According to the Daily Mail, sewage water in London contained:
- 711mg of benzoylecgonine, the main chemical in cocaine, per 1,000 people
- That compares to 393 in Amsterdam
- 243 in Paris
- 233 in Milan
Levels in the capital are nearly double those recorded in a similar study two years ago, results show.
A new report suggests that London could have the highest levels of cocaine use of any city in Europe. Researchers examined levels of illegal substances found in sewage to look at drug habits across Europe.

Speaking at the family home in Croydon, Daniel's father Tim described him as "a lovely mercurial kid".

He was up for adventure. He was a really normal kid. He spent a bunch of his spare time with his girlfriend and played a lot on his Xbox.
This was the first time he'd taken anything and if it could happen to him it could happen to anyone. We very much want to get that message across.
Mr Spargo-Mabbs added that Daniel's girlfriend, who had gone to the same school as him, was "traumatised" by his death.
Police believe Daniel Spargo-Mabbs may have taken ecstasy before he fell unconscious and died. Drugs charity, DrugScope, says some young people are still taking too many risks, without understanding the consequences.

It certainly underlines the risks that young people are continuing to take after all these years with ecstasy and club drugs, maybe from people they don't know.
Buying drugs and not having a clue what's in them. It also underlines the randomness of this. Many people will experiment with ecstasy.
There would be no way of predicting who would end up in hospital.
