South Korean government agencies found nicotine in several e-liquid products marketed as containing no nicotine during a recent testing sweep.
The findings highlight a significant public health risk for consumers seeking nicotine-free alternatives and suggest potential widespread violations of the Tobacco Business Act.
The Ministry of Food and Drug Safety and the Ministry of Economy and Finance conducted the testing on products sold through online platforms [1]. Authorities seized 105 e-liquid products that were marketed as “no nicotine” for analysis [1].
Of the products tested, nicotine was detected in 13 items [1]. Additionally, investigators found 6-methyl nicotine, a chemical similar to nicotine, in 12 products [1].
The government agencies said that the tests were conducted to verify the accuracy of product claims and to protect public health [2]. The discovery of these substances in products labeled as nicotine-free suggests that some manufacturers may be misrepresenting their ingredients to bypass regulations.
Officials are now determining whether these products violate the Tobacco Business Act [2]. The presence of 6-methyl nicotine is particularly notable as it represents a nicotine-like chemical that may have been used to evade standard nicotine detection tests.
This investigation focuses on online sales platforms where these “무니코틴” (no-nicotine) products were offered to the public [2]. The government has not yet announced specific penalties for the manufacturers involved, but the results provide a basis for further legal action under existing tobacco laws [2].
“Nicotine was detected in 13 items marketed as nicotine-free.”
The detection of 6-methyl nicotine suggests a deliberate attempt by some manufacturers to use chemical analogues to bypass regulatory screenings while still providing a nicotine-like effect. This creates a regulatory gap where 'nicotine-free' labels may be technically true regarding pure nicotine but deceptive regarding the presence of addictive chemical substitutes, potentially exposing non-smokers or youth to addictive substances.
