That's according to his brother Dennis and other close friends who've known all this time. Terence suffered a devestating trip in 1988 and never really recovered by the sounds of it; the details are not really known except by his partner at the time, but basically the mushroom that had been his teacher turned on him, forcing Terence to confront his self and this plunged Terence into panic. He used DMT and Ayahuasca only on occassion after that too. This is significant because from 1988 until his death he continued to lecture and put on his Terence persona of '5 dried grams in silent darkness' whilst actually internally struggling with the experience he'd had.
These revelations will be in Dennis McKenna's book coming out soon, and long time friend Bruce Damer gave a reading of some of these snippets, as well as his own thoughts on Terence, in a podcast in the Psychedelic Salon. This has since been removed at the request of Dennis (something about the book), but the podcast is available here on youtube.
I highly recommend listening.. it might shock you to know that Terence was actually just a human being like everyone else
