Drink Spiking
Understanding the risks of drink spiking, recognising the symptoms, and knowing what to do if you suspect a young person's drink has been tampered with.
Drink Spiking is the act of adding alcohol or drugs to someone's drink without their knowledge, which can leave a young person vulnerable to harm, assault, or serious illness.
What is this?
Drink spiking occurs when alcohol or another substance — such as a sedative, tranquilliser, or drug such as GHB — is added to someone's drink without their knowledge. It is most often associated with night-time venues, parties, and festivals, but can occur in any social setting. Victims are typically targeted to facilitate sexual assault, robbery, or other exploitation. Drink spiking is a criminal offence. Young people aged 14 and over, particularly those who are beginning to socialise independently, are at increased risk.
How it works
Spiking can involve adding additional alcohol to a soft drink, or introducing a drug such as Rohypnol, GHB, ketamine, or benzodiazepines. These substances are often colourless and odourless, making detection difficult. Effects can include sudden dizziness, confusion, nausea, loss of inhibition, memory loss, and loss of consciousness. The onset of symptoms can be rapid — within 15 to 30 minutes of ingestion. In recent years, needle spiking — injecting a substance through the skin — has also been reported at venues.
Warning signs
In your child's behaviour
- • Unexpected confusion or disorientation that seems out of proportion to any alcohol consumed
- • Feeling unusually intoxicated after consuming only one or two drinks
- • Waking with gaps in memory, unexplained symptoms, or no recollection of events
Prevention steps
Discuss drink safety before a young person socialises independently
Before your teenager attends parties or venues, have a direct conversation about drink spiking. Cover the basic rules: never leave a drink unattended, never accept a drink from a stranger or someone you do not fully trust, and never drink from a bottle or glass you did not see poured. Make sure they know what to do if they or a friend feel unwell.
Establish a safety plan
Agree on a buddy system — going out with a trusted friend and looking out for each other. Set up a code word or signal that means 'I need help' or 'come and get me'. Make it clear that they can call you at any time, even late at night, without fear of getting into trouble, if they or a friend are in danger.
Know about spiking detection products
Nail varnishes and test strips that can detect some spiking drugs are available and may offer reassurance, though no product detects all substances. These are not a substitute for the basic precautions above but can be part of a young person's personal safety toolkit.
What to do if it happens
- 1If a young person shows sudden signs of extreme intoxication, confusion, or loss of consciousness, treat it as a medical emergency and call 999. Do not leave them alone.
- 2Inform venue staff immediately. Stay with the affected person and ensure they are in a safe position (recovery position if unconscious). Do not give them water or food until medical help has arrived.
- 3Encourage the young person to report to the police as soon as they are able — ideally by calling 101 or attending a police station. Medical evidence collected soon after spiking is important for any investigation. Support is available from Rape Crisis (rapecrisis.org.uk) and local Sexual Assault Referral Centres (SARCs) regardless of whether a crime is reported.

Myths & facts
Myth: Drink spiking is something that only happens to girls and young women, so boys and young men do not really need to worry about it.
Fact: Spiking can affect anyone, regardless of gender. Boys and young men are also spiked, so the same precautions - never leaving a drink unattended, watching it being poured, and looking out for friends - apply to everyone, not just girls.
Myth: Only alcoholic drinks can be spiked, so soft drinks, energy drinks, or a glass of water are always safe.
Fact: Any drink can be spiked, including non-alcoholic ones. A substance used to spike a drink can be added to a soft drink or water just as easily as to alcohol, so the same care - not leaving it unattended, watching it poured - applies to every drink a young person has at a party or venue.
Myth: Spiking someone's drink as a joke or a prank is not really taken seriously by the law, as long as nothing else happens afterwards.
Fact: Spiking is a criminal offence in the UK in its own right. Administering a substance to someone without their knowledge or consent is against the law, and being done 'as a joke' is not a defence that makes it acceptable or lawful.
Age by age
- 14-16
Young teenagers starting to attend parties or venues benefit from concrete, rehearsed rules rather than general warnings: only accept a drink they watched being poured, keep an eye on friends' drinks too, and know they can call you at any hour, no questions asked, if something feels wrong.
- 17-plus
Older teenagers socialising more independently in pubs, clubs, or at festivals should carry a charged phone and know how to get home safely without relying on a stranger, and understand that reporting a suspected spiking promptly - even without certainty - helps preserve medical evidence and get them the right care quickly.
