• The name of the new danger of marijuana

  • French scientists have found that Smoking marijuana can lead to impaired vision. Cannabis use alters the function of the ganglion cells contained in the retina and form the optic nerve. Thus slowing down the transmission of visual signals to the brain.

    French scientists have found that Smoking marijuana can lead to impaired vision. Cannabis use alters the function of the ganglion cells contained in the retina and form the optic nerve. Their findings the researchers presented in a paper published in the journal JAMA Ophthalmology. This publication reports EurekAlert!.

    In their work, the experts used the method electroretinography, which can be used to record the biopotentials arising at light irritation. The best marker of the activity of ganglion cells in retinography is a negative wave, which is referred to as N95.

    The study took 52 participants, 28 of whom regularly smoked marijuana. Found that the latter significantly increases the time to reach the maximum amplitude of the N95 compared to the control group (9.8 milliseconds). Thus slowing down the transmission of visual signals to the brain, which may explain the disturbance of vision in those who use cannabis.

    According to scientists, their findings can be important from the point of view of public health, as they will reveal the mechanism of toxic effects of marijuana on the Central nervous system.
