We’d probably see higher rates of it in societies that used those drugs often, which afaik we don’t
specifically mescaline, mushrooms, ayahuasca/dmt, and weed have all been used by humans for a long time, and I haven’t heard anything about higher rates of neurodivergence in those societies
i could see mdma having an impact like that though, since it’s much riskier than psychedelics and weed (iirc it can be cardiotoxic, neurotoxic, and much more likely to be addictive than those) and we don’t have historical/traditional users of it to look at
