It is normal for your eyes to blackout after smoking weed?
a few months ago i was at a friends and had been up all night on speed and was constantly smoking weed, i stood up and walked across the room and then i went a bit dizzy and my eye seem to blackout from the corners in, it was blurry at first then went from grey fading into black til both eye are completely black, i shouted my mate because i couldnt see and she came over and held up fingers infront of me i couldnt see them at first then my eye started fading into wat looked like a sketch everything was grey and the outlines of thing such as a chair arm, the corner of a some drawers, my friends bob haircut and her 3fingers she was holding up, was all i could see after blinking for a while i could see fine, my friend told me that my pupils went really big when i couldnt see,this has happened a few more times to me since that night, and now today me and my mate had a joint and about an hour later the same thing happened to her, and yet again her pupils went really big, we do not have a clue why this happened. please help :)
