The Dáil is to sit late this evening to pass emergency laws, after the Court of Appeal said the previous law banning drugs including ecstasy and so-called 'legal highs' was unconstitutional.
It means all government orders banning substances like ecstasy, benzodiasopenes, and so-called 'head shop' drugs are now void - and it's no longer an offence to possess them.
The Dáil will sit until half-eleven tonight to pass the new laws, with the Seanad due to give them the green light tomorrow.
However in the meantime the possession of the drugs is no longer a criminal offence.
In total over 100 drugs are affected by the ruling.
