Good evening,Heated cigarette blogger Genki (@MOQLOG_JP)It is.

In this article,Are Icos more harmful than cigarettes?I have been writing about this industry for many years and have written about the question ofHeated Cigarette Bloggerwill explain.

With the recent boom in smoking cessation, a variety of products have been launched and debated as to whether they are safe or not. Even for Icos, the leading product in this category, there are many rumors flying around.

The keywords of interest this time around are.10 times more carcinogenicIf you have been wondering about the harmfulness of Icos, please refer to this article.

The Harms of Icos

IQOS is the world's number one cigarette companyPhilip MorrisYou are referring to a brand of heated cigarettes marketed by

The claim that has remained unchanged since then is that it reduces harmful substances by 951 TP3T compared to paper cigarettes! and it can be said to be the product that laid the foundation for a new tobacco culture that replaced paper cigarettes.

IQOSincludingHeated tobaccodoes not burn tobacco leaves, but only heats them with the power of electricity, which produces very little tar and carbon monoxide, which is the reason for the 95% reduction.

Such is the case with Icos, but in May 2017, surprising news spread and caused a bit of a stir. That is exactly what it was! That's what it was called.

Icos "10 times more carcinogenic" rumor

One domestic media site translated information from a foreign news site.

The original source was the popular Reuters news agency in Japan, which investigated IQOS ingredients at a time when IQOS was just beginning to be sold worldwide! This is a hot topic.

Moreover, some toxic substances were detected at higher levels than in cigarettes! The report was that some toxic substances were detected at levels higher than those of paper cigarettes!

It's a topic that media operators would jump on, and the translation and reprinting of it was the genesis of the news that caused such a fuss in Japan.

Icos "10 times more carcinogenic" news

Recent experiments suggest that new types of "no heat burning" cigarettes release some of the same carcinogenic chemicals found in traditional cigarette smoke.
-Omitted.
The team was surprised to find that heated cigarettes "released some of these chemicals in much higher concentrations than conventional cigarettes," said Dr. Auer, lead researcher at the University of Bern in Switzerland.
-Omitted.
IQOS smoke did contain harmful chemicals, but in lower concentrations on average," Auer said. More research needs to be done to determine if IQOS is safer for users and bystanders."
This is an excerpt from a Japanese translation of the text translated by Google Translate. Please refer to the reference link for the full text.

Two key points about Auer's paper are as follows.

The truth about Icos "10 times more carcinogenic

Despite the conclusion that "on average, concentrations were low."10 times more carcinogenicThe rumor that it was included, and that it was spread, was due to an exaggerated title by the media that reprinted it.

The news spread just as the IQOS boom was in full swing and the new IQOS 2.4 Plus had just been released, sparking a wide range of opinions on social networking sites and the Internet.

That's right, IQOS, which claimed to have "reduced toxic substances by 90% compared to paper cigarettes," is, on the contrary, 10 times more carcinogenic than paper cigarettes! If that were the case, it would be a big deal.

Icos also refutes the claim! Carcinogenicity 10 times higher" is a hoax!

With news like this, IQOS officials cannot remain silent.

The results of this survey are not correct in the following respects, and we have presented them as our official response.

The 10-fold carcinogenicity spread in Japan is not only an exaggeration of the original news story, but also means that the study itself was not credible.

In other words,Carcinogenicity of Icosschool (e.g. of ikebana)10 times more than cigarettesThat is to say,Artificial hoaxSo it was!.

That is as I wrote in the description of Icos at the beginning of this article,Tar and carbon monoxide, the three most toxic substances in cigarettes, are hardly produced, though,Nicotine is present in these cigarettes to the same degree as in cigarettes.

It also has a smell and the way it is smoked is that of a cigarette itself, so it must be used in accordance with the same smoking rules as paper cigarettes.

Toxic Substances Ranking

Psychiatrist Mike Russellhes words, "Smoke cigarettes for the nicotine and die from the tar."
Nicotine is also harmful, but tar is much more harmful when considering the carcinogenic and other harmful effects of cigarettes.

Switching from Paper Cigarettes to Icos Improves Biological Response (News 2018)

PMI announced the results of its latest clinical trial on IQOS heated cigarettes. The Exposure Response Study (ERS) evaluated the biological response of adult smokers to continuous cigarette smoking versus switching to IQOS. 6 months later, the study results showed that IQOS was associated with a variety of diseases, including heart and lung disease, as well as biological mechanisms such as inflammation and oxidative stress. The results of the six-month study showed that switching to IQOS improved biological responses in eight primary clinical risk endpoints that have been linked to a variety of diseases, including heart and lung disease, as well as biological mechanisms such as inflammation and oxidative stress.

Icos are also tar buddies if not used correctly.."polycyclic aromatic hydrocarbon"(multidirectional interstitial hydrogen sulfide) occurs.

The old Icos is a device that must be cleaned, and after smoking, there is a blackened burnt residue that accumulates under the insertion port, you know, that thing.."polycyclic aromatic hydrocarbon"most frequently.

In other words, if you do not clean up well after smoking, you will waste the advantage of "no tar" that is one of the advantages of heated cigarettes.

Is icos ilma (terrier or sentia) harmful?

Icos Irma has (1) eliminated the blades and (2) greatly improved the structure of the dedicated cigarette sticks (Terrier and Sentia).

These two improvements prevent the accumulation of tobacco leaf debris in the heating system, which is why the."polycyclic aromatic hydrocarbon"also rarely occur anymore.

It is on this basis that the icos with blades had a 901 TP3T cut, while the icos Irma claims a 951 TP3T cut.
