Background:

Cannabis (marijuana) has known therapeutic uses, including antiemetic properties.
Synthetic cannabinoids are established antiemetics for chemotherapy-induced nausea.
Limited recognition exists for chronic cannabis use causing cyclic vomiting syndrome.

Purpose of the Study:

To highlight the association between chronic cannabis use and cyclic vomiting syndrome.
To discuss cannabinoid hyperemesis syndrome (CHS).
To report the first known case of CHS in a psychiatric patient.

Main Methods:

Literature review on cannabis use and gastrointestinal effects.
Clinical case identification and description.
Analysis of symptoms including compulsive bathing.

Main Results:

Cannabinoid hyperemesis syndrome (CHS) is a recognized condition linked to chronic cannabis use.
CHS presents with cyclic nausea, vomiting, and often compulsive bathing.
This case represents the first reported instance of CHS in a psychiatric patient.

Conclusions:

Cannabinoid hyperemesis syndrome is an important differential diagnosis for cyclic vomiting.
Healthcare providers should consider CHS in patients with unexplained cyclic vomiting, especially those with a history of chronic cannabis use.
The presentation of CHS in psychiatric patients warrants further investigation.
