Six people have been hospitalised after taking suspected legal highs at this year's Parklife music festival, police have said.
One woman remains in hospital for treatment but her condition is not yet known.
Organisers warned festival-goers that amyl nitrate, known as poppers, was being misused as shots on Saturday.
There were 25 arrests at the first day of this year's two-day event but there were no major incidents, said police.
Eleven arrests were for drug offences, two for assault, with the remainder for offences such as theft.
The annual music event has attracted about 70,000 festival-goers to Manchester's Heaton Park.
Parklife tweeted: "Please be aware poppers are being misused as shots. Don't consume anything not sold from our bars, if you do seek medical advise (sic) immediately."
A fresh appeal in relation to Robert Hart's death, who died four days after he was assaulted at last year's event was launched at this year's event.
The 26-year-old from Macclesfield, Cheshire, was punched in the head near the main stage on 7 June.
His attacker has never been found, despite a £23,000 reward offered by Parklife organisers and Crimestoppers.
Greater Manchester Police has issued an appeal called #helpbobby for people to share last year's pictures and videos from the festival online in the hope it generates new leads.
