The misuse of solvents and volatile substances is a public health issue regulated under the Psychoactive Substances Act of 2016, which criminalizes the supply and import of "new psychoactive substances", including volatile solvents and glue, for consumption. However, the act does not explicitly mention glue sniffing as an illegal act.
Therefore, while glue sniffing may not be explicitly prohibited, engaging in this practice, especially in public or in a way that causes inconvenience or harm to others, can lead to legal consequences and be considered an offense.
