Dark datura is a venom that causes periodic double vision and blurring while the player is under its effects. This type of venom is favored by the White Legs, likely due to its powerful properties and due to the availability of its ingredients in Zion.
This item can be crafted by the player character.

Behind the scenes
The dark datura bears a strong resemblance to the real world Datura wrightii, colloquially known as "sacred datura root," which upon consumption results in unpleasant hallucinations and sensory distortions.
Sometimes, even after applying the antivenom, the blurred vision effect may persist. [verified]
