I smoked some stress on two different occasions that both times everything turned white. I couldn't see shit. Like fog and fading everything white. I had my eyes open and i could hear everything and everyone around me but i just couldn't see them. The first time it happened i was driving. My friend had to get the wheel and guide it to pull over. Second time i was in my homies backyard chillin. Craziest feeling ever and scary at the same time. Now i only been smokin chronic and it hasn't happened since. I still trip, just not that bad. HAPPY SMOKIN!!!!!!!!!!!
