Interesting article. How believable it is remains debatable, but the girl that cured her bipolar is very peculiar. If it can really cure this disease there's hope for many people around the world.
Also, I don't really agree with those scientists' "lethal dose" estimate. Many people have taken more than 17k mcg in recorded history and have turned out fine. Robert Hunter talks about his accidental 250,000mcg trip on a ball in his correspondence with Terence McKenna. Many people have spoken about the effects of taking a thumbprint, which is FAR more than 250mg. It's just not a believable estimate, not with the subjects being in perfect health and mental condition. There might be many other factors that could make a dose like that lethal for someone, but in an all things equal scenario, I doubt it can kill a healthy individual.
Knowing what more than 1200mcg feels like, I wonder what it is to take a dose so many orders of magnitude greater. Is there an effective threshold, past which it becomes pointless to take more? Or does the journey get crazier with the dose, with no cap at all?
So many questions, not enough brave people to seek the answers.
