pretty sure dagga is just aussie slang for weed, as for that other stuff im pretty sure they sell it in high times, doesn't really do much, nothing matches weed, lol not even close. ive had experts at smoke shops sell me all kinds of shit, primrose seeds, broom, hops, salvia, all saying it is "reminicent of marijuanna" well hops tastes nice and is weeds closest cousin but wont get you high at all, broom is an irish weed that looks and tastes like ground corn cob, doesn't work either, never tried the primrose, but salvia is a 5 min halusinatory that is really cool but not like weed either.
