An inquest is due to place into the death of a middle-aged man after taking the former "legal high" drug mephedrone.

John Sterling Smith, 46, suffered a cardiac arrest at his home in The Drive, Hove, in the early hours of February 7.

Toxicology tests confirmed he had taken the drug, known by various names such as meow meow on the UK club scene.

Sold over the internet as plant food, the substance was made illegal last month after being blamed for a number of deaths and is now classified as a Class B drug.

It has similar effects to amphetamines and can cause temperature changes, heart palpitations and paranoia, according to the Advisory Council on the Misuse of Drugs (ACMD).

Other side-effects are said to include headaches, psychosis, weight loss and insomnia.

Two men from Brighton were arrested on suspicion of supplying Class A drugs in relation to Mr Sterling Smith's death but have since been stood down from bail without charge.

The inquest will be held at Brighton County Court from 3pm.
