Is it normal that i went blind for like a minute?
Today I donated plasma and everything was fine. I drank a lot of water yesterday and today and everything went well. Three hours after I donated, I smoked a blunt. I then went to my school and had to wait in line. As I was waiting in line, out of no where I became hot and really sweaty. I never really sweat so that was weird already. Then when it was my turn to be assisted, I went completely blind for a good minute or two. I felt like I was going to pass out any second. I got really scared and just stood there until my eyesight started to slowly resurface. I made my way to sit down to try and relax and calm down. I was out of breath and sweaty and still vision-impaired. After a couple minutes I was fine. Why did this happen? Was it because I donated plasma or smoking weed? I'm a pretty regular pot smoker so my tolerance is pretty high. Should I go see a doctor or is it something to not be worried about?
