that happened to me before i was justing blasting a reefer in me and i felt all of a sudden hot and colapsed, i still have no idea why that happened, it may have been the drugs in my system from the night before but not sure.
It normally takes about 8th to get me as fucked as i want to be but i just went really strange off that joint, i wouldnt worry about it i havent had anything like that since
