Misuse of Drugs Act 1977

The Misuse of Drugs Act 1977, the Misuse of Drugs Act 1984, Misuse of Drugs Act 2015 and the Criminal Justice (Psychoactive Substances) Act 2010 are the acts of the Oireachtas regulating drugs in Ireland. The acts define the penalties for unlawful production, possession and supply of drugs.
In 2015 the 1977 act was declared unconstitutional, immediately legalizing many drugs in Ireland including ecstasy, ketamine, and crystal meth. The situation lasted 24 hours before emergency legislation closing the loophole could take effect.
