An Australian man was briefly paralysed after accepting a drink from a stranger.
The man, in his 20s, was at a hotel by the sea in Adelaide on January 19, local media reports, when he was given a shot.
Shortly afterwards he began feeling unwell, so was rushed to hospital where he spent two days without the use of his legs.
He is reportedly back on his feet, but still feeling unwell.
A toxicology report is still being prepared, but detectives suspect the drink was spiked with GHB or its more powerful variant, GBL.
Police are looking at CCTV footage and urging witnesses to come forward.
According the NZ Drug Foundation, the effects of GHB -kick in after about 15 minutes, and include lowered inhibitions, increased sex drive, dizziness, nausea and memory lapses.
Though originally developed as an anaesthetic, the side-effects have seen it become widely known as a 'date rape' drug, though the Drug Foundation says its actual use as one is quite rare.
"It is expensive, has a strong taste and is much more likely that drinks are spiked with additional alcohol," its website states.
