I thought intuitively that might be what you meant. I can see that cannabis herb and mushrooms are plant based. Opiates are plant-based, but they are processed. Where would you draw a line in terms of that distinction? Are you referring to things which can be sourced in a relatively pure form, as opposed to things that have a chemical element or are processed?
