Thank you for sharing that. That's a valid concern- people trying psychedelics on their own also run into the risk that what they're getting is altered, not what they wanted at all, or unintentionally taking a dose that will bring them bad outcomes. Even with cannabis, back when it was completely illegal, I knew people who would sometimesb unknowingly get their hands on batches that had been laced with something else and end up having wildly unpredictable (and sometimes frightening) experiences.
