This replaces the widespread use of methanol and similar products which are poisonous (yes even if you call the product "meths" it probably isn't methanol in the EU today). The rationale is that poisoning people is not an appropriate reaction to attempted tax avoidance. Alcohol is only "denatured" because booze is ta…

I don’t really see the point of risking poisoning people as a way of dissuading tax dodging especially when alternatives exist.
