There's been a rise in the number of Irish people indulging in the unsafe practice of taking 'mystery white powders'.
Up from last year's 9.2%, 11.9% of the 2,392 respondents here say they bought MWPs, which both anecdotal and medical evidence indicates are often ketamine or mephedrone, one of the then legal highs banned in 2010 by Mary Harney.
"All you do when you ban a drug is drive it underground," notes the GDS' Adam Winstock. "Only in Poland (19.1%) and the UK (13.7%) are mystery white powders more popular than they are in Ireland, which worries me. Why would people take something not knowing what it is? Because 80% of them are already pissed or high. It's about old school harm reduction; don't try something for the first time when you're off your face. The group I would really emphasise is young women. Don't go and snort a random white line from a bloke at a party you don't know. You think it's coke, but actually it's a sedative that leaves you mute and unable to move and you're sexually assaulted."
The Global Drug Survey 2015 was conducted in Ireland in partnership with Hot Press, The Journal and Spin. We'll have more coverage of its finding as the day unfolds.
