Inhalants are certainly addictive.  Users report that they continue to sniff the substances over and over because they enjoy the feeling of being high.  Because the “high” only lasts maybe 15 to 20 seconds, they tend to continue to use repeatedly despite the dangers to the body and brain. However, many users, especially teenagers, aren’t even aware of the dangers of huffing.  They think that a little sniffing isn’t a big deal, thinking they’ll be alright. However, medical experts state that inhalants can cause damage to many organs, including the brain, heart, liver, kidneys, and more. Inhalants are known to depress the central nervous system, but if too much inhaling is done, the user runs the risk of overdosing.In fact, some of the chemicals can cause seizures, coma, and death within minutes because they are highly concentrated. The number of chemicals hitting the body all at once, can stop the heart within a minute or two, causing sudden sniffing death.
