It works fine in a camp fire and therefore it will work fine for
grilling. Where fine means don't consider using it in a neighborhood
grill off for bragging rights but any use less intense than that will be
okay. This is burger cooking wood not slow cook BBQ smoking wood.

Poplar grows very fast so even though it's a "hardwood" it burns fast.
Expect to go through plenty.
