I decided to start tracking dosages before and after vaporization. Does anybody else do this? I don't recall seeing much on the subject, so I thought I'd start weighing loads before and after vaporization just for shits and giggles. Feel free to play along at home if you have a scale that measures to the .01g. Round 1. Girl Scout Cookies - Cloud @ Noon - Starting weight .22g - ABV weight .17 - Extraction efficiency 22.73%. I've got the spreadsheet started already, so no one can talk me out of it now.
