A data-led briefing on the latest NDTMS figures — covering who is in treatment, which substances are driving referrals, what professionals need to know, and how parents can spot the early warning signs.
Each year, England's National Drug Treatment Monitoring System (NDTMS) publishes data on how many children and young people are accessing substance misuse treatment services. The 2024/25 data — covering April 2024 to March 2025 — shows the highest number of young people in treatment for several years, and contains important information for parents, teachers and professionals working with young people.
It is worth emphasising what treatment data does and does not tell us. These figures represent young people in contact with services — a figure that depends as much on service capacity, referral routes and awareness as it does on the actual prevalence of use. The true number of young people experiencing problematic substance use is almost certainly significantly higher.[1]
The 13% year-on-year rise to 16,212 is the largest single-year increase recorded in recent data and brings treatment numbers back toward levels not seen since before the 2010s. NDTMS analysts note that this reflects both genuine increases in need and improvements in referral practice and service capacity following a period of under-resourcing.[1]
Cannabis remains by far the most common primary substance among young people entering treatment in England, accounting for the majority of referrals year on year. Alcohol is the second most common primary substance, with alcohol-related referrals remaining a significant proportion of the young people's treatment caseload. Other substances recorded include Class A drugs, volatile substances, and — increasingly — novel psychoactive substances including nitrous oxide.[1]
Cannabis is the primary substance for the majority of young people in treatment. Modern high-potency cannabis (often called 'skunk' or 'loud') carries significantly higher risks of dependence and mental health harm than lower-potency strains, and the average age of first use continues to fall. Young people presenting with cannabis-related problems frequently have co-occurring mental health needs, ADHD or trauma histories that require a whole-person treatment approach.
Understanding referral routes is important for professionals, as it highlights where identification is happening — and where gaps remain. Referral sources for young people's substance misuse treatment typically include:
Schools remain an underutilised referral source relative to their reach. A young person in school five days a week is observable in a way that no other professional has access to — and early identification through education has been shown to lead to better treatment outcomes.[2]
Under Keeping Children Safe in Education 2024, substance misuse is identified as a safeguarding concern where it places a child at risk of significant harm.[3] This includes situations where a young person's substance use is being exploited by others (such as county lines operations), where use is linked to self-harm or mental health crisis, or where the home environment involves parental substance misuse that affects the child.
Schools should have a clear drug and alcohol policy, an identified lead for substance misuse concerns, and a pathway for referral to local young people's drug and alcohol services. The DSL should be made aware of any pupil for whom substance misuse is a concern — even where it does not immediately meet the threshold for a Section 47 enquiry.
