if she has never smoked before, brownies might not be the best idea, as she may get too high and become uncomfortable. And with only about a gram, even if you put 3/4 of that gram into your brownie, it might not give you what you are looking for. Waterfall is a good suggestion especially if she doesn't know how to smoke really yet, as all she will have to do is inhale rather than trying to figure out how to hit a bowl or j, etc.
