Blame for the death of a Perth teenager "can't just be laid at the feet" of the potent brand of alcohol she drank at the end of her 18th birthday party, an expert witness has told an inquest into her death.
Nicole Bicknell died in November 2014, after celebrating with family and friends at a barbeque at her mother's home.
The inquest has been told that over about 7 hours she is estimated to have consumed about 20 alcoholic drinks, including vodka mixers, liqueur and at the end of the night, and a high-strength liquor called Polmos Spirytus Rektyfikowany.
The drink, more commonly known as Polmos, is a rectified spirit from Poland with an alcohol content of 95 per cent.
When Ms Bicknell was taken to hospital she was found to have a blood alcohol level of 0.319, and a post mortem examination concluded she died from acute alcohol toxicity with early pneumonia and aspiration.
Today toxicologist David Joyce told the inquest the teenager's death was from "the sum of all the alcohol she'd taken that night" and could not "be laid at the feet of just that drink (Polmos)."
Ms Bicknell was described at the inquest as a "naive drinker", and Professor Joyce said her inexperience with alcohol would have made her "fully susceptible to poisoning".
Professor Joyce said his advice to people who are with anyone who becomes unresponsive after drinking was to get them help as quickly as possible.
"Anyone who is unconscious and unresponsive is at risk of losing their life and represents a medical emergency and needs urgent medical attention," he said.
Earlier, Ms Bicknell's boyfriend Jason Mark Roberts told the inquest he woke the next day to find her unresponsive, cold and with blue lips.
He described how he had carried Ms Bicknell to bed in the early hours of the morning after she started to fall asleep, placed her in the recovery position, monitored her breathing and assisted her as she vomited.
At the end of the inquest today, deputy coroner Evelyn Vicker addressed members of Ms Bicknell's family directly, describing the teenager's death as "terrible tragedy."
She said the purpose of the inquest was not to lay blame with anybody, but to find out exactly what happened and educate the community to prevent a similar tragedy happening again.
Ms Vicker told the family whilst her findings would not be handed down until later this year, her verdict would be that Ms Bicknell's death was by way of "misadventure".
