I have no weed! What a predicament eh? So how am I high?
I foresaw this coming with the relative tinyness left in the bag, so what did I do? Well I pulled out a 2 year old bag where I happened to have thrown any stems I may have gathered over the time. I threw about 40% of the stems into a bottle, put isopropyl alcohol up to the level the stems reached, shook for 2 minutes, and strained the then greenish liquid into a dish.
Took a hotplate, put a pot of water on, set the dish with liquid on top, and waited for it to evaporate.
