It depends what type, 'domestic' (ie 'standard' weed) - to me - has hints of coconut. Hashish (black, moroccan, leb) has a garlicky scent. Skunk though is more pungent and smells a lot like hops - not surprisingly perhaps as they're in the same family of plants. As Erin says, it is hard to describe. It's a nice smell afaic.
