I never really used to buy my own stuff, I just used to get a big bag in with friends and have a huge session. Before Christmas I bought some stuff to take home and I only smoked it very occassionally. I finished it recently, but after smoking two joints with a friend we weren't especially high or stoned. I thought it might have been that I hadn't especially looked after the weed very well and that I had kept it for a couple of months. It was definitely drier than when I bought it. I have ruled out quantity (I packed those spliffs). and tolerance (I really don't smoke that often, and my friend even less) The weed was great when I first got it! High for hours Is keeping weed for a long time a bad idea then?
