oh yeah, another wonderful ethnobotanical to try is Inebriating Mint(Lagochilus inebrians). 5 g'z or more of that brewed into tea & schmoked in a bowl or so will give you a nice, pleasant clear-headed inebriation. It's reportedly on the endangered species list, so if you ever enjoy growing plants i'd recommend collecting the seeds from the dried flowers. be careful, they're small, bout half the size of an average cannabis seed. here's some websites for reference:

there's also a site or so that sells pure Lagochilan, the alkaloid that gives the effects, but it'll be a bit pricey.
