BACKGROUND
Spice is a synthetic cannabinoid that is readily available for purchase in smoke shops at relatively low cost. Spice is not detectable upon routine drug screening, making it an increasingly popular new street drug.
METHODS
A 21-year-old man presented with new-onset seizures. During the next 2 days, he developed uncontrollable hypertension, agitation, respiratory failure requiring intubation, pulmonary hypertension, and acute kidney injury (AKI) with a maximum blood urea nitrogen/creatinine level of 54/7.90 mg/dL. A complete renal workup was negative, but his urine sediment revealed granular casts. A discussion with family and friends revealed that this patient had smoked Spice during the last month. His renal function started to improve with supportive therapy, and his AKI resolved by the time of discharge without renal replacement therapy.
CONCLUSIONS
Spice differs from marijuana because it is a cannabinoid receptor type 1 and 2 agonist. The pathologic mechanism of AKI remains unclear, but the condition likely is attributable to acute tubular necrosis or acute interstitial nephritis, as proven by biopsies performed in previous case series. It is important to raise awareness that a new Spice strain that may be circulating in the Southern California Inland Empire can endanger young users who may develop seizures, respiratory failure, and AKI.
