> Your consensus is only general among irresponsible psychonauts that were lucky enough in the past.
You're using the words "irresponsible" and "lucky" here to trigger an emotional response that these kinds of risks are anything but rare, which simply isn't supported by any data. I "irresponsibly" crossed the street today. Am I "lucky" I wasn't run over by a bus?
> The general consensus is to use psychedelics only as part of a therapy under supervision by a medical expert.
And the general consensus is to always consult your doctor before beginning any kind of exercise program. This is a standard CYA position adopted by the medical profession.

Nobody is denying that mental health problems are real and prevalent. The link between psychedelics and the onset mental health problems is what's at issue. 15%–20% of the US population tries psychedelics in their lifetime, and 5% of US adults experience a serious mental illness each year. Mental illness is clearly a huge problem with or without psychedelics, and the zeitgeist of research into these substances in the past decade has been almost universally uncovering the ways they can be used to help the situation.
> How does this reduce the danger of psychedelics in any way ? It increases the danger because you do not know in advance if the drug will trigger your mental disorder that you do not have yet.
Many people have the underlying structural changes in their brain that indicate an imminent onset of symptoms of schizophrenia. In cases like this, it's theorized (but again, data is scant) that psychedelics like LSD can be a triggering event that brings about an onset of symptoms, but ones that were all but inevitable anyway. That's not to say that the loss of even a month or week of sanity isn't tragic, but I've seen very little in the way of evidence that occasional LSD use in particular is substantially more risky for the average mentally healthy person than any other recreational activity one might engage in.
