AMBULANCE calls relating to the drug ice have more than doubled in the past few years, a state parliamentary inquiry has heard.
Ambulance Victoria regional services manager Tony Walker said ice was associated with levels of aggression not seen with most other drugs.
Giving evidence at the inquiry into the supply and use of ice on Monday, Associate Professor Walker said ambulance calls related to ice use had risen 110 per cent - from 282 to 592 - between 2010-11 and 2011-12.
The greatest rise in calls related to young people aged 15 to 29 years.
Intensive care paramedic Alan Eade said ice users could be paranoid and aggressive, leading them to lash out at paramedics.
Turning Point clinical services director Matthew Frei said ice users seen at a clinic run by his service were usually men aged in their 20s to late 40s.
He said they were often new to drug treatment and included working people such as tradesmen and hospitality workers.
