At an Entheogenic conference a Speaker stated that in his time extracting and testing DMT in Plants that he 'Would go and take samples from plants, and that one day the plant could have little or NO DMT content, but on other days not too different to the last The plants could have lots of alkaloids'
He said it could have just been the weather or his intentions, and That the variables to take in account were endless!
"Given enough Time even Hydrogen starts to wonder where it came from, and where it is going"
