One problem with it is I’ve heard medical calls where someone inhaled the balloon while they were under the wah wahs. Trying to get a deflated balloon out of a person when it’s clinging to the inside of their throat is very difficult in the field.
But just for kicks The other Master speaks. (Warning: NSFW).
I have tried this stuff (legally, at a UK music festival) and was greatly underwhelmed.
The most unpleasant side-effect I’m aware of is the multitude of little metal canisters the Youth of Today drop on the floor after inflating their balloons. I haven’t found any on my lawn as yet, but imagine it’s only a matter of time.
Back when I was in college (during the Cambrian explosion) one wanted to party with the dental fraternity, because you didn’t need the balloons.

Harmful side effects are lack of oxygen and B12 depletion. I have also heard of someone stealing a tank and then dying from trying to inhale directly from the tank.
One time at my (otherwise excellent and reliable) dentist, he must have got the mix wrong. I started getting nauseous during the procedure (a sign of too much gas) and it did…something to my head. Usually for me, once he turns off the gas, it’s like flipping a switch. No residual effects. But this time, I was thinking weird (not “high”, weird) for about half an hour. I don’t ever want to go through that again.
I’m wondering why you doubt this?
The biggest issue I was always warned about was people putting on masks when alone, passing out, and never waking up. Balloons were always said to be safer.
