Vegetable glycerin extract is pretty amazing...so far. I made my first batch and everyone loves it. You can put it in dropper bottles for absorption right under the tongue for an immediate high and the more typical smoking effect, or you can put it into gelatin capsules, swallow it, and get a longer lasting and more mellow effect with pain relief and sedation like if you ate a cookie.
Get some food grade vegetable glycerin (I got mine at whole foods, 16oz $10). I used about 80g of trim, as that was all I could fit in my crockpot and cover with the glycerin. You will want to decarboxylate (activate) your trim: look it up for the best results (put your trim on a cookie sheet with the oven at about 240 for about a half hour. seriously though, read up on it, there are other temperature settings and times you can use)
Using a blender to chop up your trim has two benefits: 1) it makes it finer and easier to cover and 2) you'll get to scrape some badass kief out of the base of your blender.
Cover the trim with glycerin in a small crockpot with a 'keep warm' setting. leave it on for 24hours, stirring it frequently.
Strain the trim with cheesecloth.
Funnel it back into the glycerin bottle for storage or fill dropper bottles.
Gelatin capsules can be purchased at vitamin stores, but fill them as needed or on a semi-daily basis because they can deteriorate over about a week.
