Abstract
Urinary retention is described as an inability to voluntarily empty the bladder, with potential etiologies including mechanical obstruction and neurologic dysfunction. Abused substances like methamphetamine and cannabis can induce this dysfunction. We report a case about a patient with no prior psychiatric history with concomitant methamphetamine and cannabis use, presenting with an acute delirious state and urinary retention. Due to the multifactorial nature and acuity of a patient's presentation, clinicians should be aware of the potential for substance abuse to impact bladder function and consider this in patients who present with urinary symptoms, including urinary retention.
