US researchers have found that electronic cigarettes, often targeted at youth and pregnant women, produce a stress response in brain stem cells.
Present throughout life, stem cells become specialised cells with more specific functions, such as brain cells, blood cells, or bone.
“Although originally introduced as safer, ECs, such as Vuse and JUUL, are not harmless,” said Atena Zahedi from the University of California.
“Even short-term exposure can stress cells in a manner that may lead, with chronic use, to cell death or disease. Our observations are likely to pertain to any product containing nicotine,” Zahedi said.
