Smoke released from heat-not-burn tobacco cigarettes contains the same
harmful components as conventional tobacco cigarette smoke, according to
data published in JAMA Internal Medicine.To get more news about Hitaste Q1, you can visit hitaste.net official website.
“The tobacco industry’s most recent response to the documented harms
of cigarette smoking was to launch new heat-not-burn (HNB) tobacco
cigarettes,” Reto Auer, MD, MAS, from the Institute of Primary Health
Care at the University of Bern in Switzerland, and colleagues wrote.
“Philip Morris International created IQOS (I-Quit-Ordinary-Smoking):
disposable tobacco sticks soaked in propylene glycol, which are inserted
in a holder in the HNB cigarette.”
“Philip Morris International claims that IQOS releases no smoke
because the tobacco does not combust and the tobacco leaves are only
heated not burned,” they added. “However, there can be smoke without
fire. The harmful components of tobacco cigarette smoke are products of
incomplete combustion (pyrolysis) and the degradation of tobacco
cigarettes through heat (thermogenic degradation).”Auer and colleagues
analyzed and compared the contents and toxic compounds released in IQOS
(IQOS Holder, IQOS Pocket Charger, Marlboro HeatSticks [regular], and
Heets, Philipp Morris SA) smoke with conventional cigarettes (Lucky
Strike Blue Lights). They used gas chromatography paired with a flame
ionization detector to assess volatile organic compounds and nicotine,
as well as high-performance liquid chromatography paired with a
fluorescence detector to assess polycyclic aromatic hydrocarbons.
Data indicated that IQOS smoke contains similar levels of volatile
organic compounds and nicotine as conventional cigarettes. In addition,
heat-not-burn cigarettes released higher levels of the polycyclic
aromatic hydrocarbon acenaphthene than conventional cigarettes. Other
polycyclic aromatic hydrocarbons and carbon monoxide were also present
in IQOS smoke. IQOS had a lower temperature than the conventional
cigarette (330 C vs. 684 C). Eighty-four percent of nicotine found in
conventional cigarette smoke was present in IQOS smoke.“The smoke
released by IQOS contains elements from pyrolysis and thermogenic
degradation that are the same harmful constituents of conventional
tobacco cigarette smoke,” Auer and colleagues concluded. “Our analyses
reveal that advertising slogans such as ‘heat-not-burn’ are no
substitute for science. Dancing around the definition of smoke to avoid
indoor-smoking bans is unethical.”
The researchers call for further evaluation of the health effects of
IQOS, but insist that heated tobacco products be subjected to the same
indoor-smoking bans as conventional tobacco cigarettes.
In an accompanying editor’s note, Mitchell H. Katz, MD, from the Los
Angeles County Department of Health Services, noted that while
heat-not-burn tobacco cigarettes are not yet for sale in the United
States, PMI has applied to sell these products with the FDA.“These
products threaten the progress that has been made on decreasing the
harms of second-hand smoke because existing bans may not apply to these
heat-not-burn products,” he wrote. “However, as convincingly reported by
Auer and colleagues, although these products may or may not produce
smoke, they release cancer-causing chemicals.”
