I don't have a real vaporizer. I use the cheap, short glass tube (a Ubie from AmercanSmokeless.com), so it may not vape (extract) as much THC as a real vaporizer would. So your results may be different.

With a Ubie, the pot is coarse (not screened or pulverized), but after vaping it, I put the leftovers through a very fine metal screen (or kitchen sieve). This helps get a better alcohol extract since more surface area is exposed.

I soak the powdered, vaped leftovers in Everclear, 95% grain alcohol (illegal in some US states, where they offer a 75% variant) then mix it with pop or juice (you can't drink it straight) and gulp it quickly. You could even use vodka or whatever liquor and drink that. The extract might not be a good with lower alcohol content liquor.

After soaking overnight, I don't filter it through a cloth or coffee filter: I just pour off the liquid, and re-fill the bottle with more alcohol. I can get 3 or 4 batches, but of course with diminishing returns. I'm surprised how much THC is left behind from the initial, and subsequent extractions.

The alcohol extract tastes pretty bad (especially if you've scorched rather than vaped the pot). So mix it with as little pop or juice as possible, hold your breath and gulp it all without taking a breath (since you'll smell/taste it a lot less that way). Picture a mom holding her kid's nose while spooning castor oil down his throat. Afterwards wash it down (chase it) with more pop or juice. If you can accomplish the gulp AND the "chase" without taking a breath in between, the awful taste is MUCH less noticeable.

I get smashed on just two to four table-spoons of the extract. The high will come-on pretty fast, since the alcohol carrying the THC is absorbed through your stomach lining, and goes into your blood quickly.

I'd suggest you start out with a really small dose, since you don't really know how strong the stuff will be. You can get dizzy or even throw-up if you get too high (as with eating too many brownies or too much hash). If you didn't get high with a small dose, the next time double the dose till you can feel it.

If you've made a large enough batch for multiple doses, you will learn how to dose with it, but the next batch you make might be stronger (who knows?).

Be cautious and have a good "trip".
