Twitter erupted in confusion today, after a stranger-than-fiction legal case saw over 100 drugs including ecstasy, ketamine and magic mushrooms become legal in Ireland for one night only.

Following a decision by the Court of Appeal to challenge the Misuse of Drugs Act 1977 and strike down legislation banning the possession of the substances, the Irish parliament is scrabbling to rush through emergency laws overnight to shut down the loophole.

man prosecuted for possessing methylethcathinone in 2012 launched the case, and denied criminal charges of supplying the substance and argued the regulations were unconstitutional.

The substance also known as 4-mec or snow blow is one of around 100 brought under a blanket ban in Ireland four years ago, which forced head shops around the country out of business overnight.

The court today agreed that the law making possession of methylethcathinone was unconstitutional, and by doing so temporarily legalised the possession of other drugs in the same category due to the way Irish law works.

Twitter users were quick to react to the news, and make plans and predictions for the night ahead.
