Arsenal said on Friday that they will "remind players of their responsibilities" after a video emerged that appears to show a number of stars inhaling nitrous oxide.
It is believed that the likes of Aubameyang, Ozil, Alexandre Lacazette, Sead Kolasinac and Matteo Guendouzi began inhaling balloons containing nitrous oxide, also known as laughing gas, which is also commonly referred to as "hippy crack".
CCTV footage obtained by The Sun showed numerous club's senior players inhaling balloons of the gas (also known as "hippy crack") during a party which took place ahead of the start of the season.More news: China launches rover for first far side of the moon landing

"The players will be spoken to about this and reminded of their responsibilities as representatives of the club", read a statement on Arsenal's official website.
Nitrous oxide is legal to possess, but it is illegal to sell it or give away.
