A water pipe of the type for smoking grown plant substances, and particularly the rare plant substances such as herbs and the like which are relatively expensive. The water pipe includes a first elongate tube having a central water chamber formed therein with a secondary tube extending into the water chamber and terminating beneath the normal level of water contained within the water chamber. At the upper end of the secondary tube is a bowl for containing the grown substance which is capable of being ignited for purposes of smoking. Disposed within the first tube above the water level thereof is a unique adapter which may be fixed within the first tube or otherwise removably disposed therein and which prevents the spillage of water from the upper end of the first tube in the event that the device is inadvertently tipped over. This adapter effectively works as a water entrapment device which permits the passage of smoke, but also prevents the spillage of water when the device is inadvertently tipped over.
