Good news, substance-dependent lads and lasses: For a limited time only, possession of your favorite embarrassing club drugs—including meth, ecstasy and ketamine—is legal in Ireland.

This morning, an Irish court ruled that the country's Misuse of Drugs Act 1977 had been expanded unconstitutionally, a judgement that effectively legalized all but the oldest and lamest grandad drugs like cocaine, marijuana and heroin.

Ireland's Department of Health confirmed that interpretation on Tuesday, saying the previously banned substances "cease to be controlled with immediate effect, and their possession ceases to be an offence."

Irish parliament held an emergency session to outlaw the drugs the right way this time, but even so, the legislation won't go in to effect until Thursday.

So have at it, Ireland, just promise to only use the following substances (taken from the emergency bill's text) responsibly:
