Inhaled possibly butane?

The lighter looks like this http://www.chemaxx.com/butane_lighter3.htm

I was wondering what would happen if I only pressed the black button but not roll the thing.

I suspected that it might cause the gas to come out, but wasn't sure so I took a sniff. Not sure what the smell was, might of been nothing.

It's been an hour and I seem fine. I heard there could be brain damage or instant death.

Should I still be worrying? Just worrying about it makes me feel like I'm dying..
I'm new here so  I'm sorry if I posted in wrong place.

You're fine.  You didn't inhale enough of it to get high, let alone damage your brain.  But don't do it again.
