when i have made hash oil (honey oil) treats i typically use one tenth a gram as a dose but brick hash (cold water extraction or silk screen dry extraction) is about half the potency and thus means double it. These doses are for an avg. smoker. My personal treats I usually triple or quadruple the dose it depends on what your price to produce the hash is and if youre planning to profit from it or are just looking to have a real hash experience. how you feel about the taste of hash and what your tolerance is or the people who will be partaking in the treats tolerance is. There are many factors that come into play.

if the herb reveals you to yourself then hash will really do the trick
