Explains how to calculate the correct dose when making edibles using marijuana.
Dosing is very important when making edibles. You can easily ingest too much THC if you don’t calculate the concentrations in your recipes.
Noone has ever died from marijuana. But if you take too much you might have what is known as a bad trip.
For an funny example of a bad trip and taking too much edibles, watch this video of a guy who called 911 after not dosing correctly:
Knowing how much THC is in your bud is the first piece of information you need to know to start calculating your dosing for edibles.
A laboratory analysis will tell you exactly how much THC is in the bud you plan to use to cook with. But since you probably do not have laboratory to analyze your bud you will have to make a reasonable estimate.
Most average bud is around 10% THC. Exceptionally strong bud is 20% or even a little higher.
You can smoke some of the bud to gauge its strength before using it in cooking. Decide for yourself if it is low grade, average, above average, or knock your socks off strong!
Commercial edibles are usually labelled in milligrams of THC. You can estimate the milligrams for your home made edibles using the averages discussed in this article and some simple math.
1 gram is 1000 milligrams. Since average bud is 10% THC, 1 gram = 100 milligrams of THC.
For a 150 lb individual with some experience with marijuana, a single edible dose should be 1/4 to 1 gram of average bud.
A dose of 100 milligrams of THC (which is the standard amount for edibles in the state of Colorado) converts to approximately 1 gram of average bud (10% THC).
In order to figure out how much bud to infuse with your oil or butter, you must consider the recipe because different recipes require different amounts of butter or oil and result in different numbers of servings.
In our recipe videos, we include guidance on dosing. Please watch the two videos below.
In the first video we make smoothies. The recipe creates 2 smoothies, or two servings. Our goal is to make the smoothies approximately 100mg THC. Remember that 1 gram of bud is approximately 100mg of THC. We infuse 1/4 cup of coconut oil with 2 grams, so that when the cannoil is split across 2 servings each serving will be approximately 1 gram, or 100mg of THC. If you wanted to lower the dosage, you’d simply lower the amount of bud you infuse with the oil used in the recipe.
In the 2nd video we make muffins. The recipe requires 3/4 of a cup coconut oil and produces 12 muffins. Since we wanted the muffins to have 1/2 gram of bud each, or 50mg of THC, we created the cannaoil by infusing 6 grams with the 3/4 of a cup oil required by the recipe.
By understanding how to calculate dosing you can take many regular recipes that use oil or butter and convert them to be THC infused recipes.
If you are using trim it is reasonable to assume it is at half the strength of average bud or less. Therefore you would need to use at least double the amount of trim as you would average bud to extract the same amount of THC.
Trim can foul up the taste of your edibles since you have to use more plant material for the infusion, so we don’t recommend trim if you can use bud or hash instead. On the other hand, using trim for edibles is a great way to not waste the trim by throwing it out.
If you plan on using trim, make sure it is sugar trim (the leaves have some white trichomes). If there are hardly any trichomes on the leaves, you aren’t going to get very potent cannabutter or oil.
The potency of hash can vary a lot. 1/8 of premium pure hash can be enough for a single serving (100mg THC). But if the hash you are using has a lot of plant material mixed in and is not strong, you may need to budget 2 grams for each serving.
Without a lab test, testing the material yourself is the best way to calculate strength.
