So, my first post here. How do you fellas do? Been lurking a bit and the guys on another forum (not really pipe related, for the most part) didn't seem to have any experience with this. Took up the pipe about a year ago due to some jerks making it sound great at another forum and I recently had an odd experience. I had purchased a tin of C&D Bayou Nights, I opened it, smoked a bowl and enjoyed it. I then packed the tobacco into a jar for storage. That was about 3-4 weeks ago. Two days ago, I opened the jar and as soon as I unscrewed the lid (Two piece bell jar lid), it exploded off like it was under a good deal of pressure. It flew roughly ten feet across the room. (It also scared the bejeesus out of me, lol) I am unsure what the heck is going on here. My other jars tend to be more vacuum sealed, where I have to pop the lid off with my fingers. The tobacco doesn't smell 'off' to me, but I do not have enough experience with the blend to know if it smells 'on' really, if you catch my drift. Anyone else have this happen? I'm somewhat worried about smoking this stuff again, health-wise, anyone have any thoughts on what's going on? Something go bad? something go RIGHT??? I've read about swollen tins a couple times and people seem to consider that good? Same thing? Any help appreciated!
