You can make either hash oil or a drink called the 'green dragon' from stems and old stalks
'Green Dragon' Vodka and stems. leaves, stalks, buds etc. just throw it all into a glass jar, keep it in a cool dark place, shake it once a week, after about 1 month this stuff will de drinkable (it must be mixed w/ Pineapple juice!)
P juice has enuf citrus in it to cut the weed taste (which can be quite bitter!) 2 parts g' dragon to one part p juice. do a shot or two wait about 3-5 minutes to feel the buzz, enjoy!!
p.s. the better quality the shake that goes into each of these (oil or drink) the better the taste and potency! (Duh!)
