Cool thanks guys, I was thinking food grade too...
Question how many grams should I use per 16 oz's of coconut oil?
Hot cannabis essential oils and coconut oil will mix at any ratios, but for cooking, you typically determine how many servings your recipe makes, and mix in that many doses of cannabis essential oil with the cooking oil called for by the recipe.
The cannabis oil that you are using also makes a difference, as all are not created equal, but as a benchmark many can appreciate, a 9-serving Duncan Hines cake mix with the concentrate from the time worn recipe for 1 ounce of prime bud (20/25% yield) would be in the range of 620 to 786 mg per serving. Trim would be about half that.
10mg THC is considered one dose by the state of WA, and only 10 doses may be packaged together, thus limiting you to 100mg THC per package. Our experiments with concentrate Absolutes in the 90% THC range, is that 100 mg is the average tolerance dose.
The reason for the difference is most likely the range of tolerance for THC in the populous, and the number of emergency room visits with ultra low tolerance folks having panic attacks.
If a persons tolerance is unknown, we typically give them 25 mg of a cannabis essential oil Absolute the first time and see what happens, titrating up from there no sooner than every 4 hours, until they reach a full dose.
