Butane-free smoking device

A smoking device, comprising:

• a main body defining an upper portion opening upward, the upper portion having inner walls that define a smoking chamber and an inner ledge that forms a central opening at the bottom of the smoking chamber, the main body having at least one internal flow channel formed therein which opens to the smoking chamber and extends downward through a lower portion of the main body to a lower passageway;
• a burn plate sized and shaped to be supported by the inner ledge and thus completely cover the central opening at the bottom of the smoking chamber;
• a manifold member sized and shaped to fit within the smoking chamber of the main body, the manifold member being configured to be fastened within the smoking chamber and clamp the burn plate against the inner ledge, the manifold member having a central receptacle and ports through sidewalls to provide fluid communication between the central receptacle and the at least one internal flow channel in the main body;
• and
• a lid adapted to be secured to and cover the upper portion of the main body, enclosing the smoking chamber from above, the lid having at least one air inlet,
• wherein smoking material may be placed within the central receptacle of the manifold member and onto the burn plate and the lid secured to the upper portion of the main body, and wherein the smoking material may be combusted by application of a flame to the underside of the burn plate and aspiration by a user from the lower passageway to create a flow in through the air inlet of the lid through the ports in the manifold member, through the at least one internal flow channel in the main body and through the lower passageway.
