Figure 1. Human exposures to synthetic marijuana (THC homologs) reported to poison centers. Data from American Association of Poison Control Centers.

• 26 year old African American female with two similar presentations to the emergency room in a one month span. • She reports almost daily use of “Serenity,” which she identified as synthetic marijuana. • She presented as confused, agitated, paranoid, and disorganized in her thoughts • She also reported vague sexually based delusions. • She had a self-reported history of Bipolar Disorder and Schizophrenia, neither of which could be verified through previous records or based on retrospective collateral history.

WHAT IS SYNTHETIC MARIJUANA ? • Over 100 identified street and commercial names for synthetic marijuana products AM-1220 AM-1221 AM-2201 AM-694 Cannabicyclohexanol CP-47,497 CP-55,940

Table 1: Some of the chemical components of synthetic cannabinoids identified and present in commercially available products.

CHEMICALS IDENTIFIED AS SCHEDULE I DIAGNOSTIC WORK-UP • • • •

CBC, CMP, and TSH were within normal limits Urine Drug Screen was positive for cannabinoids CT Brain with contrast was normal a quantitative synthetic cannabinoids analysis for metabolites of JWH-018, JWH-073, JWH-122, JWH-250, and RCS-4 was sent out and found to be negative.

CLINICAL COURSE • She was admitted to the inpatient psychiatric unit, requiring seclusion, and was initially started on risperidone 0.5 mg orally twice daily, which was titrated up to 1 mg orally twice daily on her first admission. • Her acute psychosis resolved within less than 72 hours on both admissions. SYNTHETIC MARIJUANA LAB TESTING • Urine sample collected and analyzed via liquid chromatography/tandem mass spectrometry • Turnaround time ranges from 4 to 15 days • Variation among panels for components analyzed • Most include at least JWH-018, JWH-250, CP 47, 497, HU-210, and Delta-9-THC CURRENT TREATMENT RECOMMENDATIONS • Symptom-based • No current literature comparing efficacy of anti-psychotics for managing psychosis secondary to “synthetic marijuana”

CLINICAL IMPLICATIONS • Challenge to distinguish synthetic marijuana from other designer drugs • Paucity of clinically relevant testing • Concern for recent surge in the context of legalization of marijuana • Consideration of effectiveness of high-potency anti-psychotic (eg. Risperidone) in the management of acute psychosis secondary to synthetic marijuana
