Mr Fone said when the girls declined the tequila shot he volunteered to take it, and it was given to him reluctantly.
"After I had it the guy came up to me, the music was blaring and he was saying something to me, I couldn't understand what he was saying and then I finally caught it, 'Rohypnol's in there'.''
Mr Fone said the man quickly left after that, leaving him standing there processing what he had just been told, "I Googled it on my phone and then thought `f***'.
"I ran to the bathroom and tried to throw it up but it wasn't working, I couldn't get anything out.''
He told his friends and the girls at the bar who were shocked, "I just said, 'oh well, better me than you' and then she said, 'yea, that's what I was thinking' ... It basically killed the night.''
"In the space of 10 to 20 minutes I just got really drunk.'' He said he took a taxi home, then started to feel drowsy and passed out within the hour, not waking up until 10 to 12 hours later.
Mr Fone said he elected not to go to the hospital as when he Google searched the drug he deemed that he would be in no real danger as long as he got himself home while he was still awake.
A spokeswoman for the Wellington Police Watchhouse said it was once in a blue moon that drink spiking was reported.
She said the victims were usually female and come in up to two weeks after the incident when it is too late to police to prove anything through medical checks.
A spokesman for Wellington Hospital said there were no statistics kept on how many people are dealt with by the Emergency Department due to drink spiking.
