Electronic cigarettes may cause, worsen respiratory diseases, among youth

Electronic cigarette “vapors” are made of small particles containing chemicals that may cause or worsen acute respiratory diseases, including asthma and bronchitis, among youth, according to a new study. Researchers examined particles emitted by e-cigarettes, an alternative nicotine delivery device, to understand what a user inhales and how these particles may affect the teen user’s lungs. In a cellular model, the study found some e-cigarette emissions cause acute toxicity, or lung damage, similar to that caused by conventional tobacco smoke.
