NEW
YORK – A new type of “heat-not-burn” cigarette releases some of the
same cancer-causing chemicals found in traditional cigarette smoke, a
recent experiment suggests.
Researchers analysed the
chemical compounds and nicotine in smoke from traditional cigarettes and
from the new devices, which are designed to heat disposable tobacco
sticks and give users the taste of tobacco without the smoke or ash.
The
smoke released by this “heat-not-burn” cigarette had 84% of the
nicotine found in traditional cigarettes, researchers report in JAMA
Internal Medicine.
Heat-not-burn cigarettes also
released chemicals linked to cancer including carbon monoxide, volatile
organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs).
The
research team was surprised to find that heat-not-burn cigarettes
“released some of these chemicals in much higher concentrations that
conventional cigarettes,” said lead study author Dr Reto Auer of the
University of Bern in Switzerland.
“We need more studies to find out about the health consequences” of smoking heat-not-burn cigarettes, Auer said by email.
“However,
there is no safe minimum limit for some of the chemicals” in
heat-not-burn cigarette smoke, Auer added, “and some of these chemicals
may contribute to the high mortality rate of smokers.”
To
see how heat-not-burn cigarettes compared to conventional cigarettes in
terms of chemicals released, Auer and colleagues analysed the smoke
from Lucky Strike Blue Lights and the newer alternative tobacco devices
using a smoking device developed to capture fumes from traditional and
electronic cigarettes.
They looked at the contents of
the I-Quit-Ordinary Smoking (IQOS) product from Philip Morris
International with an IQOS holder, IQOS pocket charger, Marlboro
HeatSticks regular and Heets.
While more studies are
needed to determine the long-term health effects of heat-not-burn
cigarettes, their use should be restricted until more is known about
them, Auer argues.
“Harmful chemicals were present in
IQOS smoke, though in lower concentrations, on average,” Auer said. “We
need to conduct more studies to find out whether IQOS are safer for
users or bystanders.”
Based on their findings, the
authors conclude that heated tobacco products should fall under the same
indoor smoking bans in place for conventional cigarettes to prevent
bystanders from breathing the fumes.
That’s because the
new tobacco products threaten the progress that has been made on
decreasing the harms of second-hand smoke, because existing bans may not
apply to heat-not-burn cigarettes, Dr Mitchell Katz, deputy editor of
JAMA Internal Medicine wrote in an editor’s note accompanying the study.
“There
is concern that heat-not-burn tobacco will skirt local ordinances that
prevent smoking in public areas,” Katz, director of the Los Angeles
County Health Agency, said by email.
“This would harm
public health by eroding social norms about the use of tobacco,” Katz
added. “In addition, the article demonstrates that heat-not-burn
products release carcinogens, so the use of these products in public
space would harm the health of both the user and those around the user.”
