I used to be a pretty bad asthmatic through my entire childhood, but grew out of it in my mid-teens. Before then, I needed to use an asthma inhaler almost every day at some point. I was prescribed the Ventolin Albuterol inhaler and took it as needed, before exercise so my asthma didn't flare up, etc. At the time I was too young to even know that it could *conceivably* be used recreationally; although I did notice I felt extra refreshed after each spray. From my recollection of it, this was a very temporary "feeling", and not something I feel anyone could really get hooked on.

I do remember, though, when asthma inhalers were sold OTC for a short time.. the main reason they had to be restricted to prescription only again is because young kids got a "kick" out of them; there was too much inappropriate usage going on.

I don't know about the devices you mentioned; the active ingredient in those is different from what I used when I had asthma. But I imagine the same principle of action could be similar, where there's a short-lived feeling of relaxation after usage (again, I don't know.) If that's the case, it's certainly no where near as addicting as other drugs; but on the same token, definitely *not* something to fool around with.

I'd sort of put it near the category of using household chemicals for a quick buzz--just too dangerous because you can't know the full extent of the effects.

But again, I don't know the details of your situation.
