Also now and then someone decides to drive a car while inhaling NO2, which as you can imagine, is not really a bright idea.
These are rare cases but unfortunately these people are spoiling it for the rest.
These people aren't spoiling it for the rest. The government was always going to ban it because:
(a) the government and the opposition always favour authoritarian drugs laws; and
(b) they are unpopular and (due to ideology) incapable of solving real problems, so they announce terrible policies instead.
There was petrol sniffing, and then people having a cigarette afterwards.
The glue sniffing.
So many silver phials dumped on the pavement, now people are buying the catering sized canisters of Nitrous oxide, and dumping that too.
Ok, can not emphasise with that, at all.

How? Why? It completely takes you out of commission for a few seconds / minute(s?) at best. Why would one take THAT while driving, it makes no sense.
It's not taking it while driving, it's taking it before it was purged from your organism.
