If you’re here because last night doesn’t add up — missing hours, a level of drunkenness that made no sense, waking up somewhere you didn’t expect — take a breath. Whatever happened, it is not your fault, and there are concrete steps you can take right now. This guide walks you through the warning signs of being roofied, what next-day symptoms look like, how long the most common substances stay detectable, and exactly what to do next.
TL;DR: Sudden dizziness, disproportionate drunkenness and a memory blackout within 15–30 minutes of a drink are the classic signs of spiking; next-day clues include memory gaps and a crushing “hangover” that doesn’t match what you drank. GHB — one of the substances most drink spiking tests focus on — is detectable in blood for up to about 6 hours and in urine for up to about 12 hours, so seek medical care fast. Call 911 in an emergency, and reach the RAINN National Sexual Assault Hotline at 800.656.HOPE (4673) for free, confidential support.
Being roofied means someone has put a substance into your drink without your knowledge or consent. Despite the nickname — from “roofies,” slang for Rohypnol — most spiking today involves GHB, ketamine or benzodiazepines, which are typically colorless and tasteless, so you usually can’t see, smell or taste that anything is wrong.
Spiking is also far more common than many people realize. Police in England and Wales received 6,732 reports of spiking in the year ending April 2023, and in a December 2022 YouGov survey, 10% of women and 5% of men said they had been spiked at some point (UK Government spiking factsheet). Around 74% of reported victims are women — but anyone can be targeted.
How Do I Know If I Was Roofied? Warning Signs While You’re Out
Spiking symptoms usually begin within 15–30 minutes of drinking and feel wrong in a way ordinary alcohol doesn’t. Watch for:
- Sudden dizziness or drowsiness that comes out of nowhere
- Disproportionate drunkenness — you feel far more impaired than one or two drinks could explain
- Loss of motor control — trouble standing, walking or getting words out
- Nausea or blurred vision
- A blackout closing in — the night starts skipping like a scratched record
If your body suddenly feels wrong, act on it: tell a friend, tell staff, and don’t leave alone. Sometimes the drink itself gives a hint first — unexplained fizzing, cloudiness or sinking ice. We cover those in 5 signs your drink was spiked.
Signs You Were Roofied: Next-Day Symptoms
Many people only start asking “was I roofied?” the morning after. Next-day signs include:
- Memory gaps or a full blackout — hours you cannot reconstruct, even with help from friends
- Waking up somewhere unexpected, or not remembering how you got home
- An extreme “hangover” — grogginess, headache, nausea — that doesn’t match how little you drank
- Feeling drugged rather than hungover: heavy limbs, confusion, slowed thinking well into the day
- Unease, anxiety or shame about the missing hours
One thing matters here: these symptoms are not proof that you were drugged — but they are absolutely a reason to act. You don’t need certainty to deserve help. If any part of the night worries you, treat it seriously and follow the steps below.
How Long Do Roofies Stay in Your System?
The window for detecting spiking drugs is short — for GHB, painfully short. The UK Advisory Council on the Misuse of Drugs states in its Drug Facilitated Sexual Assault report that GHB “is undetectable in urine after 12 hours,” and the EU Drugs Agency’s thematic paper on GHB likewise reports it becomes “undetectable in urine after approximately 12 hours.”
| Sample | GHB detection window |
|---|---|
| Blood | Up to about 6 hours |
| Urine | Up to about 12 hours |
If more time has passed, testing is not necessarily over: hair testing by a specialist laboratory can sometimes document a single exposure weeks later. Detection windows also differ between substances — our comparison of GHB, ketamine and scopolamine breaks them down.
The practical takeaway: if you suspect you were spiked, seek medical testing as soon as possible. Every hour counts for GHB.
What to Do Right Now: Step by Step
Whether it’s happening right now or you woke up with questions, here is the sequence that protects you best.
1. Stay with people you trust
Don’t leave alone, and don’t let anyone you don’t know well take you “somewhere safe” — predators often pose as helpers. If you’re by yourself, move to a well-lit, busy spot and say clearly to staff: “I think my drink was spiked. I need help.”
2. Alert staff or security
Bar and venue staff can call 911, keep you somewhere safe, preserve the drink for testing, and pay attention to who leaves. Be direct — they are trained for exactly this situation.
3. Call 911 or get to an ER
If you or a friend is unconscious, struggling to breathe or seizing, call 911 immediately. Otherwise, go to an emergency room even if symptoms seem mild: GHB in particular can cause serious complications, and doctors can monitor you and run a drug test while it can still detect something.
4. Don’t let fear of getting in trouble stop you
Many states have Good Samaritan or Medical Amnesty laws: if you’re underage and were drinking, you generally will not be charged for seeking medical help for yourself or someone else. Getting help always comes first.
5. Preserve evidence if you can
Keep the leftover drink — don’t pour it out. Hospital staff or police may be able to test it. A positive drink-test strip, the glass, even the clothes you wore can all support a report later. Try not to wash things until you’ve decided.
6. Report — now or later
You can file a police report the same night, or days later once you feel steadier; a medical record from the ER helps either way. If you’re not sure what you want to do yet, that’s okay — the RAINN National Sexual Assault Hotline at 800.656.HOPE (4673) can talk through your options confidentially, with no obligation to report anything.
How to Recover From Being Roofied
Physically, most spiking substances leave the body within hours to days. Rest, drink water, eat when you can, and get a medical check-up even if you feel better — a doctor can rule out anything that needs attention.
Emotionally, the aftermath is often harder than the hangover. Self-doubt is extremely common: “Maybe I just drank too much. Maybe I’m overreacting.” You are not overreacting, and you did nothing wrong — someone else made a choice to drug you. You are also not alone: in a CDC-authored study of alcohol- and drug-involved sexual violence, 29.7% of female and 32.4% of male victims reported that they had been given a substance without their consent (Basile et al., 2021).

Preventing It Next Time — For You and Your Friends
None of this is about restricting your life — it’s about stacking the odds back in your favor. Roughly 80% of spiking incidents happen in public places like bars, clubs and festivals, so that’s where a few habits matter most:
- Use the buddy system. Arrive together, check in during the night, leave together. Agree that nobody gets left behind, ever.
- Keep your drink in sight. Order at the bar, watch it being made, and don’t drink from a glass that was out of view.
- Test before you drink. Symptoms only appear after a substance is already in your body. A DrinkCheck strip checks your drink in about 15 seconds and detects GHB, ketamine and more — before the first sip, not after.
If you run a bar or venue, stocking test strips protects your guests and is increasingly a compliance question too — California already requires many bars to offer drink-testing devices under AB-1013, and our wholesale program supplies venues directly.
