The Monkees star Davy Jones died with a marijuana-type drug in his system, according to toxicology reports.
The British-born singer passed away in Florida in February (12), aged 66.
Autopsy results showed he died after suffering a severe heart attack and now toxicology tests have since showed he had cannabinoids in his body too.
The substance did not play a part in Jones' death and tests for all other drugs came back negative.
The new report, released on Thursday (05Apr12), also noted Jones had congestion in his lungs.
