A subsequent inquest determined that her death was not directly caused by the consumption of ecstasy, but rather the result of the large quantity of water she had consumed. She had apparently been in observation of an advisory warning commonly given to ravers which stated drinking water would help her avoid dehydration as a result of continuous dancing. Leah had been at home with friends and had not been dancing, yet consumed about of water in less than 90 minutes. This resulted in water intoxication and hyponatremia, which in turn led to serious swelling of the brain, irreparably damaging it.
