I've made stem tea before, but I'm not sure if it worked as I was already ripped when I drank it. But if you're making tea from actual buds, how much does it take and how should it be prepared?
as far as I know THC cannot be readily dissolved in water, so unfortunatly weed tea wouldnt work. Other cannabinoids may be water soluble, so you may experience a slight stone, but its prolly just a waste of weed to try it... I'm sure if you got some marinol (synthetic THC) some how and put it in your tea it would work, but other then that I dont think it would work.
or one method that is reminiscent of the traditional indian drink bhang, dissolve the thc in strong grain alchohol first, then mix that into whatever you want the tea to be in, and then heat it up so that the alchohol mostly evapourates, leaving the thc in the drink dissolved in whatever small amount of alchohol is left.
