> This is a bit more complicated than driving drunk

I'd argue no, manganese needs to be quantified in the blood stream when drunk driving imo, the state doesnt do that, but might if the doctor is called to take a blood sample having refused a breath test at the road side and/or in the police station.

Manganese has a half life of 10seconds in the blood stream, and alcohol is very good at releasing it into the blood stream for elimination and thus deficiency. When is a drunk person or a baby or toddler, not suffering from manganism which can be likened to Parkinsons?

Plus there are some gut bacteria which will produce ethanol from sugars, which is why some people always blow positive for drink driving even when they have not been drinking.

Simply measuring alcohol is not enough, and if you happen to be able to blow you own trumpet, then many musicians will know that they can do a rebreathing trick, which means they will never fail a breath test, even if they fall out of the vehicle!
