In late February I consumed some alcohol and smoked marijuana. The next few days I felt fatigue, brain fog and headache. Eventually I started developing visual anomalies that could be described as symptoms of visual snow. These symptoms include the conventional static, palinopsia and halos along with movement of patterns which all developed over following months. Thus, I underwent an MRI about one week after experiencing initial symptoms which revealed a lesion near the right periventricular area of the brain. I was subsequently diagnosed with toxic leukoenphalopathy and discharged. Therefore, I'm wondering if visual disturbances could be symptoms of toxic leukoenphalopathy. I've also posted pictures of the mri scans
