Foo Fighters drummer Taylor Hawkins had ten different substances in his system when he died – including marijuana, opioids and antidepressants, Colombian officials have confirmed.

Preliminary results of the urine toxicology test found he had ingested THX (Marijuana), tricyclic antidepressants, benzodiazepines, and opioids, the Attorney General’s Office said.

Officials said on Twitter: “The National Institute of Forensic Medicine continues to conduct the necessary medical studies to ascertain the cause of death.

“The Attorney General’s Office will continue to investigate and will duly inform the findings of forensic examinations in due time.”

Hawkins, 50, had been with the rest of the band in the country’s capital, Bogota, when he died in a hotel room.

They had been due to perform at the Estereo Picnic festival near Bogota on the night of his death – but have now cancelled the rest of its South American tour.

The group are due to tour the UK this summer, with shows scheduled in London, Birmingham, and Manchester. It is not yet known whether these will continue.

On Twitter, they said: “The Foo Fighters family is devastated by the tragic and untimely loss of our beloved Taylor Hawkins.

“His musical spirit and infectious laughter will live on with all of us forever.”

Foo Fighters – Nate Mendel, Pat Smear, Chris Shiflett, Rami Jaffee, and Dave Grohl – have won 12 Grammys and were inducted into the Rock & Roll Hall Of Fame last year.

Hawkins was born in Fort Worth, Texas, and is survived by his wife Alison and their three children.
