INHALANTS

Found in: Solvents such as paint thinner, glue and gas, as well as some paints.

Source: The lab.

Legal code: Legal. But even though these substances are legal for their manufactured use, they are not intended for inhaling and are extremely toxic.

History: As solvent compounds became available in household products, people began experimenting with sniffing them. Gasoline inhalation became a problem with the introduction of the automobile in the early twentieth century, and glue sniffing became a problem in the 1950s.

Effects: The effects are similar to those for alcohol and nitrous oxide--instant stimulation, then drowsiness and sedation. Perceptual distortions and hallucinations have also been reported. A mild hangover-like feeling (headaches, poor concentration, possible nausea) may last for about 24 hours.

Risks: Even one-time use can lead to overdose and death from lack of oxygen, or "sudden sniffing death" (thought to be a result of cardiac arrest). Suffocation is a risk typically seen among inhalant users who use bags over their heads while sniffing to prolong the high; they may end up choking on vomit. Accidents while inhaling are very frequent, due to loss of motor control. Many solvents are flammable so there is also a risk of serious burns.

Inhaling solvents can also lead to nausea, nosebleeds, involuntary passing of urine and feces, dizziness, breathing difficulty and heart palpitations. Long-term risks include irreversible brain damage and nervous system damage.

Do not combine with: Anything else that makes you sleepy (i.e., alcohol, opiates, sedatives and cold medicines).

Addiction rating: High.
