Goldcoster,
I'd be very carefull about smoking something just because it "looks or smells" like pot. The Marijana plant is and looks the same all over the world (trade mark leaves) with the differances being in the type (sativ./Indi.). My take on this is, if you don't know the chem. make up on this plant, DON'T SMOKE IT.
It could make you sick or worse,KILL YOU !!!
