i completely fogged out a 80's model 4-door station wagon with one hit off a blunt as big around as a quarter... i had to put it out after that hit cuz everytime i went to take a hit again, even the smallest one it started up this 5-min coughing fit...probably doesn't really sound like that much, but damn if you could of only seen it, off one hit i had some serious ass munchies it looked like you poured chlorine in my eyes and i coughed for 10 mins straight right after the hit.
