You will never be able to tell how you wouldn’t change had you not tried these. But I feel the same as you and I still feel the impact of my only LSD trip I had over 15 years ago like it just happened over the last weekend. However, I know someone who tried LSD for a year here and there every other weekend and I could tell that they incurred some dammage in their brain. They’ve grown in a way but feel fragmented and a bit broken in some other way.
