The U.S. Centers for Disease Control and prevention has conducted a new study on the wave of lung injury related to electronic cigarettes that began last year.
These injuries affected more than 2800 people across the country. The study, published in the Journal of the American Medical Association Pediatrics, showed that young people were particularly hard hit.
Only 19% of the population over 12 years old are under 24 years old, but they account for more than half of the reported lung damage associated with e-cigarettes.
Adolescents are almost four times more likely to have a history of ADHD than normal people. They are also more likely to get e-cigarettes from informal sources such as friends, family and distributors.
