Cannabis toxicity caused the death of a Summerhill man, the Pembrokeshire Coroner heard last week.
Lee John Maisey, aged 36, of Windcrest, Church View, was a self-confessed alcoholic, who also smoked cannabis.
On August 23, Mr. Maisey complained of a headache; he had not been drinking for two days. The next morning, lodger Jeffrey Sanders found Mr. Maisey on the lounge floor and could not wake him up.
Mr. Sanders said that Mr. Maisey had taken cannabis for 11 years and smoked around six cannabis cigarettes a day.
Post-mortem tests revealed a high level of cannabinoids in Mr. Maisey's blood. No diseases which could have caused his death were discovered.
A verdict of death by mis-adventure was recorded.
