On a further note, most of the time this is caused by using molasses or bud sweeteners. It does not harm the plant and can actually give a much smoother flavor but the drawback is the curing times as increased exponentially. I cure my buds in glass jars after drying for a minimum of 6 months and some go a year or more before they are at their peak. It does however make a great bud become a pure smoking delight.

Just don't go overboard or you will have to literally peel the buds out of the jar and burping the jars becomes a problem from the buds sticking together.
