"Thank you for your interest in Ploom. At this time we do not have any plans for additional mouthpiece designs. To my knowledge, there have been absolutely no concerns with plastics offgassing. For further information on this point, please se our FAQ: http://www.ploom.com/support#what-will-the-vapor-come-into-contact-with-before-reaching-my-lungs If you have any other questions for us, please do not hesitate to ask." Not sure why I remember people reading about new mouthpieces in the works, but the answer I just got via email seems to indicate otherwise? Also the answer on offgassing, while supposed to be comforting, is actually doing the opposite. "to my knowledge" isn't confidence inspiring. "no concerns with plastics offgassing" doesn't mean there is no offgassing, just no one is talking about it? Perhaps I'm reading too much into the wording on this part, and I know that may simply be the case. But it also makes me feel like there was no testing done to ensure no offgassing, or I'm sure that would be used as a selling point. Does anyone know how, as the consumer, I could do a test for something like this? Better than just looking for visible gasses which do not exist. I love my pax and continue to be impressed, but I want that certainty for peace of mind.
