VERY cool thread.
Do a test. Take some lettuce and grind it up (lettuce is used as the only 'standard' iin chlorophyll determination, although even THAT is kinda shaky lol). Treat it the same way. You are testing to see whether the green glow is from a non-drug component commonly found in plants, such as a pigment.
Chlorophyll is commonly extracted in a mixture of acetone and water in lab analyses, just FYI.
