Question to the Home Office:

To ask the Secretary of State for the Home Department, if she will make an assessment of the potential impact of the reclassification of ketamine as a class B drug on (a) the rate of its usage among (i) 16 to 59-year-olds and (ii) 16 to 24-year-olds, (b) the average street price of ketamine and (d) its illicit availability in each year since 2015.

My reply to my honourable friend's previous questions as to what assessment the Home Office had made of the potential impact of the reclassification of ketamine on these four matters confirmed that we had not carried out such an exercise and that the drivers of the availability, market price and prevalence of drugs are complex.

As to any future assessments, in January 2025 my predecessor asked the Advisory Council on the Misuse of Drugs to provide an updated assessment on the harms of ketamine, and I would expect its report to provide an holistic assessment of that drug.
