What’s the best way to dilute THC syrup?

Getting the right answers in your cannabis journey can be tricky. But with The Cannigma’s Ask the Expert, you can find questions from readers like you, answered by a real cannabis pharmacist. 


I have THC syrup – 1oz, 100 mgs THC – (I thought I’d try it), and it’s far too thick for how I want to use it. 
What’s the best way to dilute the syrup?

Many thanks,


Regarding the dilution, don’t overthink this one. A syrup, by definition, is a water and sugar combination. In this case, you can just dilute the known amount of syrup with an equal part of water to cut the concentration in half.

For example: you currently have 100mg/ 1 oz which is the same as 100mg/30mL 

Therefore your current syrup is 3.33mg/ml.

If you wanted to dilute the syrup, you could add 30mL of water (or any other liquid) to make 100mg in 60ml of fluid =1.67mg/ml

If you wanted a cleaner number— you could add 20ml of fluid to your existing syrup to make a total of 100mg in 50mL = 2mg/mL

Remember that dilution will change the taste of the solution as well.
