So I have gotten to a point where when I smoke, I'll load a bowl and take a few puffs for maybe 10, 15 minutes, then put thepipe down and go do something else. I might come back to It in a few hours, or sometimes even the next day. Smoking this way, it sometimes might take me 2 days of stop and go smoking to finish a bowl. My question for all those who DGT out there; do you ever leave an unfinished pipe for that long, and moreover, does the tobacco in the bowl suffer any ill effects from sitting in the pipe that long? I'm curious as to when it gets really humid outside if leaving the tobacco in that long would affect moisture content of the tobacco, or once it's lit is the tobacco pretty much safe against outside influence?
