Practice otherwise known as huffing, in which people inhale hydrocarbons to get high, reemerges
Chroming, aka huffing, isn't a new phenomenon, but the practice -- which involves inhaling hydrocarbons to get high, often via common household items like nail polish, permanent markers, and paint thinner -- is reemerging, thanks partly to social media. Medical experts, in turn, are getting concerned. "People have been inhaling fumes for centuries," pediatrician Dr. Betty Choi tells CNN, noting that this type of inhalant abuse reached its peak in the '90s. "But in recent years, experimentation rates among teens have risen again."
