Even though solvent glue is normally a legal product, there is a case where a court has ruled that supplying glue to children is illegal. Khaliq v HM Advocate was a Scottish criminal case decided by the High Court of Justiciary on appeal, in which it was decided that it was an offence at common law to supply glue sniffing materials that were otherwise legal in the knowledge that they would be used recreationally by children. Two shopkeepers in Glasgow were arrested and charged with supplying to children "glue-sniffing kits" consisting of a quantity of petroleum-based glue in a plastic bag. They argued there was nothing illegal about the items that they had supplied. On appeal, the High Court took the view that, even though glue and plastic bags might be perfectly legal, everyday items, the two shopkeepers knew perfectly well that the children were going to use the articles as inhalants and the charge on the indictment should stand. When the case came to trial at Glasgow High Court the two were sentenced to three years' imprisonment.
