Yes, it’s good to be skeptical when big claims are made. I have had one (heroic) experience of LSD and while it was one of the most peak experiences of my life I cannot say if it was positive or negative just that it was extreme. Fixes for some will come at a price for others in my opinion. As my friend said while looking me deep into the eyes at the end of our trip together “It’s not exactly what you would call recreational is it?”.

Also I’d add that older minds find these experiences much more difficult to process/deal with. I believe research is good but can it be used if 5% of people have very negative reactions?
