Discarded 3.3l/2kg #NitrousOxide canister, on my own street in #Courbevoie. Still no one at town hall or in any police force will acknowledge my reports: we encounter almost dally evidence that consumption of neurologically damaging #LaughingGas is increasing.
By the way, my collection of #NitrousOxide canister sightings, photographed as I go about my business west of Paris, is available publicly - add it to your #LaughingGas awareness kit, to lobby local government for more effort against the neurological public health scourge of young people.
Nitrous oxide, laughing gas
