>The challenging or scary part for me at least is when you rely on your own mind as a place where you can reason about things and then you start to worry if your ability to do that has been compromised.

As someone who did LSD many years ago and was deeply moved by it, the scary part wasn't worry that my brain had been compromised by LSD. What was scary was that suddenly I was aware that perhaps my brain had been compromised all along, and I just didn't realize it until I did LSD.

If it does anything, LSD (at least at moderate-high doses) tears away the ego and strips away the unconscious filters through which we view reality. It can be a profoundly humbling, illuminating, and terrifying experience, all at the same time. Use with caution.
