Pneumomediastinum and Pneumorrhachis Associated With Cannabinoid Hyperemesis Syndrome.

More complications continue to be reported with the increasing use of marijuana (MJ) in the United States, including the increasing prevalence of Cannabinoid Hyperemesis Syndrome (CHS). To our knowledge, based on a thorough review of the literature, we present the third case of CHS with associated pneumomediastinum (PM) and the first case of pneumorrhachis (PR) in a young healthy patient. The main objective of this paper is to heighten awareness of CHS and its potential complications. A brief discussion of a focused history is essential for diagnosis, proper evaluation, and treatment.
