I'm not sure if this has happened to any of you, but I was vaping in a restaurant after dinner tonight. We had gone out for a friend's birthday, and since it was buffet style I didn't start vaping until I had finished my meal. As usual, being my obnoxious self, I wasn't inhaling, but I was creating large clouds of vapor (like most cigar smokers do). Well, immediately after I exhaled a large cloud of vapor, I absentmindedly took a huge breathe and much of the exhaled vapor went back into my mouth, down my throat, and into my lungs. Is that pretty normal? I'm using a menthol flavor so perhaps the effects of inhaling exhaled vapor seemed more pronounced than typical. Personally, I thought that the vapor dissipated so quickly that as soon as it is exhaled, all that is left is water vapor.
