I've posted a new thread on this subject of OA vape with honey supers present.
In conclusion, I think we're being far too cautious about treating hives with OAV with supers present.
Based on my back of the envelope calculations, 1 lb of honey from a full round of OAV treatments (2 brood chambers and 1 honey super) will contain, at the most, 20-40mg of oxalic acid. Based on a quick google search, oxalic acid content of a bowl of grits, a cup of almonds, or a mixed salad is 100+mg of oxalic acid.
Therefore, I cannot conclude that OAV treatment with honey supers are a particularly strong health risk. Especially if it's clear that eating a mixed salad with almonds will result in 10X + the amount of OA from the total amount of OA in 1 pound of honey.
Seems likely to me that even consuming half a gram of oxalic acid mixed in water would probably not cause severe health effects. There's little chance, in my opinion, that OA concentration in 1 pound of honey would ever increase to 100mg - the same amount found in a mixed salad with almonds.
Therefore, I cannot conclude that even the most aggressive treatment of Oxalic acid vaporization would render honey remotely unsafe for human consumption.

You are confusing practicality with reality. OAV had a history of decades long use in Europe, however was a registered pesticide in the US from 1957.

Anybody got a later version?
It is not true that you cannot teach an old dog new tricks.
They can learn them, they just can't do them.
