Nitazenes — read this one
Forget the fancy name. It's heroin's big brother — made in a lab, and hundreds of times stronger.
You've probably heard someone say "there's nitazenes in it" and switched off. Fair enough — it sounds like something off a chemistry exam. So here it is in plain English, because this is the thing killing people in Scotland right now, and people who only do coke are the ones it catches off guard.
Heard "there's fent in it"?
In Scotland, "fentanyl" gets used as a street name for all of these new lab opioids. If someone tells you there's fent going about, it's usually a nitazene.
Why it's the coke user it kills
Somebody who's been on heroin for years has a body that's used to opioids. If you only do coke, your body has none of that. Zero tolerance. So a trace that a heroin user might survive can switch you off completely — breathing and all. That's why this is on a cocaine site, and why it matters more to you, not less.
How it ends up in your night
In the coke itself
Scottish Drugs Forum warns it may be in cocaine here, and it's already been found in cocaine elsewhere in the UK. In Scotland it's mostly turning up in heroin, street Valium and fake oxy — but it's the same dealers, the same scales, the same bags. One dirty scale is all it takes, and a trace is all it needs.
The pills to come down
The blues. Street Valium. The wee pills to get you to sleep after a session. This is one of the main places nitazenes are turning up in Scotland. Coke up, street Valium down is exactly how people get a nitazene in them without ever touching heroin.
Whatever else is going round
Ket. Pills someone swears are MDMA. A vape that's "just weed." Across the UK, nitazenes have been found in all of them. If it's being passed about and nobody knows where it came from, nobody knows what's in it.
It doesn't look like a coke night going wrong
This is the bit that gets people killed. Everyone's watching for the coke signs. A nitazene looks like the opposite.
Coke going wrong
- Wired, can't sit still
- Heart racing, sweating
- Chest pain
- Paranoid, panicky
A nitazene going wrong
- Goes quiet. Gets sleepy. Nods off mid-sentence
- Or just drops — sudden collapse
- Pupils tiny — like pinpricks
- Snoring, gurgling or rattly breathing
- Lips, fingertips or skin going blue, grey or pale
- You can't wake them — shake them, shout their name, nothing
- Fitting
A coke comedown makes you tired. It doesn't make you snore, go blue, or stop waking up. If someone on a coke night goes quiet and you can't rouse them, that is not them "sleeping it off." It can drop someone within minutes. Treat it as an overdose — right now.
If it happens — do this
- Phone 999. Say they're not breathing right and you think it's an opioid. The ambulance is there to save a life, not get anyone lifted — in most cases paramedics won't tell the police.
- Give naloxone. Spray up the nose, or the jag into the outer thigh or upper arm — straight through their clothes is fine. Keep the used kit to hand to the paramedics.
- Not breathing properly after 2–3 minutes? Give another one. Nitazenes are that strong they can take more than one dose. Keep going, one at a time, until they come round or the ambulance gets there. That's why NHS inform says carry more than one kit.
- Recovery position, and don't leave them. Naloxone wears off in 20 to 40 minutes, and a nitazene can outlast it — they can come round, then go back under. Even if they wake up and say they're fine, they still need that ambulance.
Not breathing at all? The 999 call handler will talk you through CPR. Put them on speaker and do what they say.
What actually keeps you safe
Carry naloxone. Even if you only do coke.
Especially if you only do coke — and carry more than one. It's free from HaRRT or Renfrewshire ADP locally, every pharmacy in Scotland now holds it for emergencies, and Scottish Families will post a kit anywhere in Scotland in plain packaging. Where to get it →
Never use on your own.
With a nitazene, the person who saves you is whoever's in the room. If nobody's there, nobody gives the naloxone.
Don't take street pills to come down.
Blues, "Valium," sleepers off someone — nothing sold as a pill on the street is what it says on it. It's one of the most common places nitazenes are hiding.
Get it tested.
A fentanyl test strip won't pick up a nitazene — they need their own test. Postal testing through WEDINOS can find them, and Scotland's first drug-checking service opens at The Thistle in Glasgow on 5 October 2026, with Aberdeen and Dundee to follow. Ask your local service about nitazene test strips. WEDINOS →
It went from nothing to this in three years
Deaths in Scotland where nitazenes were implicated: 1 in 2022. 23 in 2023. 76 in 2024. 247 in 2025 — more than one in every five drug deaths in the country. In Renfrewshire, nitazenes were in 7 deaths in 2025, up from 3.
National Records of Scotland, September 2026 and September 2025. Nitazenes have only recently been tested for routinely at post-mortem, so the real number may be higher.
In Public Health Scotland's words, there is no safe way to take nitazenes. The only real move is not getting one in you — and having naloxone and a mate there for the times you can't know.
