Just hang and dry them! First off, the mites won't make you sick to smoke them. Secondly, from what I read, as the plant dries, they will head upward toward what (they think) is the juicier top of the plant. In reality, they are heading toward the coat hanger or whatever you are hanging the plant from. When your plants get dry, the mites should be gone, looking for something to munch on on the hanger (wash or toss the hanger).
