As the Deputy will be aware, the legislation governing the conduct of preliminary road side drug tests is the Road Traffic Act 2016, which falls under the remit of my colleague, the Minister for Transport, Tourism and Sport, Mr. Shane Ross, T.D.. I have been advised that the following drugs are provided for under this legislation: THC (Cannabis), Cocaine, Opiates and Benzodiazepines.
While the enforcement of road traffic legislation is an operational matter for An Garda Síochána, I have requested information from the Garda authorities in relation to the types of drugs detected during mandatory intoxicant testing checkpoints in 2017 and I will be in contact with the Deputy directly on receipt of a Garda report.
