I'll chime in, since we made eliquid out of fresh buds and plant leftovers.
Basically we followed this guide to some extent:
Stealth Vaping With DIY Cannabis E-Liquid - Vaporblog: All Things Vaporizer! - Vaporblog
We did use around 5 gram of fresh bud (popcorn buds only, since it was a test), and around 25 gram of grinded up leafes, stems and such which had trichomes on it.
We took our material, put it in a waterbed, and poured around 200 ml PG over it, and heated it so it was barely simmering for about 6 hours. After that we sifted it through cheesecloth several times, and lastly through a coffeefilter, since there was allot of plant rests in the liquid. I think we got a total of about 120+ ml liquid. The liquid is then vaped in an atomizer, like Kanger Pro or Evod, just like any other juice. We added a bit of VG for clouds, and liquorice flavor. You can vape this anywhere without it smelling like weed.
Now, the effect of it is there. We used popcorn buds and leftovers, so we didn't use the most potent material, so we have to vape atleast 10 puffs or so to feel it. If we continue vaping the effect is greater. However, next harvest we're gonna use some better bud, and more of it. It really does work. The liquid is golden brown when finished.
