Have you tried a nose dab yet? It's just a regular dab you take through the nose instead of the mouth. It gets to the brain slightly faster, is less harsh on the lungs, but quite intense on the sinuses. Highly recommended for sinus problems from colds and bloackages to pilocytic astrocytomas (brain/sinus tumors). Strangely it still makes you cough even if you don't involve the lungs, but so good it'll bring tears to your eyes!
