London nightclubs are warning revellers about dangerous blue and green pills being sold as ecstasy after two people died last month having taken the substance.
Police continue to investigate the “sudden” deaths of a 28-year-old man and a 20-year-old woman who died in Ealing on Bank Holiday Monday, May 26.
The pair allegedly passed away after taking an “illicit substance in the form of a green pill,” the Met Police said.
No arrests have been made and officers are working with the health service and councils to issue advice to Londoners.
Drug checking charity The Loop warned that the pills contained nitazenes, synthetic opioids which can be 50 to 500 times stronger than heroin.

2 deaths last weekend in London were from pills confirmed as #nitazenes & similar to pills tested by The Loop.
They looked like oxys BUT it is not known what they were bought as.
Take care whatever pills you take.

London venues have been warning people to look after themselves and to speak to a member of staff immediately if anyone in the crowd suddenly feels unwell this weekend.
The Cause, one of east London’s most loved clubs, shared a photo of two pills marked with the number 80 on their Instagram, strongly advising partygoers not to engage with it and to warn their friends.
The venue reminded its followers that it has a zero tolerance policy towards drugs.
In a separate warning, London clubbing icons’ Fabric, wrote: “We’ve been informed of a dangerous batch of light green pills currently in circulation with ‘80’ on one side and possibly ‘OP’ on the other.”
The club explained that testing has found that the drug contains a “potent synthetic opioid” as well as traces of ketamine and MDMA.
Fabric told club goers to look after themselves and each other and to speak to a member of staff if they feel unwell at the venue.
Earlier in the week Ealing Council also issued a warning about the pills, explaining two people who took the unidentified pills had died.
The council explained they had been together and were in Southall.
Ealing told residents: “Please remember, there is no way of knowing what is in any pill or drug that is bought illegally, or how your body will react.
“If you, or anyone you are with, starts to feel unwell after taking any pill or drug, go to your nearest Accident and Emergency department or call 999.
“Always seek medical attention and do not try to sleep it off or drink lots of water.”
