my junior year of high school i bought 6 very healthy js off of my buddy during spring break. i smoked 2 of em and gave one away to one of my friends. then my freshman year of college one of the guys on the football team and i decided we wanted to get baked. i told em i had some stuff but it was old so i wasn't sure if it would work. i had kept it in a ziploc bag in an xbox 360 box. so i brought up the three js to school. my buddy from college and i went on a roady and clan baked the crap outta his car. we only smoked 2 of the js and to be honest with i had never been so high in my life. we were high for 4.5 hrs then later that night we went on another roady that night and smoke the last one we had and once again i was soooooooo baked. so weed does for sure never go bad as long as you have kept it in a ziploc baggy.
