Oh, an argument is it?

Well, the science disagrees with you.

Our review shows that medical risks are often minimal, and that many – albeit not all – of the persistent negative perceptions of psychological risks are unsupported by the currently available scientific evidence, with the majority of reported adverse effects not being observed in a regulated and/or medical context.

The "minimal" risks being the anxiety enhanced by being on LSD. Something which is really easy to avoid with proper preparation, set and setting.

It's like you'd say "alcohol isn't for everyone" because you know so many people who just went crazy, vomited and didn't remember anything the next day in a massive hangover. Because they didn't know how much or how fast to drink.

But if there's someone who knows to pace that person and occasionally offer them water (and make sure they've eaten before start drinking), then you can be rather sure that they'll have a pleasant evening and little to no hangover.

It's a tool. And like tools, you need to know how to use it. And then you need to use it responsibly.

Nothing in excess
