No, it will not dry out no matter how long the tobacco is left in the pouch as long as the relative humidity of the air is not 0%. The moisture content of the tobacco will decrease down to an equilibrium state with the surrounding air as time goes by. For example, wood's equilibrium moisture content(EMC) is 5.4% for the surrounding air's relative humidity 25%. I live in Japan and my room's average humidity in early Oct must be around 50%. I have no idea about the EMC of tobacco, but EMC of woold for 50% relative humidity is 9.5%. But, I felt the tobacco was more wet than 9.5%. I thought the tabacco has been soaked with some water absorbing agent such as glycerin.
