Snap inhale (also called Ghost inhale) is a smoking technique where one takes a drag of a cigarette or other smoking substance and then opens his or her mouth, letting a cloud of smoke out, and then quickly or slowly inhales, sucking all the smoke in. This is can done by lifting the tongue up then opening the mouth and snaping the tongue down while inhaling or simply by leaving the mouth open for a short period of time thereby allowing the smoke to escape, and then inhaling.
