Cannabis Could Enhance Your Night Vision
Study finds it boosts activity in cells that transmit light information from the eyes to brain.

While previous studies have suggested cannabinoids reduce neurotransmission, researchers now found that activating this type of signalling in tadpoles instead made the retinal ganglion cells more sensitive.
