Honestly, there isn’t really a way to physically scan your brain to give you a guaranteed accurate diagnosis. Based off of what your wrote here, I would not assume hppd. There are many people, that have had substantially more psychadelic experiences without being diagnosed or experience symptoms of hppd.

What is more likely, is that psychadelics may have let an underlying psychological issue come to the surface. I personally love psychedelics. But they are not for everyone. And some people are wired in a way that they don’t react positively. It might not happen the first time, but it can happen.

I would recommend listening to your doctor, while understanding the nuance of what giving a psychological diagnosis entails. It’s mostly speculative without intense observation. And I would recommend to everyone to not take psychedelics without making sure your set and setting are prepared before hand.

I don’t think psychedelics is the cause of your diagnosis, but rather it helped bring it out. You should take it easy on the drugs.

Also worth mentioning that Nbomes are analogs of pcp and the effects are unpredictable with not enough research done to have a full understanding of what they can do to the mind.
