A system for efficiently generating and inhaling vapor of herbs and incense including a hollow container having a stable base and an open mouth in an upper surface of the container, the container having an aperture in the surface, the aperture displaced from a lip of the open mouth, the container partially filled with water. Also provided is a circular diffusion element positioned upon a surface of water within the container, a region within the container above the diffusion element defining a vapor collection chamber. Further provided is a diagonally-oriented tube having an upper and a lower end, the tube secured within the aperture, the upper end defining an herb-burning bowl within which are placed herbs to be burned, the lower end having a filter, the lower end immersed in the water, the filter permitting vapor to escape into the water but limiting escape into the water of larger herbal debris of the herb-burning bowl. Also included is an inhalation cylinder having an upper end and a lower end, the lower end selectably attachable within a periphery of the open mouth of the container and in fluid communication with the mouth. A vacuum pump is located proximally and externally of the cylinder, having a vacuum input from the cylinder and a positive pressure output into the cylinder above a level of the vacuum input, the vacuum pump providing a pressure gradient from bottom to top of the inhalation cylinder and from the water surface diffusion means to the mouth of the container.
