... Its a shame the PEG doesn't seem to get along well with me. It could be an allergy or apparently related to an immune thing I have. I will say this all my friends LOVE the ejvape and the extract with the ejuice. Makes me a bit jealous, but I've hardly got anything to complain about with my extract straight up.
The ejuice is a blend of PG and PEG (the reason for the blend was explained in great detail by Liquidizer much earlier in this thread), but if what you don't get along with is
just the PEG in the ejuice, you might consider pure PG for those times when you want your concentrate to flow well enough to use in a standard e-cig type clearomizer.
So we need an ecig with no carrier just pure oil can u say cera lol. Not for me but seems to be one of the few options at the moment.
There are a number of (what are commonly called) bridgeless dripping atomizers that will work just fine with thick oils and other extractions. They're available for about $5 each. Unlike the Cera EO cores, they work just fine on little eGo style batteries, which last for days before needing recharging, and are available in regulated variable voltage models in the $20 range. If your concentrate has been winterized (had the plant waxes removed), they'll last for months. If your concentrates are pretty waxy, they'll need to be cleaned every few days or so, but still should last a while. They won't hold the amount of concentrate that a Cera EO core will though, so you have to "refill" them every half dozen or so hits.
I've been using a Smartvapes 1.5Ω bridgeless dripping atomizer with two kinds of "waxes", three types of oil, and some really thick sticky stuff that I don't know what it's called; all of them work great. You can even get "nail dab" strength hits if you want (which I don't), by turning up the voltage a little bit and giving the atty a five second warmup before taking your hit. I've also dripped some Pure Gold into it, though because it's fluid enough I usually use the Pure Gold in a GotVapes "Sapphire" buddy clearomizer, which holds about a gram and lasts for weeks and weeks without needing a refill.
There are actually lots of ways to enjoy good concentrate, but because I live in an apartment in NYC, I really can't take advantage of the Liquidizer Herb2Vapor System, and I have to buy "ready made". It makes me nuts because I would really like to be making it myself...
