I cook dinner up 15 grams of trim in coconut oil, and my flower exams between 12 p.c to 15 p.c THC. If I make brownies in a 13 x 9-inch pan and reduce them into 10 servings as an alternative of 18 (just like the brownie combine says), do I’ve 15 milligrams THC in every slice or 150 milligrams? Please assist, thanks upfront!

Hey, Kitchen Chemist!
What’s cooking? I’m glad you’re double-checking the THC per serving in your pot brownies. There’s a giant distinction between 15 milligrams THC and 150 milligrams THC per serving … and by my math your numbers are off track. I compute your THC per serving to be 180 milligrams or 225 milligrams per serving, relying on the THC efficiency of your flower. Both manner, that’s a super-potent finish consequence.
It’s vital to get the marijuana math half straight in any mouthwatering selfmade brownie recipe, so let’s stroll by means of the numbers collectively. To corroborate the calculations, I requested Jessica Catalano, Colorado-based hashish chef and writer of “The Ganja Kitchen Revolution,” to affix us. It’s additionally value noting that there are different components in play with the efficiency of selfmade hashish oil and these are solely approximations. For instance: Was the trim decarboxylated to activate the THC earlier than it was used to make the coconut oil? (Hold studying for more information.) Additionally, we’ll presume that all the quantity of coconut oil you infused went into this one explicit brownie batch.
To begin with, it’s nice you might have analytical studies for THC efficiency of the trim. It’s greatest to have as correct THC efficiency numbers as can be found to calculate the THC content material of something you cook dinner up with hashish. When the pressure of flower or trim however don’t have analytical check studies for the plant materials getting used, you possibly can collect efficiency numbers from pressure databases and web sites. In any other case, begin with a (very) normal estimate of 10 p.c THC content material for the plant materials you’re utilizing within the recipe.
Listed here are the fundamental calculations:
Step 1: Decide the dry-weight quantity of THC for the hashish used within the recipe.
Step 2 system: Dry-weight quantity of THC (in milligrams) divided by recipe yield = THC milligrams per serving
Let’s begin our calculations with a simple conversion to recollect: 1 gram of hashish has 1,000 milligrams dry weight.
Now, calculate the THC efficiency by taking the whole dry weight of marijuana getting used within the recipe and multiplying it by the efficiency share.
For instance, if 1 gram (1,000 milligrams) of hashish has 10 p.c (.10) THC, then:
So, 10 p.c of 1,000 milligrams could be 100 milligrams THC. Acquired that?
Let’s return to your brownie batch by changing the whole grams of hashish within the recipe to milligrams of dry weight. In your case, 15 grams converts to 15,000 milligrams.
Subsequent, multiply the whole dry weight (in milligrams) of hashish by the THC efficiency share to get the THC content material in the entire batch of brownies. Based mostly in your observe about efficiency variance of 12-15 p.c, we’ll take a look at each the decrease and higher figures:
If the trim has 12 p.c THC efficiency, the 15,000 milligrams of hashish within the brownie recipe incorporates 1,800 milligrams THC.
To tally the dosage per particular person serving, divide the quantity of dry-weight THC (in milligrams) by the whole servings for the pan of brownies. If you happen to reduce your brownies into 10 beneficiant servings, 1,800 milligrams divided by 10 means every portion has 180 milligrams THC.
If the brownies are reduce into the unique steered dimension of 18 parts, 1,800 milligrams THC divided by 18 parts, then every brownie has 100 milligrams THC.
Now, let’s calculate the 15 p.c THC efficiency to your brownie recipe.
The dry weight remains to be 15,000 milligrams of hashish within the recipe. If you happen to multiply 15,000 milligrams by 15 p.c THC efficiency, that’s 2,250 milligrams THC within the brownie batch.
When chopping the only servings, divide the whole THC content material, 2,250 milligrams, by the variety of servings. Sliced into 10 massive items, every brownie would have 225 milligrams THC per serving. If the pan of brownies is split into 18 sections, every brownie would have 125 milligrams THC per serving.
That solutions your fast dosing query IF you prepped the hashish accurately. As Catalano factors out through e mail, “It’s completely vital to notice that if the hashish bud was not absolutely activated on the proper temperature and time, then milligrams of THC are going to fluctuate dramatically.”
Activating hashish flower or trim with warmth transforms the non-intoxicating THCA cannabinoids into psychoactive THC, a course of referred to as decarboxylation — it’s what occurs while you mild a joint or vaporize flower. The fundamental thought on preparation for cooking is to use low warmth for a short while to transform the THCA into THC. Catalano recommends heating hashish to 225 levels for 25 minutes.
Catalano provides: “If the coconut oil was overcooked, then milligrams of THC are going to fluctuate dramatically.” One of the best ways to forestall overcooking is to observe the temperature of the coconut oil if you end up infusing it with hashish and never exceed the smoke level of coconut oil, which is 350 levels. For more information, try this earlier Ask The Cannabist column, “Cannabutter recipe debate — to make use of water, or not?”
As you possibly can see, there are loads of variables that think about, so THC calculations for selfmade edibles primarily are a tough estimate.
Earlier than you get again to baking, one closing observe about dosing. It could be your intention to make high-potency brownies for medical functions — or it’s your private choice. Nevertheless, in case you’re sharing your brownies with different adults in a leisure setting, I like to recommend utilizing much less hashish within the recipe to decrease the THC dosage per brownie in order that no person will probably be shocked by your potent pot brownies. Or reduce them into smaller servings: In Colorado, the usual serving dimension for a commercially made edible is 10 milligrams THC. XO
