From an unexpected conversation with some younger people not long ago (though not this young), they may have just switched to LSD.
And those should learn something from Syd Barret's life
Could had been a millionaire rock star, women, expensive toys, children. He could had everything for the rest of his life. But he choose LSD. As a lot of people claim, LSD is a cool and harmless funny drug, right?.
His life instead was: living in his mum house since 24 Yo, with his brain like a car crash, and all the time in the world to think on his boy room about how he managed to mess up his life so badly.
So thanks, but no way.
Those that can, do not agree that LSD was causative.
Syd was not the only person doing LSD in the 1960s, and if your argument boils down to "people with life-long major neurodivergence, who are living multiple years of extraordinarily stressful life, should not do huge amounts of psychedelic drugs" ... then OK! That's a good rule of thumb!
But the vast majority of people are not latent schizophrenics. And the vast majority of drug users could not approach Syd's consumption in quantity or duration.
So an argument from the same data is that occasional or even moderate use of LSD by almost every adult human, is perfectly safe.

Reframed: Every adult can make their own decisions about their personal level of risk tolerance. Hopefully the decision will be an informed one. Syd Barrett can be a huge terrifying red flag, or a bright illuminating green light, depending on the decisions you've made.
On one extreme of risk tolerance, you'd never leave the house. On the other extreme, (with some bad luck, some excellent luck, and a great deal of effort and resources!) you might approach Syd Barrett's lifestyle. Neither extreme is appropriate for most people.
