Thankyou, yeah look at prohibition and how bootleg liquor sometimes contained methanol which can cause blindness when the alcohol isnt distilled properly and methanol has a lower evaporating point and thus is one of the first products of the process that makes it to the end of the process. Other things like lead solder used in the copper fittings when building it and using things like car radiators as the condenser and the mash containers being left to ferment in the woods with mice and other animals falling into the barrels and dying. So yeah in terms of regulation it definitely helps to have laws in place for companies who give two shits about having a legit business
