&gt; I am saddened that after reading stories like this one, people remain skeptical of fortifying water with Lithium.<p>You start with that, next thing you know you&#x27;re crop-dusting Miranda with G-23 (and we all know how that went).<p>More seriously, lithium has significant side-effects, lithium toxicity can occur both acutely and chronically, and lithium toxicity isn&#x27;t always much higher than therapeutic doses (especially as it&#x27;s compounded by sodium depletion). And there&#x27;s a significant risk of fetal toxicity.<p>Normalising medical lithium use sounds like a great idea (especially as part of a wider normalisation of treatment of mental distress and illness), but it doesn&#x27;t sound like the best substance to spike water with.
