Help Propane/butane inhalation questions

[リンさん]

Unfortunately search function seems to be down, but Im still curious if anyone here had experience with inhaling propane or butane.

How does it feel? How much would you realistically need to pass out from it? For how long can it knock you out?

It's possible to pass out in a few seconds by doing deep breaths.
