"Two days before her death, Wilkes and Chloe had taken a gram of cocaine and a gram of MDMA between them, staying up all night.
The following day, Wilkes bought another gram of MDMA and each wrapped half a gram of it up in a cigarette paper and swallowed it with water - "a method of ingestion called bombing", the prosecutor said.

"A toxicology report showed Chloe had 3.1mg of MDMA per litre in her blood, enough to prove fatal.
Cocaine was also found in her blood, the court heard.
Wilkes, who split up with Chloe's mother when she was nine or 10, later told police his daughter had been taking drugs, including MDMA and ketamine, since she was 13 years old."
The normal dose of MDMA would be around 0.1g.
