if you puke after you own an IV injection of a cancer chemotherapy drug, do you zest the drug surrounded by your mouth?

No.
The drug may effect the taste of your saliva or other bodily fluids (not blood), but the drug will not be surrounded by the fluid because the body will filter at least some ingredients out.
sometimes you do. In my satchel I always do, try sucking on a pice of frozen candy.

Good luck

Ginger ale, ginger snaps and hard candies help some of the time.
