Catnip and marijuana are different enough that I wouldn't expect them to cost the same. However, I don't see why it wouldn't be similar to growing bittering hops like the ones used by beer homebrewers. I can buy a pound of "Mosaic" hops -- 450 grams -- for $30 at my local homebrew supply store. That's less than 7 cents per gram....
