I vape away happily in front of my little TV most evenings, getting through up to 5ml of liquid during the course of watching Star Trek TNG, NCIS and CSI etc. I noticed that at the end of a night my TV screen is slightly damp with what appears to be condensed juice in a uniform, very thin layer. The PG/VG content makes for a good cleaning fluid when carefully wiped off with a lint free rag. I've been vaping for years and haven't noticed any effect on soft furnishings or curtains but I guess all that PG/VG mist that we exhale must go somewhere. I mean, if you vape 5mls of juice in the same closed room every day and, being very conservative, say only 2ml per day is exhaled, with the rest being removed from the lungs in mucous and ingested, then that means you are putting 730mls of juice into your air each year. Don't get me wrong.. I am a committed vaper and argue strongly if anyone knocks us. But when the heavier than air vapor clouds sink to the carpet then does the PG/VG Stay there? More just interested in what people think than anything. I guess that the exhaled liquid just disperses harmlessly unless you put litres into into the air all at once. Anyone know if there are any studies on this subject?
