Nice submission. Brings back memories of making alcoholic drinks from expensive spectroscopy grade ethanol. We never dared hitting the deuterated ethanol for NMR purposes...
Just in case the sarcasm wasn't abundantly obvious, the precise term used was simple asphyxiant with the following regulatory meaning[1]:
>> Simple asphyxiant means a substance or mixture that displaces oxygen in the ambient atmosphere, and can thus cause oxygen deprivation in those who are exposed, leading to unconsciousness and death.

Always remember to drink in (neutron) moderation!
For example, here's a Derek Lowe article about deuterated drugs (not ethanol):
- "So a well placed deuterium (or two, or three) can actually have a significant effect on how long a drug will circulate in the bloodstream, by slowing down the liver's clearance mechanism."
