100% ethanol is generally made by a molecular sieve and it does not require any sort of poison. I have drank it before, and it is very strong of course, but no more dangerous than everclear. If there is any poisonous chemical other than ethanol in it, it is by definition not 100% ethanol. You can actually trivially make your own by purchasing molecular sieve material online. Of course I would never do that besides distilling is illegal :) Fun fact though: it’s not 100% ethanol for long after you open the bottle because it will absorb water from the air until you hit the azeotropic limit.
