ill try and word this..
oz in 4 sticks = 1/4-1/8 of bud in whole or half stick respectively..
thc has an initial half life of 4hrs and a terminal half life about 30hrs. this is important in redosing for medical use but more to my point....that initial half life is whats important and the reason edibles last longer than smoked thc is due to slower absorption. not an increase in the half life or otherwise change pharmacokinetics of the drug.
so for you to feel the same effect you need to eat 3-4x what you would smoke. make sense?
so you would need to eat about half a stick at that concentration. many like 2-300mg in medium users, dank bud has roughly 20%yield.
you are correct in feeling thats alot of heat on what is widely known to be a sensitive compound. this is why edibles are often more sedating than the smoked herb even though the conversion to delta 11 makes fpr a potentially more stimulating experience.
making capsules is the most biologically efficient..with coconut oil.
if made with hash oil first you can get rid of any planty taste, really any taste at all. a simple alcohol based extract and double boil decarb is the best method
