Acute Emergency Department Presentations Related to Cannabis

As more states legalize cannabis, more complications are becoming apparent. The emergency department (ED) tends to be the destination for most of the acute presentations. The purpose of this chapter is to introduce some of the major complications related to cannabis ingestion/exposures being seen currently. The acute issues being covered in this chapter include acute marijuana toxicity, acute mental illness (acute psychosis, depression, anxiety, and suicide/suicidal ideation), cannabinoid hyperemesis syndrome, pulmonary and cardiovascular complications, and, finally, issues related to conscious sedation.
