The Place of Pot in my Practice?

Do entheogenic substances (https://en.wikipedia.org/wiki/Entheogen) like cannabis (https://en.wikipedia.org/wiki/Entheogenic_use_of_cannabis), magic mushrooms, and Amazonian Ayahuasca brews (natema, caapi, Syrian rue) -- which seem to stimulate our endogenous DMT, "The Spirit Molecule" (https://youtu.be/LtT6Xkk-kzk) and pineal gland -- have any place in meditation or spirituality?

Talk is cheap, so we'll talk about the possibility of organizing a real life Plant Ceremony. Psyche-delic means "mind-making" (reality-creating, matrix-imagining), and the plant world has much to teach us. Wait, what does the Dalai Lama have to say about this? (https://youtu.be/vnQr2AqVpIU).
