Many cannabis consumers do not know the correct flower to oil ratio (for their own personal dose) and may use too much cannabis, or too little, in their oils or butter. The endocannabinoid system is highly individualized, and what may work for one person, may not do anything for another.
Not knowing your own flower to oil ratio can have an adverse effect on future cannabis edibles consumption and experiences as well as becoming a somewhat confusing process for those who are new to cannabis or cannabis edibles.
We will be approximating an 80% THC infusion rate into whatever fat or oil you are infusing during this article. This approximation is somewhat high, however, it is better to overestimate when you are consuming cannabis edibles and a flower to oil ratio that suits you. In addition, different fats and oils produce different results therefore, experimentation with different oils, fats, and other substances such as flour, sugar or alcohol are incredibly important.
We will also be infusing 2 cups of oil (500ml) in total for these examples and making 20 cannabis cookies with 1/4 of a cup of the cannabis-infused oil. Storing your cannabis correctly will also ensure potency for your oil, or infusion.
These variables are incredibly important when determining a personal dose for edibles. The complete list of variables you need to consider when approximating the THC content of homemade edibles can be found at the end.
Flower to Oil Ratio: 5 Grams of Cannabis to 2 Cups of Oil
5 grams of 20% THC cannabis = 5,000mg x 20% THC = 1,000mg of total THC
Multiply 1,000mg of THC by 80% (The approximate absorption rate of THC into the oil) = 800mg THC
Divide the 800mg of infused THC by the amount of oil you will use, as well as the number of servings you will produce.
For example, If you were to make cookies using 1/4 of a cup of this oil, they would contain 100mg of THC in total. (800mg/8 = 100mg per 1/4 cup of oil).
Furthermore, if you were to make 20 cookies, they would contain approximately 5mg of THC each. (100mg of THC divided by 20 cookies). These cannabis cookies are perfect for those who are new to cannabis edibles, or, have a lower tolerance. Your own endocannabinoid system will play a large role in how your body reacts to cannabis.
Flower to Oil Ratio: 10 Grams of Cannabis to 2 Cups of Oil
10 grams of 20% THC cannabis = 10,000mg x 20% THC = 2,000mg of total THC
Multiply 2,000mg of THC by 80% = 1,600mg (Infused) THC
Divide 1,600mg of total infused THC by the amount of oil you use (1,600mg/8 = 200mg of THC per 1/4 cup of oil), as well as the number of servings you will create.
20 cookies, made with 1/4 cup of this oil = approximately 10mg of THC in each cookie. (200mg of THC divided by 20 cookies)
Flower to Oil Ratio: 15 Grams of Cannabis to 2 Cups of Oil
15 grams of 20% THC cannabis = 15,000mg x 20% THC = 3,000mg of total THC
Multiply 3,000mg of THC by 80% = 2,400mg (Infused) THC
Divide 2,400 of total infused THC by the amount of oil you will use (2,400mg/8 = 300mg of THC per 1/4 cup of oil), as well as the number of servings you will create.
20 cookies made with 1/4 cup of this oil = approximately 15mg of THC in each cookie. (300mg of THC divided by 20 cookies)
Flower to Oil Ratio: 20 Grams of Cannabis
20 grams of 20% THC cannabis = 20,000mg x 20% THC = 4,000mg of total THC
Multiply 4,000mg of THC by 80% = 3,200mg (Infused) THC
Divide 3,200mg of total infused THC by the amount of oil you will use, (3,200mg/8 = 400mg of THC per 1/4 cup of oil), as well as the number of servings you will create.
20 cookies made with 1/4 cup of this oil = approximately 20mg of THC per cookie. (400mg divided by 20 cookies).
The five variables when considering a flower to oil ratio are:
- The Amount of Cannabis Used
- The THC Content of the Cannabis
- The Amount of Oil Infused
- How Much Oil (or Other Substance) You Will Use
- How Many Servings You Make
The absorption rate for THC into fats and oils is not 80%, however, it is better to over approximate your cannabis edibles and potency when it comes to the flower to oil ratio. Ensure your cannabis is stored properly.
Flower to Oil Ratio – Blank Equation
Feel free to use our blank equation below to work out the best flower to oil ratio for you personally.
Step One: The Amount of Cannabis (in mg) divided by the THC content. This lets you know how many milligrams of THC, in total, you have within your cannabis.
_ Grams of cannabis multiplied by __ % THC = ____ (Total Amount of THC)
Step Two: Multiply the total amount of THC (Step One) within the cannabis by 80% (An approximate infusion rate)
_ MG of total THC multiplied by 80% = _____ (This represents the total infused THC)
Step Three: Divide the total amount of infused THC (Step Two) by the amount of oil you will create and use, as well as the number of servings you will make.
We have to use an example in this part of the equation, but, it makes it easier to see the working. For this example, we have made 2 cups of total cannabis oil and we are using 1/4 of a cup in our recipe.
(Total Infused THC) Divided by 8 (2 cups of cannabis oil divided by 1/4 of a cup)
= The total amount of THC in the entire batch of cannabis edibles
Divide this by the number of servings created.
Total THC in the entire batch of edibles ___ (THC) divided by _____ (Servings)
= The approximate amount of THC per serving.
These equations are only an approximate wayto measure the THC content of cannabis edibles as well as a suitable flower to oil ratio. The only way to truly grasp your own personal dosage when it comes to cannabis edibles is to experiment by starting low, in terms of THC content, and taking it slow, in terms of how much you consume.
Cannabis edibles affect everyone differently and the endocannabinoid system varies greatly from one individual to another.
