The only thing marijuana users might see in their immediate future is a bag of chips because they've got the munchies.
However, the smoke might not be the only thing clouding their vision.
Turns out, regular marijuana use may affect how quickly a person processes things in front of them, according to a new study published in the journal JAMA Ophthalmology.
Researchers claim regular cannabis use can cause problems with the retina; affecting certain cells so it takes longer for visual information to go from the eye to the brain.
Researchers looked at 52 people; 28 were regular marijuana users while 24 didn't use the drug at all.
Then came the vision tests.
The control group processed things faster at 88.4 milliseconds.
Marijuana users registered 98.6 milliseconds.
What's clear, those who used the drug had a slight delay in what they were seeing.
Experts not involved in the study say this is worrisome because it could affect other things like driving, work and other activities.
However, critics were quick to point out the flaws in the study noting not enough people were included, and it wasn't clear how much cannabis each person consumed.
The study's authors say it's preliminary, more tests are needed.
