The Seanad has passed an emergency law to introduce the ban on drugs like ecstasy and crystal meth.
The Misuse of Drugs (Amendment) Bill will now go to President Michael D Higgins this afternoon to be signed into law.
Assuming the President is happy to sign the bill ahead of schedule, the ban on the drugs will be reimposed from midnight tonight.
The ban on over 200 drugs was overturned yesterday when the Court of Appeal struck down part of the law as unconstitutional.
