E-cigarette victims mainly youth, says recent report by one of national public health institutes in United States.

Axar.az reports citing AA that nearly 1,100 cases of lung injury, reported to Centers for Disease Control and Prevention (CDC) from 48 states and one U.S. territory, are linked to using e-cigarette, or vaping products, according to a recent report.

CDC's weekly public information report on Thursday also revealed that 18 deaths have been confirmed in 15 states as of Oct. 1.

All patients have reported a history of using e-cigarette products, tetrahydrocannabinol (THC)-containing ones in particular, which, according to the latest national and regional findings play a key role in the outbreak.

CDC reported that approximately 70% of patients are male and overwhelmingly under 35 years old.

"Users may not know what is in their e-cigarette or e-liquid solutions. Many of the products and substances can be modified by suppliers or users," said CDC and recommended "refraining from using e-cigarette, or vaping, products, particularly those containing THC".
