I got some buds at the end of March, and have smoked with a friend about 5 times since then. The 4th time we got amazing highs. But during that time, the pipe was dropped and chipped near the mouthpiece. It was still usable at that time; later she glued the broken piece back on. The actual bowl area was not affected in the fall. Then, this past week we smoked a 5th time with the current buds I have, but we were not able to get very high, if at all. I felt some effects but we were both quite disappointed. The weed I have happens to be kind of dry and flaky. I have tried to preserve it, I keep it in a ziploc bag in a pirouette cookie tin with a top. I just recently put it in the fridge to see if that makes it better. Has my weed possibly lost its potency because it is too dry? If so, can I make it moister? I have heard of tricks involving orange peels, apples, and breathing in the jar or bag and closing it to trap the moisture. I have also heard that DO any of these work? Also is it possible that the chipped/cracked mouthpiece on the pipe might have affected how much smoke we were getting.
