ur all talkin bout weed like its alcohol. sugars an starches ferment into alcohol. weed doesnt get better with age after its been chopped. the THC stops being produced. it doesnt get stronger jus sitting in a bag. if anything it loses potency. the only way i know to make weed last longer is to make good, real, oldfashioned hash. an i dun even know if that lasts much longer than weed but im sure it has less of a chance to get moldy.
