I remember blacking out once, i was completely embarrassed. My girlfriend, my brothers and their friends were all laughing at me. We smoked a blunt, probably full of stems and seed(black guy rolled it up). hahaha I got up, started feeling the tunnel vision, by the time i opened and closed a glass sliding door i couldn't see at all. I fell to the ground, got right back up and regained consciousness within a minute or so. It had to be the shwags fault.
