Solvent abuse is the deliberate inhalation of volatile chemicals for the purpose of getting intoxicated or ‘high’. The fumes and gases inhaled are found in everyday products such as cigarette lighter refills and aerosols. Some volatile substances are covered by the 2016 Psychoactive Substances Act, and it’s illegal in England and Wales for anyone to sell glues, gases, solvents and aerosols to people, if they think they’re likely to be inhaling them to get high.
