The entire point of categorizing them is to answer questions around:
- Should they be sold to take recreationally, like tobacco and alcohol? Should there be limits, like tobacco packaging and taxes, or rules similar to drunk driving?
- Or should they only be prescribed by doctors for mental health reasons, and not allowed recreationally or in religious ceremonies?
- Or should there be exceptions for certain religious ceremonies as well? Is this open to anyone (so Catholics can invent a ceremony) or only ones that have traditionally used it? Does it require licensing or authorization?
By categorizing them, we come to answers on these questions. If they fit into existing categories, we don't have to write many new laws except to state the categories. Or if we decide they don't fit into existing categories, we come up with a new category with its own set of answers and new laws to write, but part of this whole process is determining if that's necessary or not. And even if it is, the name of the label may not be "psychadelics" because we realize there's another set of non-psychadelic compounds that make sense to be included as well (e.g. empathogens like MDMA).
