Many household and industrial products contain chemicals that, when inhaled, can cause intoxication. These products are referred to as volatile substances or solvents. Examples are toluene, butane and other volatile hydrocarbons that evaporate at room temperature.

Products that may contain solvents include aerosols (e.g. air fresheners, hair sprays and deodorants), some paints and paint thinners, petrol, some correction fluids, nail varnish removers, some glues and cigarette gas-lighter refills.

Physical co-ordination may be impaired. Users may feel light-headed, dizzy or drowsy. Altered perception may be experienced, ranging from visual distortion to auditory and visual hallucination.

Effects vary from user to user and according to the type and quantity of substance used.
