Inhalants: Inhalants are a diverse group of substances that are sniffed, snorted, huffed, or placed in bags and inhaled to produce intoxication. Common household products such as glue, lighter fluid, cleaning fluids, and paint are the most abused inhalants. Inhalant users experience headache, nausea, slurred speech and loss of motor coordination.

About one in five kids report having used inhalants by the eighth grade. They sniff or "huff" ordinary household products like nail polish remover, cleaning fluid, gasoline, and spray paint.
