Jimmc414US appeals court declares 158-year-old home distilling ban unconstitutional
As tourists to sketchy places in Asia discovered, methanol poisoning is a real risk, even from large scale distillation. It is the quality control that matters. Illegal stills make quality control impossible, so legalisation and government certified testing can make it safe.
However, this ruling is not about alcohol, it is about dissolving Federal authority exercised via the trade and commerce clause of the Constitution.
The antidote to methanol is just ethanol.
If you find yourself drinking something untrustworthy you can at least cure yourself with a chaser of an equivalent amount of everclear.
While the treatment for methanol poisoning indeed includes ethanol, I don’t think your dosage suggestion is right. Your body would still have to process all the methanol, the job of the ethanol is just to slow down the reaction. If you suspect methanol poisoning you need the hospital, they will administer the ethanol intravenously and I think do dialysis to remove the methanol and the formic acid it metabolizes to (this is one of the toxins in ant venom)
