Hello. If you dry and cure the cannabis first, freezing it is a good way to store the cannabis.
I find that when I freeze the cannabis it makes the stocks that hold the THC resin crystals too the leaf, brittle.
So don't handle it too much after it comes out of the freezer and you should be fine.
It might be better to freeze the dried cannabis in mason jars so the buds don't get their THC knocked off in the plastic bags.
That's why they freeze it before making hash or kief, the THC crystals fall off easier.
