5 Test Strips



As featured in The Times, Cosmopolitan, Evening Standard, Daily Mail, Mumsnet, Telegraph, The Sun, and Metro; and used by UK universities, bars and police forces.

Check Your Drink (CYD) has pioneered an easy to use drug detection strip that tests for both GHB and Ketamine, the two most widely used drink spiking drugs.

Both the GHB test and the Ketamine test have been developed and validated for the detection of these drugs by two independent bodies; the Clinical Trials Laboratory Services (CTLS) and Homerton University Hospital in 2013. Each test has been tested against a large range of alcoholic and non-alcoholic beverages to check for false positives.

Each pack contains 10 test strips. Simply put a drop of your drink on to each of the two test areas on a strip, and if the pink area turns blue or the yellow area turns orange, then your drink has been compromised.

Bringing a CYD pack with you on a night out could help protect you and your friends from that risk.


Thousands of people have their drink spiked every year. Many incidents happen in clubs, at festivals or on holiday and go unreported due to embarrassment or memory loss. Some cases can lead to sexual assault or mugging. We can all help to protect ourselves from this danger.

What are some symptoms of being spiked?

had any or enough alcohol to feel that way.

hallucinations or blurred vision.

How else do I protect myself?

  • Try not to go out on your own and go with

family/friends – look out for each other!

what time you expect to be home.

  • If possible, make plans for your journey

home at the beginning of your evening.

  • Never leave your drinks unattended.
  • Don’t finish your drink if you think its spiked.
