Scientists Warn Against Breathing in Secondhand Vape ‘Smoke’
A new study reveals secondhand vape aerosols contain harmful particles that can damage lung tissues, especially for those with pre-existing conditions.Summary
Researchers at the University of California Riverside have found that secondhand e-cigarette vapor, often referred to as ‘smoke,’ poses a risk to respiratory health. The study demonstrates that aged vape aerosols contain fine particles with metals and reactive compounds that combine to produce harmful radical particles. These particles, particularly ultrafine ones, can penetrate deep into the lungs and damage tissue. Experiments showed that aged aerosols created radicals, with ultrafine particles producing significantly more than larger particles. Individuals with conditions like asthma or COPD may be especially vulnerable. The researchers emphasize the need for further investigation in real-world settings and with commercially available e-liquids, as the current study used controlled laboratory conditions and a simplified vape fluid.
