The government is set to introduce a new law to make spiking a specific criminal offence in this week's King's Speech.
It is expected to be included in more than 35 bills in the programme announced on Wednesday.
Spiking is already a crime, covered by other pieces of legislation including the 1861 Offences against the Person Act.
But Labour's manifesto, alongside the Conservatives', said creating a new, specific offence would help police better respond to incidents.
