@entity14031 ( @entity3784 ) has unique @entity137 that may be difficult to diagnose. We present a case of a young @entity1 who presented to our @entity341 ( @entity341 ) initially diagnosed with recurrent @entity410 . Paramedics brought a 19-year-old @entity1 to the @entity341 . Witnesses noted "shaking," which the @entity1 did not recall. The @entity1 denied fever, antecedent @entity130 , or neurological complaint. She was recently administered @entity2812 for @entity162 . She was a former alcoholic with no history of developing withdrawal. She admitted to marijuana use but denied use of any other illicit substances. Her vital signs and physical examination were unremarkable. She had a normal brain computed tomography, electrocardiogram, and laboratory evaluation. There was no @entity167 detected. Her urine drug screen was negative for opiates, @entity1245 , @entity2072 , @entity889 , @entity7353 , @entity12781 , and tricyclic antidepressants. She was diagnosed with new-onset @entity410 and discharged home. No abnormalities were seen in the brain magnetic resonance imaging scan and electroencephalogram. She was scheduled for a @entity299 , but never followed through. Two months later, she presented to the hospital again for a similar complaint. Coworkers reported witnessing sudden @entity3173 and @entity911 . On @entity341 presentation, the @entity1 was tachycardic with a heart rate of 110 beats/min and had @entity346 . She was alert with a flat affect. She did not recall events but answered questions appropriately. Repeat radiographic and laboratory evaluations were normal including urine drug screen and computed tomography. Upon questioning, she admitted to abusing @entity3784 for the past several months. A serum @entity3784 level at this time was 988.3 ng/mL. She was admitted to the hospital for 24 hours without sequelae. All further diagnostic testing was cancelled, and she was referred to a drug rehabilitation program. Abuse of @entity3784 is increasing in incidence. The serum level of our @entity1 was almost 10-fold greater than the reported therapeutic level. The @entity137 of @entity3784 is unique, and abuse should be considered in all @entity1 presenting to the @entity341 with new-onset @entity410 . @entity14031 abuse should be considered in young adults who present with previously undiagnosed @entity410 activity.

XXXX abuse masquerading as a recurrent seizure disorder.
