Abstract
A compact pipe for smoking cannabis features an elongated smoke pathway prior to entering the mouthpiece so as to cause smoke cooling and purification by removal of smoking debris along the pathway. An elongated serpentine groove is formed on the exterior of an elastic stem insert configured for insertion into a rigid outer shell during the pipe assembly. Elastic stem insert also serves to brush off smoke stains and deposits of smoke debris from the inside of the outer shell, making cleaning of the pipe easy and convenient. A smoke chamber is formed below the cannabis container to cause even distribution of air and smoke flow throughout the volume of cannabis to eliminate the need to frequently light up the pipe during use.
