One of the side effects of cannabis use is the potential occurrence of the famous red eyes. This blush is seen as the most obvious evidence of cannabis use. This effect is simply due to tetrahydrocannabinol (THC), which reduces blood pressure, dilates blood vessels and increases blood circulation throughout the human body.
Even if the red eyes are visible almost instantly after smoking cannabis, the effects do not last long. What are the potential long-term effects of cannabis on the eyes?
Cannabis for glaucoma
Glaucoma is an eye disease that affects the optic nerve. Therefore,many patients use cannabidiol for therapeutic purposes to treat their glaucoma, the most famous being Whoopi Goldberg.
On the other hand, an American medical journal, Jama Ophthalmology, conducted a study and explained that regular use of cannabis could delay information transmitted by the retina and ultimately damage vision. Also,the author of the study, Dr. Vincent Laprevote explains: “Such an anomaly could be imperceptible among cannabis users. However, it is important because it could reflect the changes in communication between the neural cells involved in the regular use of cannabis. »
Subconjunctival hemorrhages are blood flows in the white part of the eye and the sclera. Laser surgery, sneezing or coughing are natural causes. They generally last longer than simple “red eyes”, but can also be caused by regular cannabis use.
The bleeding can cause dilation of the pupils and take longer than expected to heal. However, it tends to disappear after 2 to 3 weeks. Feel free to talk to your doctor if this happens to you to limit the damage.
