A coroner has warned of the dangers of a legal stimulant as it emerged that a runner who collapsed and died during the London mara-thon had taken the drug in a bid to boost her performance.
Claire Squires (30), above, suffered a cardiac arrest a few hundred metres from the finish line.
An inquest heard that she had bought a powder supplement called Jack3d which contained DMAA (dimethylamine), a drug with similar properties to amphetamines and is said to boost energy, concentration and metabolism.
Her boyfriend, Simon van Herrewege, told Southwark Coroner's Court that she bought it online as she was keen to beat her personal best race time.
