hemp

Here's the gist of the story:

Alex White Plume of the Pine Ridge Reservation in South Dakota had been trying to grow various crops on his land, but none of what he planted could sustain. Finally, after a bit of research, he decided to grow industrial hemp, a close relative of marijuana but with a much lower amount of THC. While it is not illegal to sell hemp products, it is illegal to grow it, but Plume assumed he could grow and sell the hemp due to tribal sovereignty.
