Have you noticed you can't do this anymore?

I'm sure glad some people are backing me up or nobody would believe it.

My brother used to bug me with this before I smoked.

I could do that until 8 weeks ago. LOL! I called it old smoke though. Scary when I think abut it now.

I knew people who could do this back in high school. I could never do it, but it's a silly gimmick.

A gimmick??? It's a super power. Maybe a fairly useless super power, but we all can't have buns of steel you know.

Well I tried to do it, and all that happened my ears popped and a contact lens almost popped out.

I could do that. On family reunions I would entertain the young ones by sticking a cig in my ear and pretending to inhale, while compressing my lungs instead, and blow out a bit of smoke. I can still hear them, "how did you do that?!?!"

I have seen it done although not wanting that as a primary super power decided to forego it and wait on another to develop.

I believe why you could with smoking and not with vaping is not that vaping has caused a structure change, but that what is vaped is essentially water vapor, something the lungs can absorb (like breathing in on a humid day) but when smoking if you don't exhale all the particulate matter that makes 'smoke' some can drift around and be exhaled a second time. The other way is that people will swallow smoke and then burp it back up - as vapor just falls out as liquid swallowing vapor just does not work the same way.
