This is more because folks huff canned air to get high. The first time I heard of this was someone huffing air freshener, but canned air doesn't have as much... smell, yet still has propellant enough to get high.

I worked in a pharmacy for some years. A teenager came into the store one day, went to the stationary isle, and started huffing the canned air. Dude was a bit violent towards the pharmacist, who was checking to see what the noise was. We wound up calling the cops and feeling really badly for his mother, who was waiting in the car in the parking lot.

Luckily, most folks have canned air for normal purposes - and it seems you did as well.

As you probably know, it isn't air but an alkane mix.

I'm more concerned by the label "air" meaning people don't know this. A colleague sprayed it in his mouth... (no harm done, but still)

You can get a buzz off canned air. There's a famous episode of the A&E show 'Intervention' with that topic (walking on sunshine)
