I have used CBD isolate that I have purchased to make oil for myself and my pets. I paid $30 for 3 grams, which is not a bad price. Cuts out some of the steps and you can dose accurately.
I use ethanol for my canna caps, none remains as near as I can tell, and one beer will have me on the floor in pain. Well, a regular beer… oddly light beer is just weak enough I can sneak one every once in a while.
I had made gummies with the tincture as well a while ago, results were great. I also give any edibles I didn’t make a sniff test. If you smell ethanol it’s not dry yet.
