The doors of one of the country's biggest nightclubs reopened on Friday, ending months of enforced closure.
Fabric, in central London, had its licence revoked in September, after Islington Council found it had a "culture of drug use".
Last year Jack Crossley and Ryan Browne, both 18, died in separate incidents after taking illegal substances in the venue.
Eager revellers keen to hit the dancefloor could be seen queuing as bouncers asked for identity documents to be out and ready and club staff reminded partygoers about their welfare areas.
The club, in Farringdon, re-opened its doors after all parties agreed to new licensing conditions including a raised-entry age and tougher security measures.
Ricky Payne from Hayes, west London, said its reopening is "brilliant" and "absolutely amazing".
The 27-year-old added: "Where else do we have to go? It is the best club in the world - an institution."
On the issue of drugs, he said it has "always been strict" but he said "people got them in".
Fabric's licence conditions include a ban on anyone under the age of 19 entering the venue between 8pm on Fridays and 8am on Mondays.
It also states anyone found in possession of drugs in the club or who tries to buy drugs will be handed a life ban.
The club also pledged to introduce a new ID scanning system, which could be seen being used on entry, and to improve search procedures and introduce covert surveillance in the venue.
A sign at the entrance to the queuing area outside the club greeted revellers with a polite request to "respect our zero policy to drugs".
It added: "Anyone found with illegal drugs will be banned from the venue and reported to the police."
Police, who normally patrol nightlife in the area, were present at the venue to help bouncers at the door.
However Scotland Yard said no incidents had been reported and that there had been no arrests at the club on Friday.
