Inhaling laughing gas

Last Monday it was reported how Alexandre Lacazette is breathing nitrous oxide (which is also known as laughing gas). Doing it in a sitting position, the 29-year-old is inhaling this chemical compound from balloon while his eyes are closed. This incident is the second of its kind from the striker where 18 months ago had done the same, received a punishment from Arsenal, and he can experience that again heavily now after this stupidity.
