Radula marginata (Wairuakohu) is a species of plant in genus Radula, a genus of liverworts. It is native to New Zealand and Tasmania.[1][2] It has been found to contain cannabinoids.[3]

Cannabinoids

Users smoking the plant have experienced barely-discernible to absent effects.[4] The cannabinoid is not THC, the main psychoactive chemical in cannabis, but it is of similar molecular structure.[3] The liverwort contains perrottetinene and perrottetinenic acid.[3] The quantity of cannabinoid present is much less than in cannabis.

The liverwort grows as a common weed. Owning, growing and distributing the liverwort is legal.

Radula marginata has a long history of traditional use as a rongoā (Māori herbal medicine),[5] and is a taonga of the Māori people of New Zealand, so any attempt to prohibit its use would be a breach of the Treaty of Waitangi .
