This was a few years ago, I smoked marijuana and shortly after, I felt very dizzy, had black vision, and felt very hot. I remember I even found the immediate need to lay down on the ground since this was the coolest part of the room which was pretty embarrassing as this was at my then current boyfriend's friend's house. It was pretty scary but it ended maybe within an hour. Just curious what this may have been, never really had the chance to ask. This was definitely one of the more scariest moments in my life. Please and thank you for answering my question!!
