I for one would never use it. However, this is an unending debate on the adverse effects of zinc oxide vapors from heated pipes.
Wood stoves and pipes would not get hot enough to cause zinc to become a health issue. IMHO.
There is even some stoves made of Galvanized steel.

I could be wrong but i beleive that in a chimney fire it could. Honestly i really dont have any idea if it is a real problem or not but i will not take the chance in my house or that of my customers.
i've worked in galvanizing 24yrs seen people keel over from fumes why risk it to save 30$,stoves that are galvanized it"s not in contact with heat

MELTING POINT BASE METAL (steel) : 2750 degrees F
METALLIC COATING: Zinc melts at about 800 ̊F, and vaporizes at about 1650 ̊F.
So, yeah I guess during a chimney fire one might be exposed to zinc oxide.
Most people (I hope) would be outside during a chimney fire.
Again, I would not use it.
I do however take a zinc vitamin daily to help ward off the common cold.

Many times they dont even know about it we see evidence of lots of fires and the homeowner had no ideaMost people (I hope) would be outside during a chimney fire.
when i put the blocks of zinc in kettle you can see the it off gassing as it goes in .i don"t get colds only benefit i can see 
The thing i dont know is how toxic it is i doubt that there would be enough coming off that small amount of pipe to really cause a problem but not worth the risk to me at all
The other issue with cheap galvanized warm air pipe is that it is thin metal. Stove pipe should be 24ga or heavier.

True, there really is no benefit to using it. (maybe rust resistance) But is rust even an issue? Most likely not.
No rust resistance needed indoors and the zinc coating is baked with the first few hot fire. It's a loser situation all ways.

What about blocking plate usage? I picked up a couple of thin metal sheets at Lowes, I don't think they're galvanized...
