    Fast and easy Vegetable Glycerin Extraction method.

    I was reading various extraction methodologies the other day and kept going deeper and deeper within the science. The spectrum of possibilities is endless. I chose 3 methods to investigate, Liquid Nitrogen extraction, Alcohol extraction, and Vegetable glycerin.

    The liquid nitrogen process can grow very expensive and is not the greatest extraction method, the alcohol although a great method has a few pitfalls namely its flammable and it needs to go into the oven for every recipe that takes a reasonable amount of time, and lastly the Vegetable Glycerin... Very interesting, some people say to heat it, others do not but the consensus is that it takes about 6 weeks in a sealed jar that is shaken ever day and kept a few degrees above room temperature. I decided I would try an experiment.


    Double boiler method for Vegetable Glycerin Extract (Papa Kief - Collective Consultant and Cannabis Activist. (619) 365-5240 for pictures)

    This is a recipe used to create a vegetable glycerin based tincture to be used in drop form. It is fully activated and need only to be consumed by placing a few drops under the tongue to be immediately felt or ingested what is swallowed will subsequently be absorbed by the body in the GI tract.

    Ingredients (Variable in increments of 8.5ml glycerin per gram)
    1/8 oz well ground high quality cannabis
    1/8 cup food grade Vegetable Glycerin (commonly found at drugstores and pharmacies)


    Tools

    Cheesecloth
    A glass jar and lid
    A glass dropper bottle (for dosing)
    Large pot
    Oven Mitts


    Method

    Grind the cannabis as finely as possible and place it in the glass jar, pour over the Glycerin and stir it all in

    Seal the jar. Heat the pot of water to a simmer and place the jar into the center. The level of the water should be about the same level as the contents of the jar. This will make sure the jar does not float and fall. Let the mixture cook for 6 hours or you can do it longer shaking the contents of the jar often and adding water to the pot as needed to maintain a level of boiling water. Once this is done you will want to pour your mixture through cheesecloth into a bowl. After you have poured it through squeeze the excess from the cheesecloth careful not to break it. I will suggest using gloves for this, however I didnt and I will assure you, this stuff can go through your skin and make you Super Stoned. Just a heads up.

    Ok so here is what I got out of my experiment, a dark green vicious fluid that 1/2 teaspoon is equivalent to 3 marinol pills.

    My buddy who has a perscription for and takes marinol on a daily basis came by and bottomed up a 1/2 teaspoon. Below is how he described the effects of the glycerin as it compares to Marinol.

    * 5 minutes in he said he felt it in his face, pulling a smile and relaxed eyebrows
    * 15 minutes in he said that it is the equivalent to 3 marinol pills, he usually only takes two
    * 30 minutes in he said that he could feel it and it was much more rounded or complete than he experienced with Marinol, he said it felt like an edible but in a very manageable dose
    * 1 hour later he wanted to know how I made the stuff
    * 3 hours later he said he still felt good but the effects were beginning to become less noticable
    * 5 hours later he said the effects were gone and he felt great, not too tired and not weird.


    SO I think that High speed extraction of THC can be done using Vegetable glycerin in a double boil and perhaps a Crock Pot. below is a picture of the cannabis after the experiment

    It appeared to me that there was still THC on the plant material, so I cooked it in butter for a few hours and made some mac and cheese. It definitely still held some THC because I got extremely high but I believe that a longer period in the glycerin or a fruit press for extraction would be needed to be sure.

    elsewhere, ytrewq noted that 'optimal' conversion of thc-a to thc occurs at 248 degrees F, takes one hour.

    as it happens a pressure cooker at 15psi has an internal temp of 250F.

    searching for 'pressure cooker' led me to goober328, who did a test at 10 minutes, said it worked.

    i mixed 1/8 oz of regs (deseeded, processed in coffee grinder until flour-like) with 2 T of glycerin in a mason jar, cooked it for an hour. added 2T of boiled water, after filtering, the resulting liquid is golden, tasty, and effective.

    it's a pretty clean high, i highly recommend this process.

    i wrote up a recipe, it is here:

    DB;

    I wonder how well this would work if you used BHO instead? My wife has chronic back trouble and cannot smoke (it makes her cough too much). I'm looking for a method to add the thc to her wine or mile for ingestion...

    Green Dragon is awesome! Mine is made with Bacardi151, but it works well. 2 droppers full and my body feels fine. I'm not stoned, but I don't hurt.(Fibro and arthritis) 3 droppers and I sleep through the night.

    @halftoke: The more potent your material is, the more potent your tincture is. I would think hash would work well.

    Could you use mix some of this tincture with either shea butter or almond oil for use on your skin for pain?
