i also don't think i knew in any concrete way about any risks and if someone had told me i would've been like "that probably won't happen to me" and i would've been right
(but otoh a friend of mine went into a yearlong depression or something after an acid trip so i am now, at least, more aware that the risks exist and are real and worth looking into 😬 i would not recommend acid to someone with a serious trauma history, eg)
