  1. Hi! I'm a philosopher/scientist very interested in HPPD. Could you please post the response that Grof foundation has sent you? (I know this thread is very old, but I thought it won't hurt to try) It is very importaint to me, because I'm surprised that HPPD is so rarely mentioned even in very high quality psychedelic scientific literature. It would be great to know what Grof foundation state about this issue. I'm sometimes attending to conferences talking about psychedelics and I never forget to mention the risk of HPPD and the fact how little we know about this problem. That's why this answer might help me to better understand the issue and share it with fellow scholars. Best regards and I apologise for necroing this thread, Invoker
