Is this still safe to use for mixes and vape?
What implications will this have on my mixes?
Basically what I'm asking is if this will now not be as fresh and therefore my mixes won't be as fresh? It was left open in my bedroom which is temperature controlled with central air, so it's not like it's been in any intense heat or anything. Relatively clean space as well. Just made a blue raspberry mix and it seems fine so far...
Thanks!
both PG and VG are hygroscopic. this means they tend to absorb the water from the atmosphere. This is why you cant have 100% pure, and why USP states that once it is open, its no longer USP grade.
Is it going to hurt you? probably not. But, I have to ask, how much is a liter of VG? is it really worth the risk? I mean, of course by all means, do as you like, and you have already made the decision as you have vaped some and it seemed alright (how would you know if it wasn't?)
Meh - I am old, so I care about my body more now.
What? How will vaping water affect you?
I never said it would affect you. In fact, i said "is it going to hurt you? probably not"
however, having said that... there is a reason that people use DISTILLED water in their mixes vs. tap water.. or the moisture collected in their VG from their house.
Your comment "is it really worth the risk" conveys that it will affect you. If OP left it open for a prolonged period of time, that is a risk that it has absorbed moisture. The comment was very doom and gloom and didn't provide any facts apart from that you're old, and both PG and VG are hygroscopic.
pneumonia is literally just water in the lungs, that's why we use VG/PG.
though in the case of OP leaving his cap off, he's probably going to inhale more water vape just from breathing normal air than what his VG absorbed.
Everything you just said is wrong.
No, pneumonia is not “literally just water in the lungs.” It is a bacterial or viral infection that causes inflammation. The fluid on the lungs in pnemonia comes from your own body, as an immune response to the infection or as a reaction to a chemical irritant. It does not come from water vapor in the air. You simply cannot drown from water vapor. Even direct inhalation of water results in involuntary aspiration - coughing to expel water. Please stop the alarmism.
We do not vape with water because water evaporates at a much higher temperature than PG/VG. If you somehow managed to heat up water enough to vape it, you would be sucking in heated steam and scald your lungs. THAT is why we use PG/VG.
EDIT: Regarding the temperature of vapor — I am wrong regarding the evaporation temperature of water vs. PG/VG as the replies below note. Any device is more than hot enough to boil water. (Since I do temp control this should have been obvious. Duh.) But: You really don’t want to vape 100º C water, which would indeed be steam rather than a vapor aerosol. Steam conducts heat much more rapidly than an aerosol, and scalding is still a big problem. For all practical purposes, the most likely effect would be an instant spitting and bubbling of the water as it boils, which in any case would not be pleasant. This of course assumes your are trying to vape pure water. Mixing water with PG or VG would result in a much higher boiling point.
