People should absolutely be able to consent to do something that will hurt them.
However, it should be informed consent.
If you don’t have the correct information, you cannot give informed consent.
I read it not as “You shouldn’t tell people about Ayahuasca” but “You shouldn’t advocate that people use this thing unless you can give enough information so that the consent will be informed consent, and there hasn’t been enough study to provide that amount of information yet.”
