    Scale of Parental Substance Misuse in the UK

    Alcohol misuse

    • 2.6 million children in the UK – living with a parent who drinks to hazardous levels, an estimate widely cited by Nacoa and the NSPCC as of 2026.
    • 200,000 children in England – living with an alcohol-dependent parent, according to The Children’s Society.
    • 120,552 alcohol-dependent adults living with children in England – estimated by the government’s CADeP evaluation (based on 2018–19 data), with approximately 21% in treatment at that time, leaving an unmet need of 79%.
    • 1 in 3 children aged 10 to 17 – experience negative consequences as a result of a parent’s drinking, according to The Children’s Society.
    • 1 in 5 children in the UK – affected by parental drinking, per Nacoa’s 2026 estimate.
    • 22% of children – live with a hazardous drinker, and 30% live with at least one adult binge drinker, according to Greater Manchester SCP data.
    • 73,250 children in England – identified via Child in Need assessments as having a parent who misused alcohol between April 2024 and March 2025, the latest full-year figure available. Courts frequently rely on hair alcohol testing to provide an objective measure of a parent’s drinking over time.

    Drug misuse

    • 478,000 children in the UK – living with an alcohol or drug dependent parent, equating to a rate of 40 per 1,000 children, per the government’s CADeP evaluation.
    • Between 200,000 and 300,000 children in England and Wales – estimated to have one or both parents with serious drug problems, according to the ACMD Hidden Harm report.
    • 4% of children in England – estimated to be living with a parent using alcohol or drugs in 2019–20 (Muir et al., 2022), equivalent to roughly 478,000 children.
    • Parental drug use a factor in 13% of Child in Need cases – and parental alcohol use in 14% of cases, per DfE 2023 statistics. In family court proceedings, hair strand drug testing is often used to establish whether a parent has been using drugs over a period of months.

    Children in Substance Misuse Treatment

    National treatment numbers

    • 16,212 children aged 17 and under – in alcohol and drug treatment between April 2024 and March 2025, a 13% rise from 14,352 in 2023–24, per the Office for Health Improvement and Disparities (OHID).
    • 34% lower than the 2008–09 peak of 24,494 – despite the recent rise, the number in treatment remains substantially below historic highs.
    • 85% of children – successfully completed treatment programmes in 2024–25.

    • Alcohol a factor in at least 33% of child protection cases – based on research cited in the Greater Manchester SCP multi-agency guidance.
    • At least one of alcohol or drug misuse present in 47% of serious case reviews – with alcohol recorded in 37% and drugs in 38%, per the DfE analysis cited by Government Events (2021).
    • 39% of children added to Scotland’s child protection register in 2023–24 – had parental substance use listed as a concern, making it the third most common risk factor after domestic abuse (45%) and neglect (42%).

    • 37,000 contacts received by Nacoa in 2025 – from people affected by a parent’s drinking, with high levels of relationship breakdown and parental death among presenting concerns.
    • 60% rise in calls to Nacoa since 2019 – with young people increasingly reaching out, particularly during and after the Covid pandemic.
    • 440 Childline counselling sessions – delivered in 2023–24 with children and young people worried about their parent’s substance misuse.
    • Nacoa estimates 1 in 5 children in the UK – are affected by parental drinking, equating to roughly 3 million children based on a study of 4,000 respondents.

    Impact on Children and Families

    Mental health and behaviour

    • 6 times more likely to witness domestic violence – children of alcoholics, compared to peers, per Nacoa research.
    • 5 times more likely to develop an eating problem – for children growing up with a parent with alcohol dependence.
    • 3 times more likely to consider suicide – children of problem drinkers compared to those without parental alcohol misuse.
    • Twice as likely to have difficulties at school – children living with a parent’s alcohol problems.
    • Twice as likely to develop alcoholism or addiction themselves – reflecting intergenerational risk documented in Nacoa research.
    • 3.6% of UK children – estimated to be living in households where all three ‘trigger trio’ factors (parental domestic abuse, mental ill health and substance misuse) are present to a moderate or severe extent (UCL/Children’s Commissioner analysis).
    • 0.9% of all children in England – estimated to live in a household where a parent faces all three trigger trio issues at a severe level, equivalent to approximately 100,000 children.

    Educational and social outcomes

    • Twice as likely to be in trouble with the police – children of alcoholics, and twice as likely to experience difficulties at school.
    • A child twice as likely to become looked after – if a parent has an alcohol or substance misuse issue, per the Lancashire ‘trigger trio’ analysis.
    • Intergenerational patterns – if parental substance use is not addressed, Public Health England identifies risks of intergenerational substance use, unemployment, offending, domestic abuse, and child abuse and neglect.
    • 52% of children in FDAC cases reunited with primary carers – compared to 12.5% in standard care proceedings, demonstrating the value of specialist intervention (Foundations/Justice Innovation, 2024).
    • 33.6% of FDAC parents ceased misusing drugs or alcohol – by the end of care proceedings, compared to 8.1% in standard proceedings.

    Foetal Alcohol Spectrum Disorder (FASD)

    • At least 3.6% of the UK population – affected by FASD, per studies by McCarthy et al. (2021) and McQuire et al. (2019), meaning roughly 1 child in every school classroom.
    • 3.2% of babies born in the UK – estimated to be affected by FASD, which is three to four times the rate of autism, per SIGN guidelines (2023).
    • Up to 6% of children in the Avon Longitudinal Study – showed symptoms consistent with FASD in University of Bristol research (McQuire, 2024).
    • 42% of meconium samples in a Glasgow study – showed evidence of maternal alcohol consumption during pregnancy, with 15% of those pregnancies exposed to very high levels.
    • FAS incidence estimated at 3.4 per 100,000 live births – in a UK surveillance study (Burleigh et al., 2023, ADC), though researchers note FAS is significantly under-diagnosed.
    • Approximately 900 babies born in the north-east of England each year – with foetal alcohol spectrum disorder, according to Dr Sarah Mills, Newcastle, with concerns raised about elevated rates following pandemic lockdowns.
    • FASD remains significantly under-researched in the UK – with the University of Bristol team noting an absence of national linked data, leading to a 2024 database initiative to improve surveillance.

    Neonatal Abstinence Syndrome (NAS)

    • 1,363 babies born with NAS in Scotland over seven years – between 2017 and 2024, based on Freedom of Information data secured by the Scottish Liberal Democrats.
    • More than 200 babies born with NAS each year in Scotland – as of 2025–26, with NHS Lothian (692 cumulative cases), NHS Grampian (209) and NHS Greater Glasgow and Clyde (201) reporting the highest totals.
    • 1,087 babies in England affected by maternal drug use in 2014–15 – the most recent NHS England NAS figure available at national level, indicating the issue predates current reporting.
    • 75 babies in Wales – affected by drugs and alcohol in 2015–16, per NHS Wales data.
    • NAS symptoms – include uncontrollable trembling, high-pitched crying, blotchy skin and hyperactivity, with almost every drug crossing the placenta to the foetus’s bloodstream.

    Scotland: Drug Deaths and Children

    • 1,017 drug misuse deaths registered in Scotland in 2024 – a 13% decrease (155 deaths) from 2023, and the lowest figure since 2017 (National Records of Scotland).
    • 1,172 drug-related deaths in Scotland in 2023 – a 12% increase on 2022, the latest annual report showing the continued scale of the crisis.
    • More than 600 children lost a parent to drug-related deaths in just one year – Scotland’s Public Health Scotland report covering 2019–2020 revealed the scale of parental drug death on families.
    • 16% of those who died from drug-related deaths in Edinburgh in 2024 – were known to have children under the age of 16 at time of death (NHS Lothian annual report).
    • More than half of those who died – lived in the most deprived parts of Scotland, and two-thirds were in contact with a service that could have helped.
    • Opiates/opioids implicated in 80% of drug misuse deaths in Scotland in 2024 – followed by benzodiazepines (56%) and cocaine (47%), per National Records of Scotland.
    • 39% of children on Scotland’s child protection register in 2023–24 – had parental substance use recorded as a concern at their child protection planning meeting.

    Economic and Social Cost

    • £27.44 billion total annual cost of alcohol harm to England – the most comprehensive recent estimate, from the Institute of Alcohol Studies (2024), up 40% since 2003.
    • £4.91 billion cost to the NHS and healthcare system – from alcohol harm in England annually, enough to pay for the salaries of almost half of England’s nurses.
    • £2.89 billion cost to social services – attributable to alcohol in England each year, including £2,705 million for child social services alone.
    • £14.58 billion cost of alcohol to crime and disorder – the single largest component of the total annual harm cost.
    • £37 million spent by the NHS on addiction treatment – for wholly drug-related hospital admissions annually; effective community drug treatment cuts drug-related hospital attendances by 31%.
    • £310 million in targeted grants – provided by the Department of Health and Social Care in 2025–26 to improve drug and alcohol treatment services and wider recovery support.
    • Average alcohol harm cost of £485 per person per year – across the England population, reflecting the external cost imposed on society.

    Family Drug and Alcohol Courts (FDACs)

    • 210 open FDAC cases on 1 April 2024 – a 162% increase since January 2021 when current data collection began, reflecting rapid expansion of the model.
    • 53 new cases admitted to FDAC – in Q2 2024 (April to June), involving 88 children, with an average parental age of 36 and average child age of 6.
    • 80% of FDAC parents had ongoing substance use issues – at referral; 9% were using only alcohol and 15% drugs only.
    • 52% of children in FDAC cases reunified with their primary carer – at the end of care proceedings, versus 12.5% in standard care proceedings.
    • 33.6% of FDAC parents ceased misusing substances – by the end of proceedings, compared to 8.1% in standard proceedings.
    • 35% of FDAC mothers stopped misusing and reunited with their children – compared to 19% in standard comparison group, in the original FDAC evaluation.
    • Government savings – FDAC generates significant savings to health, education and social care systems through higher rates of family reunification and reduced re-entry into care.

    2026 Outlook

    • £310 million in government grants for 2025–26 – committed by DHSC for drug and alcohol treatment and recovery, explicitly including reducing the adverse childhood experience of parental substance misuse.
    • 13% annual rise in children entering treatment – in 2024–25, a trend expected to continue as service capacity is rebuilt following years of austerity cuts.
    • Ketamine now in the top 4 substances – reported by children in treatment, with 1,465 cases in 2024–25 versus 512 in 2021–22; specialists forecast continued growth given its prevalence in the teenage market.
    • Elevated FASD birth cohort from pandemic pregnancies – entering primary school from 2025 onwards; clinicians estimate a higher proportion of FASD among children born during 2020–21 lockdowns when alcohol consumption rose sharply.
    • More than 200 babies born with NAS each year in Scotland – with no sign of reduction, driving calls for perinatal substance misuse services to be better integrated into maternity pathways.
    • 73,250 children identified with a parent misusing alcohol – in 2024–25 Child in Need assessments; with adult treatment numbers at a record high, this figure is unlikely to fall in 2025–26.
    • FDAC expansion target – justice and family law reformers are pushing for FDAC to cover all 152 local authority areas in England; currently only 13 operate the model, meaning the vast majority of families in care proceedings lack access to this evidence-based intervention.
    • NHS 10-Year Plan (2025) – commits to preventing the number of 11 to 15 year-olds who vape or use substances from rising, and expanding early intervention for young people affected by parental substance misuse.
