Once you see the world through the lenses of mushrooms or LSD, you can't unsee it. I think it opens your mind, helps you question your assumptions.

I've seen ayahuasca helping people to get rid of alcohol addiction.

You can probably achieve similar transformations by meditation or reading books, but if you are one of those people who don't listen to advice and must try everything for themselves, psychedelics will be faster way to get there.

So I think it can be very powerful tools, but I'm sure there is some cost to it as well:-)

Why governments don't like it, I have no idea, but another positive signal for psychedelics:-)
