Drug testing tents will be open at Electric Picnic again this year.
The HSE and Garda-run facilities have been used in previous years to identify dangerous drug batches at the festival and notify those in attendance.

Superintendent Eamonn Curley says this doesn't mean it's okay to use or carry drugs on you at the festival:
