Doing The Math – Cannabis Edible Strength


Hey there, kitchen warriors and cannabis connoisseurs! Ready to whip up some cannabis-infused goodies but want to keep things on the chill side? Calculating how much green goes into your treats is super important to make sure everyone’s having a good time, without any unexpected trips to the moon. Let me break it down for you with a no-sweat guide to figuring out just how potent your homemade edibles are:

Getting to Know Your Bud

First up, you gotta know the strength of your cannabis. If it’s rocking a 20% THC level, that means each gram packs 200 mg of THC. Yep, it’s math time, but stick with me!

Wake and Bake (Decarboxylation, That Is)

Before anything, your cannabis needs a little heat treatment called decarboxylation to get that THC ready for action. But heads up, you lose a bit in the process. We’ll play it safe and say about 80% of that THC makes it through.

The Magic Number

So, if you started with 200 mg of THC, after a little oven time, you’re looking at 160 mg ready to party. But wait, there’s more! When you mix that into your butter or oil, not all of it transfers. Let’s say about 60% keeps the THC train rolling, leaving you with 96 mg for your whole batch.

Portion Control

Now, if you’re divvying that batch up into 10 equally delightful treats, each one’s got about 9.6 mg of THC. Not too shabby, right?

Remember, edibles are like a slow ride; they take a bit to kick in and last longer than other ways of enjoying cannabis. So chill, enjoy, and stay safe!

And there you have it, folks. Follow these steps, and you’ll be the master of your munchies in no time. Happy cooking, and cheers to getting every bite just right!

Now To Do The Math

Calculating the amount of cannabis per edible is essential for ensuring a pleasant and controlled experience. The key to this culinary calculation is understanding potency and dosage, which involves a bit of math but worry not! I’ll guide you through the process with a simple example, so you can apply these principles to any cannabis-infused concoction.

Step 1: Know Your Starting Material

First, you need to know the THC percentage of the cannabis you’re using. Cannabis flower potency varies, but let’s say you’re using a strain with 20% THC.

Step 2: Calculate Total THC in Your Cannabis

If you’re using 1 gram of cannabis (1000 milligrams) with 20% THC, the calculation to find the total available THC is:

Total THC=Amount of cannabis (in grams)×THC percentage×1000

For 1 gram of 20% THC cannabis:

Total THC=1×20%×1000=200mg THC

Step 3: Infusion Efficiency

Not all THC will be transferred into your infusion due to various factors, including the efficiency of decarboxylation and the fat solubility process. Let’s assume an average infusion efficiency of about 70%:

Effective THC=Total THC×Efficiency

Effective THC=200mg×0.70=140mg THC

Step 4: Calculating Per Serving

Decide how many servings you’ll be making with this batch. If you plan to make 14 edibles, for example:

THC per edible = Number of servings divided by Effective THC​

THC per edible = 140mg divided by 14 ​=10mg THC per edible

Quick Math Recap:

  • 20% THC bud
  • 1 gram used
  • Starts with 200 mg THC
  • After heating up: 160 mg
  • After mixing into your fave butter or oil: 96 mg
  • Split into 10 servings: 9.6 mg per piece

Tips for Precision:

  • Accuracy: Use a kitchen scale to accurately measure the amount of cannabis.
  • Lab Testing: The THC percentage is an estimate unless verified by lab testing, so consider this number as a guide, not an absolute.
  • Start Low, Go Slow: Especially if you’re new to cannabis edibles, starting with a lower dose (e.g., 5mg THC per serving) and waiting to see the effects (which can take 1-2 hours to manifest) is wise.

This calculation provides a foundational guideline. Remember, the actual potency can vary based on several factors, including the specific strain, the decarboxylation process, and the infusion method. Always err on the side of caution with dosages to ensure everyone enjoys their edible experience safely and pleasantly.
