Call it or meth or ice, it is a rather misleading nickname for the dangerous narcotic methamphetamine.
Now an Australian study reveals that emergency hospital staff need skilled security guards and personal alarms to protect themselves from the often violent and aggressive ice addicts.
A survey at a Sydney hospital has confirmed the ice addicts are significantly more agitated, self-destructive and bizarrely-behaved than other intoxicated people.
Just one in five ice users cooperated with staff, with the remainder displaying signs of anxiety, restlessness and agitation.
One fifth were aggressive, violent and self destructive, according to the study published in the Medical Journal of Australia. The drug has been linked to violent crime, paranoid delusions and drug psychosis.
Doctors at the St Vincent's Hospital said the results had serious implications for police, ambulance and particularly emergency department staff, who needed special training to cope with the behaviour.
"Personal safety must also be taken into account in the design of emergency departments and the provision of equipment such as personal alarms," wrote emergency department director Dr Gordian (Gordian) Fulde and his colleagues.
"Skilled security staff must be readily available to help if necessary and, ideally, prevent problems."
The study analysed all presentations to the emergency department in the last three months of 2006, finding one per cent of the 10,000 cases were methamphetamine-related.
A quarter of these users arrived with police, compared with nine per cent of other intoxicated people, and 40 per cent required scheduling under the Mental Health Act.
