Posted: I think that you yourself have identified the problem. Using edible products with cannabis you cannot know the total amount of THC in it. I have always been strongly opposed to such things, even for fun. If you had in mind to achieve a therapeutic effect, then I recommend using the CBD oil - https://purekana.com/collections/ This medicine does not have psychoactive ingredients and can be used as an anesthetic or hypnotic. Be careful when trying something new!
