Back when I was in the approximate equivalent of junior high school, one of the classic experiments done in chemistry was making ammonium chloride, which is used as flavouring in sweets [1] here.
It was tasted.
As the teachers were responsible and I'm sure they didn't want to take safety risks, I'm inclined to believe it was safe to do. (I can't remember how it was made but I suppose the only risks would be from unclean glassware or contamination by some other substance.)
