That's an almost impossible question to answer. Let me explain why, there are a whole bunch of factors that go into finding the right dose.
First of all tolerance, this makes a huge difference from person to person. Are you an experienced person or is it your first time eating an edible? You understand that this makes a very big difference in the right dose. There are also a number of other things at play such as weight, height, age, how strong is your strain, and so on.
The "recommendations" therefore range from 1 to 100 mg of cannabinoids. Personally, I would say a dose of 15 mg is quite appropriate to start with, look further from there. Do you make the next serving stronger or weaker?
