Drink spiking: signs, what to do, and how to check your drink

Call 999 or go to A&E if you think someone may have swallowed something harmful. If you are not sure whether what they swallowed is harmful, call NHS 111. Call 999 for collapse, unconsciousness, a seizure or serious breathing difficulty. A drink test must never delay care. This guide covers practical support, reporting and the limitations of retail screens without assuming that you should have prevented someone else's actions. Spiking is always the responsibility of the person who does it.

What is drink spiking?

Drink spiking means putting alcohol or another substance into someone's drink without their knowledge or consent. The concern is the lack of consent and potential harm, not whether a person was drinking alcohol already. GOV.UK: Spiking factsheet

Spiking can happen in different settings, including private gatherings as well as venues. Someone does not need to have left a drink unattended to deserve help. You also do not need to be certain that spiking occurred before telling someone that you feel unsafe or unexpectedly unwell.

A suspicious drink and a person who may have been exposed are different testing questions. A sticker used on a drink cannot assess the person's condition, identify every possible substance or establish what happened earlier. Safety and medical assessment come before trying to resolve that uncertainty.

What signs should make you seek help?

Sudden or unexpected illness, confusion, difficulty staying awake, loss of coordination or memory gaps can be reasons to suspect something is wrong. These signs are not specific enough to identify spiking or a particular substance. NHS: Poisoning; GOV.UK: Spiking factsheet

Do not compare symptoms with a drug-effects chart or assume someone is simply drunk. If their condition is unexpected, deteriorating or difficult to assess, involve medical services. Tell staff or a trusted person what has changed and stay with the affected person.

Call 999 if someone may have been poisoned, loses consciousness, has a seizure or has serious difficulty breathing. If you are unsure whether an exposure is harmful, NHS guidance directs you to call 111. Do not wait for a drink test, a particular symptom pattern or proof of an offence before seeking medical advice. NHS: Poisoning

What should you do immediately if you suspect spiking?

Stop drinking the suspected drink and get to a safer place with someone you trust. Call 999 or go to A&E if you may have swallowed something harmful. If you are not sure whether it is harmful, call NHS 111. NHS: Poisoning; GOV.UK: Spiking factsheet

Tell venue staff, a friend or security what you are worried about. Ask them to stay with you and help contact the appropriate service. Do not leave alone or with someone you do not trust, and do not drive. If there is an immediate threat, call 999.

If it is safe, keep the drink or its container and note the approximate time and place. Evidence may be useful later, but collecting it must not put you in danger or delay treatment. A positive retail screen is not a requirement for care or reporting. Your immediate wellbeing is the priority.

How can you help a friend who may have been spiked?

Stay with them, get help and explain what you have observed. Speak calmly, take the concern seriously and avoid blaming them for what they drank or where they were. NHS: Poisoning; GOV.UK: Spiking factsheet

If they are unconscious but breathing, follow emergency advice about the recovery position and keep checking their breathing. If they are unresponsive and not breathing normally, call 999 and follow the operator's instructions about CPR. Do not assume they can safely sleep it off.

For suspected poisoning, NHS guidance says not to make the person vomit or give them food or drink. Tell healthcare staff about any known medicines, alcohol or other exposure without guessing or withholding information. Do not attempt to identify the cause yourself while the person becomes more unwell. Call 999 for serious symptoms or suspected poisoning. NHS: Poisoning

Can you tell whether a drink is safe by its taste or colour?

No. Sensory checks are not a reliable way to establish that a drink has not been tampered with. Do not taste it to investigate a concern. GOV.UK: Spiking factsheet

Changes to a drink can be a reason to stop drinking it, but the absence of a change cannot prove safety. The same applies to an apparently reassuring home screen: every device has limits on what it checks and under which conditions.

If you have not consumed the drink, there is no benefit in taking a sip to see whether you develop symptoms. Move away from the concern and involve someone trusted or venue staff. If you have consumed it and are concerned about exposure, contact medical services rather than relying on its appearance or a test result.

What are the different types of testing?

A drink screen, a medical assessment and police forensic testing answer different questions. They should not be treated as interchangeable evidence. NHS: Poisoning; GOV.UK: Spiking factsheet

Ask the police about their testing arrangements promptly if you want to report. Do not assume a clinical sample will serve as a forensic sample, or that a negative result proves nothing happened. A concern still deserves attention and support.

What can SipSafe drink stickers check?

According to the supplied product facts, SipSafe screens for GHB, ketamine and flunitrazepam only. It does not cover every possible substance, added alcohol or every type of drink.

The product facts describe a reading in around one to three minutes, but the exact sampling, supported drink types and interpretation come from the leaflet. Do not improvise the method, compare it with another brand's chart or read outside the specified window.

A sticker is an optional limited screen, not protection against being spiked or a test of your body. Its use does not transfer responsibility to the person carrying it. If you suspect tampering, do not use a negative reading as a reason to finish the drink. Medical symptoms or exposure concerns take priority over any sticker result.

What should you do after a positive or negative drink screen?

Stop drinking a suspected drink regardless of the screen's result. A positive result needs to be taken seriously, but a negative result does not establish safety.

Keep the device and container if safe, note when you tested and explain the concern to staff or police. Do not attempt to identify a drug from a colour beyond the leaflet's stated interpretation. A retail result alone does not prove who added a substance or provide a complete forensic account.

If someone may have swallowed something harmful or is seriously unwell, call 999. If you are unsure whether an exposure is harmful, call NHS 111 for urgent advice. Care should not depend on whether the screen looked positive, negative or unclear, and an invalid reading should never be treated as reassuring. NHS: Poisoning

How quickly should you report suspected spiking?

Report promptly if you want police to investigate, because potential evidence and appropriate samples can be time-sensitive. There is no universal time window that applies to every substance and situation. GOV.UK: Spiking factsheet

Tell police when and where you think it happened, any symptoms, whether medical care was provided and whether the drink or container is available. A rough timeline is useful even if parts of the evening are unclear. You do not have to identify a substance yourself.

Do not conclude that reporting is pointless because time has passed or a test was negative. The police can explain what options remain. Use 999 for an immediate danger or emergency; otherwise use the police non-emergency reporting route. You can ask someone trusted to support you while making the report.

Is spiking illegal under current UK law?

Yes. Spiking is criminal behaviour. The Crime and Policing Act 2026 received Royal Assent on 29 April 2026 and includes a standalone harmful-substance offence covering spiking. GOV.UK: Spiking factsheet; GOV.UK: Crime and Policing Act 2026; GOV.UK: Crime and Policing Act: overarching factsheet

An Act receiving Royal Assent does not mean every provision necessarily starts on that date. The applicable law, commencement and jurisdiction are matters for police and legal services. You do not need to determine the offence or quote a section before reporting what happened.

The purpose of this guide is practical support, not a legal assessment of an individual case. Report a concern in your own words and ask what will happen next. The absence of a positive home test does not make the conduct acceptable, and deciding not to report does not remove your right to medical care and support.

What if sexual assault may have happened?

Seek medical and specialist support, even if you are uncertain about what happened or do not want to report to police. NHS sexual assault referral centres can provide care and help you consider options. NHS: Help after rape and sexual assault

Some care after assault is time-sensitive. A specialist service can discuss injuries, pregnancy prevention, sexual health and forensic choices without making you decide everything at once. You can ask a trusted person to help you contact a service or attend with you.

If you want evidence collected, NHS advice recommends seeking help promptly and, if possible, avoiding washing or changing clothes first. You can still seek help if you have already done either. Call 999 if you are in danger or seriously unwell. What happened was not your fault, whatever you wore, drank or remember.
