I would even go further: inhaling pretty much anything other than air is harmful in the long-term.

I imagine if you inhaled helium several times a day for decades that it would also mess something up.

I don’t think this really holds up, for example helium itself is chemically inert and not toxic. The main risk from inhaling helium is probably oxygen displacement at a push.

Millions of people have been using inhalers to control asthma too, this well studied and agreed to be safe. This is just off the top of my head.

Turned this thread absolutely useless, thanks.
