In various contexts, I have heard such specks identified as residual burnt (carbonized) juice, and the remnants of whatever couldn't vaporize, possibly including flavorings, colorings, oils, sweeteners, etc. And, that it's the same thing that accumulates on atty coils. (It's also more common in the Carlos juice Box mod, with its homemade atty.) Was not typically thought to be harmful in what I've read. I don't recall hearing of it specifically in regard to carto condom techniques, but given the foregoing anyway, it would seem within the range of 'normal.' Maybe here it was related to the particular juice type/composition, maybe to the construction of particular cartos since some variances are being mentioned...
Katya, did you catch the critter when he was still donning the black box? Not entirely sure what the new green thingy he's sporting is lol!
Hi Mia,
I thought about stuff like that but it just seems kind of weird. I never even had that with the reg. KR8's. There really was a fair amount of it the first time and I hadn't used it that much. I don't know. Another mystery I guess. What you mentioned has been noticed by others?
