I've been a net of times myself. I agree there are people that appear to have been taking drugs, but nothing more than any other club I've been in. As has been mentioned in the thread the security is pretty tight in terms of how they search you. However I've only ever been offered drugs once in there on 5/6 visits. The problem with drugs is you can buy them anywhere. Not all these people you saw would have brought drugs inside the club, as was evident from one of the lads that died. Police can't control drugs on the street with the powers they have so there is little chance of a nightclub being able to stop 100% of drugs that came in to a club. Worryingly it's been said the club has stopped and passed police 70 people suspected of drug dealing and there has been 1 conviction. Is closing the venue going to stop any drugs issues? No. People will still take them and go to another club. People need to be educated about what they are doing and understand the risks and signs of themselves getting into differcult if they have taken them.
It's a shame but this is going to end up being another high rise block of apartments, sold to rich, foreign investors as another holiday home, pushing up prices of the local area meaning more hard working local people miss out. It's a shame London has come to this,
Good point regarding the police. They're in no position to lecture others on stopping drug business given their epic fail.
