- **Independent studies** (including [WHO](https://www.who.int/)-contracted reviews) agree that heated tobacco reduces toxin exposure but warn that **long-term effects are still unknown**.

### ⏱️ Short-Term Effects

Users of IQOS are exposed to **lower levels of harmful and potentially harmful constituents (HPHCs)** compared to smokers. These include:

- Acrolein

- Benzene

- Nitrosamines

### 🧬 Long-Term Data: Still Under Review

- Ongoing studies are tracking long-term **lung health, cardiovascular impact**, and **cancer risk**

- Some scientists urge caution, noting that **reduced exposure ≠ no risk**

### 🌐 WHO & FDA Positions

- **WHO**: Heated tobacco is “likely to be less harmful than cigarettes” but not recommended for non-smokers or youth

- **FDA**: In 2020, the FDA authorised IQOS as a **Modified Risk Tobacco Product (MRTP)**, recognising it **reduces exposure to harmful chemicals**

## **Comparing Health Impacts: Smoking vs. Heated Tobacco**

Let’s break down the potential benefits for adult smokers:

### ❤️ Cardiovascular Effects

- Cigarette smoke increases blood pressure and damages arteries

- Heated tobacco shows **less cardiovascular stress**, but long-term benefits are still under study

### 🫁 Lung and Respiratory Impact

- Smoking causes chronic bronchitis, emphysema, and lung cancer

- Heated tobacco emits **fewer respiratory irritants**, potentially reducing risk

### 🎗️ Cancer Risk Reduction

- Reduced levels of carcinogens in aerosol vs. smoke

- IQOS shows **90–95% fewer toxins** than traditional cigarettes in most studies

- Still not completely risk-free

### 🌬️ Passive Exposure (Secondhand Aerosol)

- Secondhand smoke from cigarettes is extremely harmful

- IQOS aerosol has **fewer toxins and less odor**

- Still not advisable to use around children or in enclosed public areas

## **Heated Tobacco vs. Vaping: Which Is Safer?**

Both **heated tobacco** and **vaping** are alternatives to traditional cigarettes, but they are **fundamentally different** in what they deliver and how they work.

### 🔬 Key Differences in Substance: Real Tobacco vs. E-Liquid

FeatureHeated Tobacco (e.g., IQOS)Vaping (e.g., Myle, NERD Bar)Base IngredientReal tobaccoNicotine salt e-liquidHeating MechanismTobacco is heatedE-liquid is vaporizedSmoke ProductionNo smoke (tobacco vapor)No smoke (nicotine vapor)TasteAuthentic tobacco flavorFlavored (fruity, mint, etc.)

Heated tobacco gives a **real tobacco experience** without burning, while vaping is entirely smoke-free but uses **synthetic nicotine liquids** in various flavors.

### 🧪 Health and Research Comparison

- **Heated Tobacco:** Research shows **significantly lower levels of toxicants** compared to cigarettes. It contains real tobacco but emits no smoke or ash.

- **Vaping:** Contains **no tobacco** at all, only nicotine. While vaping eliminates many of the harmful chemicals in smoke, questions remain about **long-term inhalation of flavoring agents** and additives.

So far, **heated tobacco may be more satisfying for smokers**, but **vaping may offer lower toxin exposure**, especially with quality-regulated devices.

### 😌 Taste, Ritual, and User Satisfaction

- **Heated Tobacco** mimics the feel of smoking more closely, including hand-to-mouth action, warmth, and tobacco aroma.

- **Vaping** appeals to those who prefer **flavored experiences** and less throat hit. It’s often smoother but can feel less “authentic” for traditional smokers.

### 🧍 Who Might Prefer One Over the Other?

- **Current smokers** looking for a similar feel: **Heated tobacco (IQOS)**

- **Users who enjoy flavor variety and smooth inhale**: **Vaping**

- **People trying to reduce toxin intake**: **Both are better than smoking**, but choice depends on personal habits and satisfaction levels.

## **What Experts and Regulators Say**

### 🌐 Opinions from Global Health Bodies

- **WHO**: Heated tobacco is *less harmful than smoking*, but still not safe. Discouraged for non-smokers.

- **FDA (USA)**: IQOS has **Modified Risk Tobacco Product (MRTP)** status. It reduces exposure to harmful chemicals but is not approved as “safe.”

- **CDC (USA)**: Warns against use by **youth, pregnant women**, and non-smokers.

### 📋 Regulatory Stance in UAE, EU & Beyond

- **UAE**: Heated tobacco and vaping are **legal and regulated**. Products must meet quality and labeling standards. Selling to minors is prohibited.

- **EU**: Strict regulations on advertising, packaging, and nicotine limits.

- **Japan & South Korea**: Heated tobacco is widely used and regulated under national tobacco laws.

Governments acknowledge the **harm reduction potential**, but **regulate them strictly** to prevent use among youth and non-smokers.

### 🚫 Warnings for Non-Smokers and Youth

Both products are **intended only for adult smokers** looking to reduce risk. Neither IQOS nor vapes are safe for:

- Non-smokers

- Pregnant women

- Teenagers or young adults

Using these products without prior nicotine exposure can lead to **addiction** and other health concerns.
