an ounce the quickest? shiiiiiiiiiit. i have been known to causually smoke a half a day. and thats after work and classes. i smoke joints like some people smoke ciggaretts. lol now for my humble side. if its good bag weed its an easy task to smoke an ounce in ohhhh say 3 hours. putting it in blunt after blunt. but if its top shelf mason jar shit thats a differnt story...and probably alot of fun. lol but the biggest thing is who wants to take an O to the head and wake up the next day goin damn i wish i hadn't done that. lol
