FDA Proposes to Curb Sales of Flavoured E-cigarettes to Teenagers

The health regulator also proposed pre-market applications for all flavoured e-cigarette products that continue to be sold by August 8, 2021

The US Food and Drug Administration (FDA) has proposed to curb sales of flavoured e-cigarettes to teenagers.

The health regulator on Wednesday said that it is proposing to end all flavoured electronic nicotine delivery system (ENDS) products such as electronic cigarettes, except tobacco, mint and menthol-flavoured products.

According to the Centers for Disease Control and Prevention, a total of 3.6 million middle and high school students reported using e-cigarettes last year.

“Evidence shows that youth are especially attracted to flavoured e-cigarette products, and that minors are able to access these products from both brick-and-mortar retailers, as well as online, despite federal restrictions on sales to anyone under 18,” FDA Commissioner Scott Gottlieb, said in a statement.

“With these concerns in mind, today, we’re advancing our policies aimed at preventing youth access to, and appeal of, flavoured e-cigarettes and cigars.”

The new proposed policy also subjects all manufacturers and retailers to FDA enforcement for selling certain flavoured ENDS products without authorisation.

The FDA had previously threatened to ban most flavoured e-cigarettes in 2017 but did not take any enforcement moves.

However, with the new policy, FDA intends to prioritise its enforcement to focus on protecting youth from becoming addicted to nicotine.

It believes, at the same time, “that ENDS products still hold promise to help transition currently addicted adult smokers to potentially less harmful sources of nicotine”, Gottlieb said.

Carcinogen Metals Like- Lead, Nickel Found in E-Cigarettes

A team of US scientists has found that the concentration of carcinogen metals like lead, nickel, iron and copper in electronic cigarette aerosols, or vapour, has increased since tank-style electronic cigarettes were introduced in 2013.

Electronic cigarettes, which consist of a battery, atomizing unit and refill the fluid, are now available in new tank-style designs, equipped with more powerful batteries and larger capacity reservoirs for storing more refill fluid.

But the high-power batteries and atomizers used in these new styles can alter the metal concentrations that transfer into the aerosol, said researchers from the University of California, Riverside.

“These tank-style e-cigarettes operate at higher voltage and power, resulting in higher concentrations of metals, such as lead, nickel, iron, and copper, in their aerosols.

“Most of the metals in e-cigarette aerosols likely come from the nichrome wire, tin solder joints, brass clamps, insulating sheaths, and wicks, components of the atomizer unit,” said Monique Williams, a post-doctoral researcher and the first author of the paper that appeared in the journal Scientific Reports.

The researchers examined six tank-style electronic cigarettes and found all the aerosols had metals that appeared to originate in the atomizers.

Further, they found the model with fewest metal parts in its atomizer had the fewest metals in its aerosol.

Of the 19 metals they screened, aluminium, calcium, chromium, copper, iron, lead, magnesium, nickel, silicon, tin and zinc were from components in the atomizing units.

“We found the concentrations of chromium, copper, lead, nickel, and zinc exceeded the proposed permissible exposure limit from the Occupational Safety and Health Administration,” Williams said.

Chromium, lead, and nickel are known as carcinogens. Prolonged exposure to chromium could cause gastrointestinal effects, nasal and lung cancer, respiratory irritation, and lung function impairment.

Prolonged exposure to lead could produce vomiting, diarrhoea, cardiovascular effects, and lung cancer.

Nickel inhalation could cause lung disease, damage to the nasal cavity, lung irritation, lung inflammation, hyperplasia in pulmonary cells and fibrosis.

“The presence of heavy metals, including some known carcinogens, in e-cigarette aerosols is concerning because with prolonged exposure they could cause adverse health effects,” said Prue Talbot, a professor of cell biology, who led the research team. (IANS)
