dark e-liquid

[glycerol]

everyone who uses a clearo knows that topping juice can't go on forever since the juice becomes darker and darker and darker.. at one point (after the 5-th or sixth topping) one has to think what to do with the rests of dark e-liquid when refilling the tank with fresh juice. i personally just spill it in the sink when cleaning my tank. do you just waste the dark stuff? who knows how many carcinogens it contains.. so what are you doing when the mess gets really darkish?

wait, why are we assuming dark juice has carcinogens?

 

[glycerol]

well, because it's the remains of many, many series of boiling processes that actually DO emit some carcinogens thanks to our friend the VG

 

[RobinBanks]

Are we actually sure the dark color comes from boiling?
Also, boiling food opposed to other methods, is considered the safer way to prepare them by reducing a cancer risk...does boiling really create carcinogens?

I'm definitely not a scientist, this just seemed alarming to me.

I only top my tank off when I don't have time or I'm not abke to quickly vape it down to empty as I have flooding issues towards the end.... I'll go two-three top offs before it runs out....

If it's really bad enough, I just pour the dark dregs down the sink.

However, I do not "boil" my juices in my PV set-ups.
