Ketamine testing services
Drug-checking services exist to reduce the risks associated with using unknown or unregulated substances. They allow people to anonymously submit small samples so specialists can analyse what’s actually in them, since street drugs often contain unexpected or harmful additives. These services don’t encourage drug use — instead, they provide clear, factual information so people can make safer decisions, avoid dangerous contaminants, and understand the real contents of what they might be taking. They also help health professionals and communities spot emerging drug trends and issue timely warnings to prevent harm.
Different types of drug testing services
1. WEDINOS (Free Postal Testing Service)
-
A national harm-reduction project run by Public Health Wales.
-
You can send a tiny sample through the post anonymously and they will chemically analyse it and publish the result on their website.
-
It’s completely free (you only need to cover the cost of postage) and anonymous.
2. The Loop / Bristol Drug Checking
-
In Bristol, The Loop and Bristol Drugs Project run a street-drug-checking service where people can submit samples to be analysed and get harm-reduction advice.
-
Services are free and anonymous, though not currently available every day — often monthly sessions or specific events.
3. Reagent & Test Strips Through Local Support Services
-
Certain local drug support services (like WithYou, CGL etc.) can provide reagent test kits or fentanyl/nitazene test strips for free or low cost if you ask them.
-
Reagent kits can identify some substances but don’t tell you purity or full composition like a lab test does.
⚠️ Important Notes
-
Drug checking services are about harm reduction — they do not mean using drugs is safe. Any illegal substance use carries risk.
-
Some services only publish results online under a reference number and do not contact you directly.
-
Sending drugs through the mail is technically illegal, but services like WEDINOS operate within harm-reduction frameworks in the UK.
