I recently met Home Office Ministers to discuss the use of synthetic cathinones, often referred to as monkey dust, in Stoke-on-Trent. These substances cause significant harm to users and, indeed, communities. They are frequently sold via the dark web and imported through the post. Can the Secretary of State provide an update on her work with the National Crime Agency and Royal Mail to detect illicit substances using technology, and advise whether existing opioid detection methods can be adapted or applied to synthetic cathinones?
