"I want to produce the highest quality possible...and it seems like the consensus is to use naphtha to do so. I was planning on 99% ISO...having a hard time finding it. Then I read about everclear, which I can get at any liquor store here...but it seems like people say you get much less THC extracted with this method. Ugh...just writing this post makes me nervous. This stuff is expensive! And I don't want to mess it up. I'll try to post some pics once I get started and let you know my results...but any other tips would be appreciated!

OH! And I have just started to read about this Green Dragon soda/tea stuff....would this be another option?"

If you want the highest quality of an oil that actually does shrink tumors.
Use the recipe from the horses mouth.
"Run from the cure"

99% iso is hard to find.
91% is available at most drugstores
And 70% is useable but also picks up water soluble components that are undesired.
You can remove some, but not all of the water, with table salt.

Same goes for Ethanol.
The highest proof that is commercially available is 181. That's 90.5 % Ethanol.
The highest proof sold in the islands is 151. that's 75.5 %
Same story with water soluble components.

If you can't find clean naphtha, I'd go with the 91% isopropyl.

The trick with alcohol extraction is freezing temperatures.
Put the buds, the solvent, funnel, filter-papers and the containers in the freezer overnight.
Do 2 quick, (3 minutes), washes, keeping everything a cold as you can.
That freezes out the water, chlorophyll, etc. and yields a honey colored, very pure oil.
Then use a fan to do the evaporation at room temperature.

Patience is advised.
When it looks done, do it some more.

It will look like coffee with cream.
Then small black dots form and turn into large, black, globs.
At the end there is some water left over.
It will look reddish.
We call that "red oil."
It has very little psychoactive effect and tastes nasty so we usually discard it.

Then, set it on a coffee warmer and watch it closely.
When large, (air & solvent), bubbles stop and the tiny, (CO2), bubbles start to taper off, it's done.
Start with a match head size dose 2 or 3 times per day and increase the size of the dose as he builds a tolerance.

I advise against using Butane.
It's very dangerous and the end product appears to be less effective as a cancer treatment.
