Glue and gasoline (petrol) sniffing is also a problem in parts of Africa, especially with street children. In India and South Asia, three of the most widely abused inhalants are the Dendrite brand and other forms of contact adhesives and rubber cements manufactured in Kolkata, and toluenes in paint thinners. Genkem is a brand of glue which had become the generic name for all the glues used by glue-sniffing children in Africa before the manufacturer replaced n-hexane in its ingredients in 2000.
