( CNN ) Well , it was weird while it lasted . On Wednesday , lawmakers in Ireland rushed to close a loophole that temporarily made it legal to possess Ecstasy , crystal methamphetamine , ketamine , magic mushrooms and a host of other recreational drugs . The loophole was inadvertently opened the day before , when an appeals court invalidated one section of the Misuse of Drugs Act 1977 . The court ruled that Irish governments had been unconstitutionally adding substances to Section 2 of the law for decades . `` We prepared for this possibility . Legislation was prepared and approved in advance by Cabinet , '' Minister for Health Leo Varadkar said in a written statement . `` The emergency legislation ... will re-instate the status quo ante and re-control all drugs that were controlled prior to this judgment . '' The emergency law moved through the Irish legislature and was signed by the President on Wednesday , meaning that the drugs would become illegal to possess again at midnight , a Department of Health spokeswoman told CNN . Varadkar said the temporarily legalized substances -- which include a wide array of synthetic or `` head shop '' drugs -- `` all have very significant health risks that outweigh any perceived recreational benefits , '' according to the Irish Times . The original schedule of substances listed in the 1977 law -- including cannabis , cocaine and heroin -- were untouched by the appeals court ruling and remained illegal . Varadkar also told the Irish Times that the court ruling could affect `` dozens '' of cases , although The Journal of Ireland said the court 's decision will affect only cases now in the judicial process .
The president signs emergency legislation . Obama says he will veto the bill if it reaches his desk.
