Over 100 incidents of spiking were investigated by Gardaí in 2022.
That's a near doubling of cases compared to the previous year.
Gardaí released the figures in response to a parliamentary question, submitted by Sinn Féin TD Mark Ward.
12 cases were investigated in 2020.
However, in 2021 figures increased to 62 investigations, and last year 106 cases.
Chief Executive of the Dublin Rape Crisis Centre, Noeline Blackwell, defines spiking.
"It can be somebody giving somebody a triple shot of something instead of the one that they asked for, pouring a bottle of something into a punch that nobody knows about.
"Adding an extra naggin of something into someone's drink that they're not aware of, as well as putting some drug into the system."
In a written response, the Justice Minister urged anyone who may have been a victim or witness to an assault, to report it to Gardaí.
If an individual is found guilty of such an offence, they can face 3 years in prison.
