Welcome to GC! Never owned an iguana, but my friend Becky had one... until it got stolen. Also, do not feed an iguana cannabis! Cannabis intoxication in three Green iguanas (Iguana iguana). (UK) (abst – 2011) Cannabis intoxication in three Green iguanas (Iguana iguana) - PubMed This report describes clinical signs and plasma biochemical changes associated with significant cannabis consumption in three Green iguanas (Iguana iguana) which resulted in seizures, cardiovascular and digestive tract aberrations, elevated hepatic enzymes and bile acid concentrations for a number of weeks post recovery. One case required extensive antiseizuring therapy to recover. All Green iguanas eventually made a full recovery. Granny
