2/2 toxic for each other, while Talithi breath cabon monoxide in & oxygen out (not on a one to one scale) they would be perfect as companions in settlements or onboard ships but in a cruel twist, we & them exhale particles that, if they go into the lounge of the other species, will react with the biological system & produce a byproduct that intoxicates them & is hard to get rid of. For this reason masking up while in the room with Talithi or Terrans is a given social norm. No other species has this reaction to Talith or Terran breath. A sign of deep trust between both species is to lift the mask for a short period while having close contact. In a filtrated environment this isn't a problem but in non filtrated environments or closed cycles it gets nasty quickly.
Kira has some bad memories of waking up with a full intoxication via Talithi breath including 2 days at a hospital, so if it is intoxication it's beer.
