flavoured weed?

What would happen if someone was too add amounts of pure peppermint extract or vanilla extract to the water that you are using to water your plants?

You might throw the Ph off. If you want to flavor your weed I know of a post floating around that shows you how to do it while curing your bud.

What post is that?

I'm looking for it but I know the person talked about using a grape flavored cig. paper.
