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 one of 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.
Spiking is the action of putting a drug into someone's drink, or into their body through another method, without their consent.
The latest Met Police figures show there has been a significant increase in recorded spiking cases in London in the last few years, with a 13% increase in cases in London last year – after a quadrupling in recent years.
The force received 1,383 allegations of spiking in 2023 and the majority of cases happen in public places, particularly bars and nightclubs.
But the National Police Chief’s Council has said that spiking is underreported and that cases can be hard to investigate because drugs pass through the system quickly.
The King’s Speech is the official opening of the new Parliament, when the monarch reads out the government’s plans for the parliamentary term.
Prime Minister Sir Keir Starmer has said the programme, which is expected to focus on economic growth, will show urgency and that “there is no time to waste”.
Sir Keir has said the government “is serious about delivering the stability that is going to turbo charge growth”.
But as well as economic measures, it is a chance for the new government to set out its key priorities in other areas.
The programme is also expected to bring back legislation to introduce Martyn's Law, named after Manchester Bombing victim Martyn Hett.
The proposed law, which had been promised by Rishi Sunak, would require venues and local authorities to have preventative plans to deal with terror attacks.
Plans were introduced in the last Parliament but did not pass before it was wound up before the election, which prompted Martyn's mother, Figen Murray, to say she felt "let down" by Mr Sunak.
