Well... i think you can measure the dose you would need.
If you were to smoke the bud and stems you put in it, how many doses you would get from the amount you put in the green dragon?
The number of doses is the fraction of the green dragon that contains the amount of weed you would usually smoke. For example:
Lets say the amount of weed/stems you put in it would be enough for smoking 6 times. So, if you were to drink the amount of g.d. equivalent to this, you should drink 1/6 of the total amount of g.d. you got.
As drinking weed is not so efficient as smoking, i always drink more than smoke. Usually i drink 1.5-2x the amount i would smoke. So, if you were to double the amount of g.d., supposing the same ratio used before, you should drink 2/6 (or 1/3) of the total amount of g.d. you got.
I hope my explanation dont be too much confusing (im :stoned, good luck, and tell us how it was! :thumbsup:
