It is. Activated carbon is used to treat diarrhoea, you basically swallow a chunk of carbon that absorbs any moisture it comes across

Don't lick carbon nano tubes or buckyball. Also in general carbon powder can be a particulate inhalation issue.

The table is about licking specifically. It’s not a breathability table. Just so that is clear.

I assume if it's getting anywhere near your mouth you'd also be breathing it but aside from that, ingestion is also a nogo.

The ingestion/breathability table might be more restrictive. Like, elemental Sulfur is ~~perfectly fine~~no actually it’s not fine— but probably unpleasant to lick. Contact dermatitis likely but not life threatening—just one lick, ok; promise no more? ;)

Breathing elemental Sulfur is also going to result in contact dermatitis -inside the lungs. Which is going make a really bad day.

Activated carbon is also used in water treatment to remove taste/odours and many organic pollutants.

“organic pollutants” are made of carbon too

[–] MotoAsh@lemmy.world 5 points 1 month ago

Not moisture but reactive molecules. (I mean, many forms probably do still absorb a good bit but) I forgot the exact chemistry but "activated" means chemically reactive. It binds with all sorts of reactive molecules, like toxins and many other things.

Diarrhea is also mostly carbon.
