I know this thread is a bit old, but the information still seems useful/relevant.

Smoking while sick with chest congestion really doesn't seem like a good idea, but I'm not sure if vaping while sick is bad.

Granny, you seem very knowledgeable about all of this stuff! Do you use a water attachment with your vaporbros? Is that healthier or just more difficult to keep clean? Would you vape when you have flu or bronchitis or wait until you are better to vape? Have you ever had any breathing issues with the vaporbros?

hashhazardly makes a good point about sterilizing and keeping equipment clean... but I'm not sure how one could sterilize vaporizer whips.
