I am all for decriminalization, but both with cannabis and mushrooms I feel worried about the amount of "it's actually good for you!" that comes with it. I have used both (legally, in the Netherlands). As a student I enjoyed cannabis quite a bit but when I used a lot less later I did come to feel like (looking back) the usage came with some depression symptoms. With mushrooms I feel in general that they were good experiences but I've heard enough stories (first and second hand) of people experiencing long-term effects from psychedelics that I don't think it should be encouraged (at most for specific people with a therapist or so).
Personal responsibility and liberty are great but these products should come with warnings and guidance.
I think legalisation and regulation is a cure for the "its good for you" bullshit. As it becomes legal, it is easier to argue about it objectively, and there wille be also more data since people and institutions can study and research it easier.
