Edible Dosing Calculator
You can use flower or any cannabis concentrate, as long as you know the THC/CBD content.
How strong is your cannabis?
Edibles are an increasingly popular way to consume cannabis - they’re discreet, long-lasting, and produce a different, often more intense “high” than smoking or vaping. Depending on where you live, you might be able to buy pre-made edibles. If not, you’re going to need to get down and dirty in the kitchen.
But how much weed should you use in your first brownie batch? And how many brownies should you eat? With a couple easy inputs and measurements, this calculator can estimate how strong your edibles are going to be.
How to use the infusion calculator
If you’re making your oil from cannabis flower, you’ll need to start with the first phase of the calculations – the infusion calculation. If you’re starting with a labeled cannabis oil you can skip this step. Many products on the market will contain a laboratory-confirmed concentration on the packaging already and always look for the certificate of analysis.
Infused oil is often about 20mg/ml, but it can vary widely from product to product. It can even be hard to understand the concentration of many products due to a high variability in labeling standards; some show cannabinoid content in drops, others in full droppers, and others still use percentages.
If you’re making your own infused oil, you’ll need to know the approximate cannabinoid concentration of the flower in order to calculate oil potency. That total cannabinoid amount can then be used to determine how much cannabinoid will be in each milliliter of oil that you’re infusing. With that number, this calculator is designed to account for loss during the decarboxylation process, and also account for some loss in the infusion process. Variation in temperatures used and time during decarboxylation and infusion can have a major impact on cannabinoid content.
There are numerous factors that contribute to the variability in final concentration of homemade oil, but none are completely avoidable and therefore there will always be some loss of cannabinoids in the infusion process. The true scale of the expected loss during these steps is going to be variable based on the processes used, so this calculator estimates these losses at 20% of the total cannabinoid (THC and CBD) content.
How to use the edibles dosing calculator
The second portion of the calculator can help simplify portioning out your edibles, ensuring that you add enough infused oil to the recipes to deliver the desired dose in each edible.
To be clear - no edibles calculator will be perfect; there are too many variables involved. Without using a tested product, this math is only an estimate and can vary widely based on factors like moisture content, oven variability, differences in cannabis grind, and the amounts of oil and cannabis used.
Can I use distillate or concentrate instead of cannabis oil?
Absolutely! Distillate or concentrate can also be substituted for infused oil, but keep in mind that these are often highly concentrated compared to oils, and are harder to accurately measure. Also, it’s easy to reduce the total THC in a recipe by reducing the amount of infused oil and substituting with regular oil.
With the help of this calculator and some starting lab values, you can figure out the right amount of cannabis to deliver the experience you are looking for.
