Clubbers who feared they had been drugged were tested by medics over the weekend as part of a new scheme aimed at cracking down on spiking incidents.
Customers at Warehouse Project who suspected they may have been drugged with GHB, GBL or Rohypnol were tested for the drugs during events at the superclub on Friday and Saturday.
None tested positive, but club boss Sacha Lord says staff will continue to test anyone who suspects they have been targeted from now on.
Almost 200 reports of drink spiking and 56 reports of injection spiking have been made to UK police forces over the last two months.
And one Greater Manchester hospital is understood to have seen ten patients through its doors this last weekend - all presenting with symptoms that suggested they may have been spiked.
Manchester Foundation Trust, which runs the hospital, declined to comment and said it was a matter for police.
Greater Manchester Police also declined to comment and would not confirm if they had received any recent reports of drink spiking.
Mr Lord - who is also night-time economy adviser to Mayor Andy Burnham - said testing at his club is one of a number of measures aimed at cracking down on spiking incidents.
He said educating clubbers and customers about spiking is another ‘interim’ measure while Greater Manchester leaders work to come up with a more fulsome plan.
He said most event organisers take safety extremely seriously but drugs will never be completely eradicated from venues.
As such, education about spiking is vital, he said.
But he added: “It should not take a bottle top to make a woman feel safe.”
“I think men, boys, lads - we need to be looking at ourselves and it needs to be sorted out because it’s a disgrace what’s going on.”
Hundreds of people turned out to a protest in Manchester city centre last week in response to the spate of reports of drinks being spiked and women being injected.
People across the UK boycotted clubs on Wednesday night following the reports.
Both 42nd Street and The Venue nightclubs, in Manchester city centre, closed their doors in solidarity with the boycott.
In Manchester, police are investigating after three girls fell ill at Ark nightclub on Deansgate Locks in September.
While a string of young women came forward to say their drinks had been spiked in Fallowfield and the city centre.
Sacha said the Night Time Industries Association is calling for a public inquiry into spiking - a move he would support.
He is also calling for tougher sentencing for those found guilty of drink spiking.
“We should be able to cut through this red tape and give tougher sentences,” he said.
He added: “I was amazed at how many women turned up to that protest - there were about 800.
“We spoke with the organisers and I have been on a couple of meetings with organisers from different cities working closely on this. We’re meeting organisers of the protest again at Manchester University this week.”
He also praised the bravery of campaigners who admitted they had been spiked.
“They have done a really good job of getting this conversation out there,” he said.
“They have turned a taboo topic into a national conversation.”
In total, police forces across the UK had received 198 reports of drink spiking and 56 reports of injection incidents from September 1 until October 23.
This involved both male and female victims and the alleged offences took place at licensed premises and private parties.
The National Police Chiefs’ Council, which collated the results, did not give a regional breakdown.
Greater Manchester Police did not release the regional figures when asked by the M.E.N.
NPCC lead for drugs, Deputy Chief Constable Jason Harwin, said: “We have now had responses from all forces across the UK in relation to incidents involving some form of injection, with a total of 56 confirmed reports from across September and October.
“Police forces are investigating incidents and continue to work with pubs and clubs to increase searches and guidance to staff.
“We will continue to analyse the reports and work with police forces, plus other law enforcement partners including the National Crime Agency (NCA) and Regional Organised Crime Units (ROCUs), as investigations develop to build a problem profile and determine any further action by police or venues.
“We would encourage anyone who believes they have been a victim or witness to spiking, in any form, to contact their local police force.
“Any reports of spiking will be investigated and taken seriously. You should try and report it to police as quickly as possible to help officers carry out tests and gather the best evidence.”
Hundreds of cases including drink spiking and injections have been reported in recent months.
But the issue is not a new one.
Sunday Brunch host Simon Rimmer last month admitted to feeling “terrified” after his daughter’s drink was spiked several years ago.
The chef, who runs Greens in West Didsbury, said his daughter Flo was targeted around five years ago while out for lunch with friends.
Simon said his daughter, now 24, ended up in A&E following the incident.
Appearing on Steph’s Packed Lunch on Channel 4, he recounted it as a “horrible time”.
“Flo’s 24 now but about five or six years ago she had her drink spiked,” he said.
“She had been out for lunch with some friends and she’d had about three glasses of wine.
“She came home and was in a right state. We were saying to her, ‘How much have you had to drink?’
“And she said, ‘I’ve literally had three glasses of wine, I’m really scared, I don’t know what’s happening’.”
Simon, 58, added: “We took her to A&E and, I’ll be honest with you, they sort of thought, ‘You’re just over-anxious parents, your daughter’s had too much to drink’.
“But it wasn’t, the behaviour was completely different. It really, really shook her up, it was a horrible, horrible time.”
Rimmer said he felt “terrified” during the experience.
He described his daughter as “very open, she’s pretty sensible – she likes a party, like most young people do, but you feel that fear that really hasn’t gone away”.
