DAVIDE Sanclimenti was seen dishing out “illegal hippy crack” to revellers at an after-party in Manchester this weekend.
The Love Island winner, 29, uses an air canister to prepare balloons for pals in our exclusive video.
The gas was claimed to be nitrous oxide by a whistleblower at the small gathering.
The Class C drug, also known as laughing gas, was re-classified in November and serious users now face two years in prison and dealers, up to 14 years.

Davide has been enjoying a party lifestyle in Dubai and the UK since his split from Ekin-Su Cülcüloğlu earlier this year.
He was out with mates this Easter weekend and was filmed appearing to fill the balloons in the early hours of Saturday morning following the Solaris of the Sun event at Firefly club.
Davide can be seen using a blue pump to inflate the balloons but there is no suggestion he sucked on the gas himself.
A spokesman for Davide declined to comment.
It comes after he was seen sniffing a white powder on an Ibiza bender last summer - the first time the TV dating show couple split.
At the time, a representative for Davide insisted he was snorting snuff.
Ekin and Davide later reunited but broke up for good in January.
In March the Turkish beauty, 29, then went into the Celebrity Big Brother house - with Davide reacting in a late-night video shared with The Sun.
Cheersing a shot, he ranted: “F**k Ekin-Su.”
A source close to Davide said in response: “Davide has understandably been going through a tough period recently and not been feeling his normal self.

“He’s been trying his best to put a brave face on and get back to the fun Davide that everyone knows and loves by going out socialising more and focusing on his fitness to help his mental health.”
