Approximately 143,000 young people aged 12 to 17 used inhalants in the past year while dealing with a condition like pneumonia, bronchitis, asthma, or sinusitis, according to a new study. The study determined that the rate of use was 4.4 percent among adolescents who had at least one of the aforementioned respiratory conditions, similar to the rate among adolescents overall (4.1 percent).
