HAHAHHA! i trim my nose hairs on a regular basis thank you very much. lol the first time i noticed it was when i was at work and someone told a joke and i laughed quietly to myself. u know... the giggle but the air coming out the nose laugh? well a little sprinkle hit my arm and i was like what the heck!? then i started to just pay attention to it and yes it really only happens after vaping... and of course exhaling through the nose
