probably depends where ur staying. in a touristy area?
when i went to greece (Kos,greek island) for 2 weeks i managed to get some from a local who was at the hotel (in the middle of no where) for whatever reason.
we also got quad bikes one day and me and my m8 smelt weed somewhere, we tried to find the plant after walkin through a few fields but couldnt spot any. my point is, its there, its just getting it somehow.
