Many of these hydrocarbons are thin liquids. If you drank one of these hydrocarbons, it is likely some will slip down your windpipe and into your lungs (aspiration) rather than going down your food pipe (esophagus) and into your stomach. This can easily happen if you try to siphon gas out of a gas tank with a hose and your mouth.</p><p>Hydrocarbons may be inhaled intentionally for intoxication, especially by adolescents.
