you caught me in the right mood for experimenting. just vaped a trench of a herbal tea blend for the sake of science. it contained curled mint, sweet bramble leafs, peppermint, rooibos, ginger, nettle, lemongrass, cinnamon, elderflower and ginseng. the taste was actually sweet and pleasing to the taste buds. i remember trying out my girlfriend's herbal cigarettes as she was about to quit smoking a couple of years ago. they smelled and tasted like shit, so i'm quite pleased vaping herbs other than mj is not such a bad experience after all. now loading a trench of the real stuff, i'm still amazed about the boxes efficiency in terms of the size of the load.
