A sitter isn't going to save you from a lifetime of HPPD or visual snow.
There's at least anecdotal evidence of that

So it's all about you.
No, it really is about everyone else and not forfeiting their chance to experience something new by dissuading them with misinformation or some cautionary tale about an isolated fate that possibly was not at all about salvia.
I didn't bumble into salvia with no information on hand. I went there after reading about it, its effects, potential risks, chemistry, first-hand experiences etc. for years. A lifetime of side effects is not something associated with salvia.
