Methanol THC Extraction

Howdy All,

I have been a small-scale grower for 35 years. I prefer smoking bud, but I have recently begun to appreciate vaping, especially after I mixed some menthol flavor in my last batch.

I have decided to try my hand at concentrates, specifically Hash Oil.

I have tried the BHO method and produced some awesome oil, but butane is a tad pricey and seriously freaking dangerous... I knew a guy in Louisiana that was blasting outside and his cat walked up during the run. Yep, you guessed it. He touched the cat, shooing it off the table and set off an explosion.

Not, that I am worried... I just know how things happen.

I have done an Ethanol extraction and it was good, but the chlorophyll changes the taste and I love the amber liquid. Did the sunlight thing to get rid of the chlorophyll and did not care for the result.

Now I am considering a methanol run.

The Plan:
1. Grind bud.
2. Decarboxilate in the oven at 220 F.
3. Place in glass container covered in Methanol. Store in the dark , periodically agitating for 24 hours.
4. Strain through cheesecloth.
5. Boil off most of the Methanol using a stirring hotplate.
6. Add EtOH wash (190 Proof), agitate and boil off once again, this should also remove all of the remaining methanol.

This should produce a beautifully clear amber Hash Oil, without the danger of turning yourself into Richard Pryor.

Has anyone tried this process? Is it better to decarboxylate before the methanol?

Methanol is only a poison when it is present... I have used it quite a bit for other applications. I know the EtOH will blow the Methanol out, I am just wondering if is it a waste of my time. I want clear BHO hash without the butane.

Just use BHO and don't touch no pussy after.... geez.... don't make it any harder then it needs to be.

You can get a case of whipit drop shipped to your door for just over 50 bucks. Can make almost 100 grams from that....

If one is that worried about static electricity then a ground strap on the wrist (like the ones you use to work on laptops) can be used. By the way, doing the extraction in enclosed areas where the BHO accumulates to explosive levels is kind of silly to do; get some ventilation.
Or do it outside.

Guys... he was outside. The butane was in the middle of the run, the cat heard the hissing and was curious. My buddy was shooing the cat off the table and barely touched it. That little static charge was enough to singe the cat and my buddy, it also blew the extraction tube apart.

I have made mercury and silver fulminate, nitroglycerin, and Semtex. At my age you realize how stupid things like that are, and how lucky you were that fate intervened and allowed you though those natural selection events. Now I try to avoid the entire situation as opposed to having to pull a magnificent idea from my fourth point of contact.

Agreed I buy cases of Whip-it for $48 delivered and I average 3gr of wax per can. I run 4 cans through my oversized tube and get 10-12g per tube. Outside, no flames or sparks with a breeze.
I find it very hard to believe that a cat and a person BOTH OUTSIDE ON THE GROUND (earth ground) would carry any static electricity. This would about be impossible. Maybe he was to embarrassed to admit that he wasn't thinking and lit a doobie.

I don't know about that . . . I've had a fire start through a spark from static electricity before, however, it wasn't butane. It was ether and while it did happen outside (it had gathered under a tarp being used for shade which is what caught on fire), it was over 100°, no breeze and the ether had previously been distilled to remove the "upper cylinder lubricant" (motor oil) so it was extremely volatile.
However; I'm pretty sure that cat has satisfied its curiosity and will likely avoid the operation in the future.

From what I read Everclear is the best because it is a food product. No idea about isopropyl alcohol but in theory if you got 99% and it all evaporated that could be inexpensive. Don't know the affects if any is left over but it seems like it might be better than butane. I'm not a doctor though so : )

Everyone around here uses Iso alcohol. It can be tricky too. My bro in law burned both eye brows off couple years ago -- sumbitch looked funny for couple weeks
