In my experience you get some no matter the method now there are somethings to do to lessen the amount transfered and yes 1 is drying , now I've seen a guy use water as chlorophyll is water soluble and butter/coconut oil isn't so before the butter cools you pour it into a small pot/container and you can set it in fridge for it to solidify and simply pull it out. Now as for the ethonal extract can be vaped or eatten I will say from experience with fresh material I would run 2x and then do a full soak for 15 to 20 mins which after drying out and looking under a scope 90% of trics are removed I do something similar still and I love it the only thing I would like to experiment with dry ice and a sub zero freezer but I won't be able to till I move. I also would say if making a smokeable product do not heat it as not only will you loose terps but the taste can be quite ruff now if making rso or eddibles it's much less an issue.
