In general, you can write off pretty much any idea that involves poisoning children as unethical. That death tolls from the [opioid crisis](https://en.wikipedia.org/wiki/Opioid_epidemic https://en.wikipedia.org/wiki/Opioid_epidemic) have been rising is a problem that people've been trying to mitigate, not further. It is a bit strange to consider that we still do poison alcohol to prevent, say, people from drinking mouthwash (https://en.wikipedia.org/wiki/Denatured_alcohol https://en.wikipedia.org/wiki/Denatured_alcohol): > Denatured alcohol, also called methylated spirit (in Australia, New Zealand, South Africa and the United Kingdom) or denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage recreational consumption. Unfortunately, despite a widespread cultural understanding that it's dangerous to consume denatured alcohols like mouthwash, some folks still do (https://en.wikipedia.org/wiki/Surrogate_alcohol https://en.wikipedia.org/wiki/Surrogate_alcohol): > Surrogate alcohol is a term for any substance containing ethanol that is intentionally consumed by humans but is not meant for human consumption. [...] Most people turn to these as a last resort either out of desperation, being underaged or being unable to afford consumable alcoholic beverages (with homeless alcoholics) or due to lack of access to drinking ethanol (for example with prison inmates and individuals in psychiatric wards).
