Cannabis ruderalis, or C. sativa sativa var. spontanea, is a low-THC variety or subspecies of Cannabis which is native to Central and Eastern Europe and Russia. Many scholars accept Cannabis ruderalis as its own species due to its unique traits and phenotypes which distinguish it from Cannabis indica and Cannabis sativa; however, it is widely debated by many other scholars as to whether or not ruderalis is a subspecies of Cannabis sativa.
