Many products found in the home or workplace contain volatile substances that have mind-altering properties when inhaled. These products include spray paints, markers, glues, and cleaning fluids. People do not typically think of these products as drugs because they were never intended for that purpose. However, these products are sometimes abused in that way. They are especially abused by young children and adolescents. They are the only class of substance abused more by younger than by older teens.
