Educational Pearls:

Around 30 patients with cannabinoid hyperemesis syndrome (CHS) randomized treatment in three arms with 8mg Zofran, Haldol 0.05 mg/kg, and Haldol 0.1 mg/kg
Haldol arms performed better on all measures compared to Zofran
Extrapyramidal symptoms were significantly higher in the Haldol group than Zofran, especially the high-dose Haldol group
