i had a guy stick an orange peel in my bag, it was an ounce and withn a week it got moldy, not saying i didn't smoke it bc it was moldy, but damn, maybe he left some fruit still on the peel or somethin, id on't know, what i do know is that im never sticking a damn orange peel in my bag or anyone elses bag. I do hear that a piece of bread works the same though, never tried
