Cannabis and Polypharmacy Leading to Hospitalization for Acute Confusion and Inability to Ambulate

Inability to ambulate is a common issue for which an Emergency Department (ED) may request inpatient admission to the hospital. Frequent contributing factors include advanced age, spinal stenosis, osteoarthritis, deconditioning, and polypharmacy. We present an interesting case of a patient admitted due to inability to ambulate who had a significant acute decline in function coincident with the introduction of gabapentin in the setting of heavy tetrahydrocannabinol (THC) use.
