I can remember foil packs of chips on the Weber kettle.
Yeah white smoke.
White smoke won't kill your meal if there is "just a LIL bit of it". Got by with that sometimes. Not something you want for more than a couple of minutes?
If you can avoid the white smoke, do it.
Talking about white smoke from wood here.
A little white smoke from meat drippings never hurt my feelings?
Good luck and good smoking.
