The liquid is going to exert positive pressure as it fizzes and fill an area it is in with as much CO2 as it was holding. Eventually this will push the concentration way up as it is going to displace oxygen and eventually near 100%. If the volume of the vase is only capable of holding around a liter of airspace in a large vase (rough estimate that changes a lot based on the vase) and the average human breath is around 6 liters then you have a concentration of almost 17% in that one breath. That's really rough math based on eyeballed volumes but even getting more conservative, if the space is a half a liter (a very small space) you still have 8%. Now lets say that half of the CO2 is lost in the pour (not going to happen) even at a half liter airspace and half the CO2 you are pushing 5%. That's not even taking into account that you will be inhaling CO2 through the entire draw as it gets released from the soda with agitation.
I have not done measurements on this but it's some simple math. It's also a terrible idea. Avoid inhaling CO2. It's more toxic than you think. 5% is an astoundingly small amount. You only need to inhale 1/3 liter in one breath to peak over 5%.
again i am not suggesting filling a base fully with soda is a good idea. while i agree with your numbers there is one flaw, the carbonation takes a while to come out, even when being agitated all the CO2 will not come out in one pull. i would assume it would take a while of smoking for the co2 to fully get agitated out of suspension. also even if the concentration was high enough to cause issues you are not in an environment of that concentration so your next breath will give you good air.
again i am not saying filling a base only with soda is a good idea, i honestly think it is stupid for multiple reasons but i truly dont think adding a bit into a base will cause issues and also dont think the co2 even in a full base of soda would be given off fast enough or enough over a period of time to cause issues to a healthy individual
