Photo by Gardaí investigated 106 spiking incidents in 2022 - twice as many as the year before.
62 incidents of drink and needle spiking were probed in 2021, while 12 were investigated in 2020.
The true figure is believed to be even higher, as many people don't report drinks tampering.
Dublin Mid West TD Mark Ward, says an awareness campaign is required for industry employees including barstaff and bouncers:
"What I'd like to see is if people are behaving suspiciously in the a nightclub or a pub, or people feel that someone's acting suspiciously, that they can actually go to the barman or go to the security and say I feel this person is acting suspiciously and that might be able to prevent something happening."
