Matthew Perry had prescription drugs including anti-depressants and anti-anxiety pills at his home at the time of his death - but no illegal medications, a police source claims. The law enforcement mole told TMZ that the Friends star - who died Saturday aged 54 - was also in possession of a prescription COPD drug. COPD stands for chronic obstructive pulmonary disease, with the meds found at Perry's home usually used for people with emphysema or chronic bronchitis. Perry was a smoker and had also battled an addiction to alcohol as well as opiates, but claimed to have been clean shortly before his suspected drowning death. The fresh revelations came after it was reported that EMTs were called to the home of the Friends star for a 'water emergency' and arrived to discover the actor had drowned, it is claimed. Police sources told NBC News and CNN that they'd initially believed they were attending a possible 'water rescue' at the funnyman's Pacific Palisades home after being called at 4:07pm PST Saturday.
