Fabric nightclub reopens tonight with a 'zero tolerance policy to drugs'.
Islington Council revoked the Farringdon venue's licence last year after finding it had a culture of drug use which staff were "incapable of controlling".
This week an inquest heard how an 18-year-old student smuggled drugs into the venue in his boxers before buying more inside.
Jack Crossley, from Worcester Park, Surrey, died last August after becoming unwell at the club.
Ahead of tonight's reopening the club said a series of new measures had been introduced.
We will have a new security team, new post of Welfare Officer, ID scanning system, improved lighting and the entirety of our staff have received training from Fiona Mesham’s pioneering drug charity The Loop. This is all in addition to our existing welfare measures, which include of a state of the art medic room attended to by two fully trained medics at all times we are open, free dedicated water bar and zero tolerance harassment policy, among others.
