Yeah, I don't like when my cocaine is moist either I buy 3.5g and after leaving the bag open overnight it might way 2.75 or 3. I paid $50 or $75 for water.
If it were me, I would have it in the bags with the top open in a warm dry place for several hours. Like a cookie sheet in the oven, in as low as it goes, for a couple of hours. Another alternative is a desiccant pack. They can be $0.02 each. Made out of a coffee filter or a saved teabag. It could have rock salt Epsom salt clay from your yard, rice.... I could name at least 10 more things just put them in the oven on low or somewhere else that is warm for a couple hours so all the moisture is driven out and add them to the bags. Don't make bags on rainy days if you can help it. Check the relative humidity try to work when it's low
