A warning over super-strength drugs has been issued after “several” people partying at “multiple London venues” were hospitalised.
Bosses at Fabric nightclub in Farringdon said some revellers had “become very unwell and had seizures” last weekend.
While the cause of the incidents has not been established, it is believed they could be linked to “unusually strong” ecstasy pills or MDMA.
“We are aware of several hospitalisations across multiple London venues last weekend, where people have had seizures and become very unwell,” Fabric said in a statement.
“While the causes of individual incidents are not clear, it may be driven by unusually strong pills/ MDMA on the market.
“A typical heavy dose is around 200mg, but some of these pills are reported to contain over 300mg which creates a strong overdose risk.
“If in doubt, please don’t take it.”
Fabric has a welfare team which patrols the world-famous venue and can be contacted via WhatsApp during club nights.
London Ambulance Service (LAS) confirmed paramedics attended two drug-related incidents at Fabric on October 13.
But it could not confirm exactly what patients had taken.
A Metropolitan Police spokesman said: "There is no ‘safe’ way to take drugs. There is always a risk. Do not purchase illegal drugs."
Ahead of Glastonbury festival The Loop - a non-profit which tests drugs in circulation - urged revellers to be cautious after finding pills containing more than 300mg of MDMA at Manchester’s Parklife festival.
It said recent tests show the strength of ecstasy pills have risen back to pre-pandemic levels and warned this “could increase risk to users”, with young people who came of age during Covid “particularly at risk”.Adam Waugh, training coordinator of The Loop said: “The safest option is not to take pills. However, if someone is going to take them, it is safer to start with a quarter.”
