Scientists Discover Another Beneift Of Marijuana, One That Benefits Anglers With Night Fishing

VIA The Guardian -
Now, another study provides hard evidence for the claim, revealing a cellular mechanism by which cannabis might improve night vision. The findings, published recently in the open access journal eLife, could eventually be applied to the treatment patients with degenerative eye diseases such as retinitis pigmentosa.
West had suggested that cannabis might improve vision by acting on the eye muscles to dilate the pupils, so that more light falls on the retina, but other experiments ruled this out by showing that marijuana constricts the pupils. It’s also possible that the drug can influence activity in the visual cortex at the back of the brain, but the CB1 receptor protein, which binds the psychoactive ingredient of cannabis, is found at far higher levels in the eye than in the visual cortex, suggesting that any effects the drug has on vision are likely due to its actions on retinal cells.
