Abstract
We report the case of a 35-year-old African American woman with a past medical history of HIV on HAART and history of two admissions for Cannabis induced psychosis.The patient was brought to the Emergency Department by EMS activated by her husband for a psychiatric evaluation after sudden uncontrollable agitation on seeing her husband.She reported she found the normally pleasant perfume of her husband became pungent.The pungent smell was associated with unpleasant past memories.She only recalled preceding event was Cannabis use prior to his arrival home.The triggered memories were associated with a funeral parlor of her 2-year-old sister.The patient stated that she was just 8 years old at that time and had witnessed the death of her sister.She endorsed smoking "a few blunts" one day before the flashbacks started.She described and confirmed an occurrence of similar episodes in the past after marijuana use.She admitted to use Cannabis regularly.On admission her CBC, CMP were in normal limits, ECG was normal and her quick toxicology screen did not reveal any substance.The patient's symptoms responded very well to a trial of Risperidone 1 mg per oral twice a day.She was discharged with aftercare follow-up and admitted to the long term rehabilitation program.
