Each week, Gareth breaks down what’s really in local substances.
Gwent
A sample purchased as Heroin contained no active substances.
Using samples like this can lead to a loss of tolerance and an
increased risk of overdose when using Opiates or Opioids again.

Britain
A substance purchased as ‘A Benzimidazole Opioid-(Nitazene)’
was analysed as containing Heroin, N-propionitrile chlorphine
(Cychlorphine) – a synthetic Opioid around the same potency
as Fentanyl or Nitazenes – and Medetomidine, an anaesthetic
not for human use and around 200 times stronger than Xylazine.
A sample purchased as Heroin in a white powder form was
analysed as containing 5,6-dichloro desmethylchlorphine,
another potent synthetic Opioid, and again Medetomidine.
Another sample purchased as Heroin in a white powder form
contained N-propionitrile chlorphine (Cychlorphine), which is
similar in potency to Fentanyl and Nitazenes.
A further sample purchased as Heroin was analysed as
containing Heroin and Medetomidine.
There is a high risk of overdose when using these substances.
Please use with others, carry Naloxone, and call an ambulance
if anyone suffers any adverse effects.
It is more important than ever to get your substances tested.
Testing through WEDINOS is free, anonymous, and can help
you make safer choices.
Testing Your Substances
These samples were tested by WEDINOS. You can test yours too!
Take old baggies or paraphernalia to a drug service; it could save your life.
