I would not say psychedelics are *the* cure. However, I took them a lot when younger (primarily LSD and MDMA) and found they had a major beneficial effect on me.
Before I took them I was largely stuck in one mode of mental functioning (ie, logic); afterwards, I was far more flexible, socially, emotionally, even physically.
I would not blanket recommend them to everyone, there definitely are dangers...however, these dangers are quite well-understood and can be largely avoided if you research the subject thoroughly before taking them (which I did).

"Believe me a bad trip is one of the worst experiences you can have. And when you have one you are stuck there until the drug wears off."
Actually, if it's LSD, you can largely bring yourself down with niacin (vitamin b3). I've tried it, it works. It's physically unpleasant for a short while (a sort of burning, tingling feeling in the skin) but far better than several more hours of bad trip.

"Psychedelics were experimented with in the '60s. They only were useful in trace dosages that were no good for recreational use (since that seems to be what you have in mind), and they only worked for a few weeks before their tolerance skyrocketed and it quit working at all."
I've read quite a lot about the experiments in the 60's but I've not heard of this, do you have a reference for it? The only experiments I'm aware of relating to LSD and autism were with classical (severe) autistics, who showed significant changes in many cases, but only for the duration of the drug's immediate effect.
Also, I would point out that unlike most drugs, psychedelics generally do not need to be taken on an ongoing basis; a few sessions gives the user a new perspective which they then slwoly integrate into their day-to-day life.
Again, I am not trying to advocate psychedelics for all; however, I do think they have a place in psychotherapy and it is a great loss to society that professionals are not allowed to use them. Nowadays, I am more enthusiastic personally about yoga and meditation as self-medication techniques than drugs; however, when I tried them before I had taken psychedelics they did nothing for me, I didn't understand what I was trying to do. Psychedelics "opened the door" for me, and since then I find myself increasing able to "get there" under my own power.
I am a qualified psychologist by the way (BSc 2:1, Hons).
