Dr Rebecca McKetin, of the Centre for Research on Ageing, Health and Wellbeing in the ANU College of Medicine, Biology and Environment, and colleagues tracked 278 methamphetamine – commonly known as ice – users over several years and found a clear dose-related increase in psychotic symptoms during periods of use, with around half experiencing psychotic symptoms when taking the drug daily.
“People describe being followed, spied on – they will take down the number plate of every car behind them, spend hours searching for bugging devices in their homes, and some won’t leave the house because they think that people are waiting for them outside,” said Dr McKetin.
“These experiences are often coupled with seeing or hearing things that aren’t there. It is disturbing for their friends and family and often very frightening for the person.”
On the other hand one has to wonder if a daily ice habit would not lead to significant well founded fear of both the police and the crime groups selling the drug.
It seems the symptoms clear up when the drug use ends too.
