Terence McKenna would be stoked to learn his psychedelic explorations were being studied scientifically and medicinally.
He said Ayahuasca makes a person sick for a long time. Days, I think he said. Vomiting, diarrhea, nausea, abdominal pain, and headache, I think.
I recently took a young guy close to me with severe and drug-resistant depression to get ketamine treatments administered by an anesthesiologist. It was a breakthrough for him.
Ketamine is probably more effective than Ayahuasca for treating depression with far less severe side effects.
