According to the figures, while the overall number of drug users who prefer ecstasy has fallen down, 27 percent in 2011 compared to 31 percent in 2010, the number of ecstasy users who preferred ice has risen by 9 percent during the same period.
Moreover, almost 50 percent of drug users who use Injectable drugs revealed that they preferred ice to other drugs. The report also added that the number of drug users who admitted to experiencing drug induced psychosis more than doubled, up from 3 percent in 2010 to 7 percent this year.
"What we've found is that there has been an increased rate of self-reported psychosis. It's self-reported, so it's not a clinical diagnosis, and it isn't a very high prevalence. At the same time, any increase in that effect is very worrisome", the agency's senior lecturer, Lucy Burns said.
