We believe in science. We believe we can change the lives of millions of adult smokers, who would otherwise continue smoking. For this purpose, we commissioned scientists to focus on the development of new products, which adult smokers can switch to if they want a better alternative to cigarettes. Hundreds of scientists and engineers at the PMI global research and development centers in Switzerland and Singapore joined forces to develop and thoroughly test IQOS - an innovative electronic device that does not burn tobacco, but heats it. It produces aerosol, which adds a tobacco flavor and nicotine.

Heating technology

 

When a cigarette is lit, the tobacco burns at temperatures of around 600°C. Smoke and ash are created in this process. When a smoker takes a drag of the cigarette, the temperature at the tip may rise to over 800°C. Cigarette smoke is a mix of more than 6,000 chemical substances, of which public health authorities associate 100 with smoking-related diseases

Why heating is better

IQOS does not burn tobacco, but merely heats it. The reason is simple: burning tobacco creates a large quantity of harmful chemical substances. IQOS HeatControl™ technology does not burn tobacco, but merely heats it, which means that compared to cigarette smoke, it significantly reduces the quantity of harmful chemical substances produced.

DISCOVER

IQOS HeatControl™ technology heats tobacco at a lower temperature (300 - 320°C)**, which ensures that it does not burn. Because there is no burning, IQOS does not produce any smoke. It creates tobacco aerosol, which brings you the finest quality taste of tobacco, but contains 95% fewer harmful chemicals compared to cigarettes.

Important information: This does not necessarily means a reduction of risk by 95%. IQOS is not risk-free.

“95% less” is the average reduction in the level of a wide range of harmful chemical substances (except nicotine) compared to smoke from the reference cigarette (3R4F). More information at www.IQOS.com.

** The maximum temperature of 300 °C was measured for tobacco at a distance of 0.2 mm from the heating blade, the maximum temperature of 320 °C was measured for tobacco directly touching the heating blade.

Is using IQOS less harmful to health?


Science_less toxic_PeopleNoHeets_1

 

In laboratory conditions, we discovered that the aerosol from IQOS devices is less toxic compared to cigarette smoke.

Our scientists thoroughly test all of our products before they are delivered to adult smokers. Using in vitro tests at our laboratories, we evaluated the cycotoxicity and genotoxicity of tobacco aerosols from IQOS devices compared to smoke from the reference cigarette for research purposes. The summarized results of these tests indicate that aerosol generated by the IQOS device is significantly less toxic than smoke from the reference cigarette.

And that is just a small part of our work. From these laboratory tests, we progressed to testing IQOS with thousands of adult smokers, who volunteered to join our program for clinical studies and finally allowed us to introduce our products to the market.

Testing according to the highest standards

The IQOS device underwent rigid scientific evaluation, including 18 non-clinical and 10 clinical studies involving thousands of participants performed to date. The summary of available data shows that while the use of an IQOS device is not risk-free, switching entirely to IQOS poses a lower risk to your health than continuing to smoke cigarettes.*

Clinical studies

 

Does a significantly lower number and quantity of harmful chemical substances in IQOS aerosol also mean a lower level of these chemical substances in the body? If the level of chemical substances in the aerosol from IQOS is lower, it might be assumed that switching entirely from cigarettes to IQOS will reduce exposure to these harmful substances. In order to prove this, we measured the exposure biomarkers for a range of these chemical substances among thousands of smokers, who participated in our clinical study program (some switched to IQOS while others either continued smoking their cigarette brand, or quit smoking during the study).

FIND OUT MORE

The results of these studies indicate that when adult smokers switch to IQOS, their body absorbs significantly lower levels of harmful chemical substances, which leads to positive changes in a number of risk markers, which were chosen due to their known links to smoking-related diseases.

Satisfaction with IQOS


Science_satisfaction_PeopleNoHeets_1

 

Participants in our clinical study who switched to IQOS also state that IQOS provides a comparable rate of satisfaction to cigarettes. This supports our opinion that IQOS has the potential to be an acceptable alternative for adult smokers who would otherwise continue smoking. Based on all the scientific evidence, we are convinced that switching entirely to IQOS is less harmful than continuing to smoke cigarettes. 

Important information: IQOS is not risk-free and the degree of reduced risk depends also on the frequency and use by each individual. The absolutely best choice remains to quit using tobacco and nicotine entirely. IQOS is not an alternative to quitting smoking. It contains nicotine, which is addictive.

Indoor air quality

 

Indoor air quality (“IAQ") indicates the quality of air in buildings, generally based on the principle of ensuring the health and comfort of the building’s users. Temperature, humidity and impurities are some of the factors that can affect indoor air quality. However, it was proven that human presence and activities such as cooking, cleaning or smoking, have a major impact on indoor air quality.
In order to expand our expertise and understand the impact of IQOS on indoor air quality, we conducted a study simulating the “real” conditions in a room with a controlled environment. Our trial methods are validated and accredited by ISO.

FIND OUT MORE

The results of the study confirmed that the use of IQOS has no negative impact on indoor air quality, because it does not burn tobacco and generates no smoke. This means that the few substances which we detected nevertheless in the air, were found in very small concentrations and far below the maximum exposure level defined in current regulations regarding indoor air quality.

Tobacco sticks and nicotine pods used with IQOS contain nicotine, which is addictive. Therefore using IQOS is not risk free. The best choice for consumers concerned about their health is to quit tobacco and nicotine use altogether.
