Missoula, MT: Administration of cannabis improves night vision in a dose-dependent manner, according to the findings of a case study to be published in the July issue of the Journal of Ethnopharmacology.
Researchers administered oral THC to one individual; analogous field studies were performed on three separate subjects before and after smoking cannabis. All four subjects were field-tested for night vision with a Scotopic Sensitivity Tester-1.
“In both test situations, improvements in night vision measures were noted after THC or cannabis,” authors found.
“The current study supports the previous ethnobotanical observations that cannabis may improve night vision,” they concluded. “This effect seems to be dose-dependent and cannabinoid-mediated. Further study may reveal whether this clinical application of cannabis could be added to treatment of pain, spasticity of multiple sclerosis, and nausea of chemotherapy as recognized indications for this ancient substance.”
