#35 Clinical Context
Background information relevant to the evolving cannabis medicine landscape.
Clinicians need guidance on managing cannabis use in hospitalized patients because withdrawal symptoms, drug interactions, and psychiatric complications can complicate medical and surgical care. Understanding inpatient cannabis management protocols helps providers optimize pain control, reduce agitation, and prevent adverse events during acute illness when patients cannot use cannabis. This knowledge enables clinicians to have informed conversations with patients about their cannabis use history and develop safer treatment plans that account for cannabis’s effects on medications and mental health.
This article addresses the clinical management of cannabis use in hospitalized medical patients, an increasingly common scenario as cannabis legalization expands and use rates rise among diverse patient populations. Understanding cannabis pharmacology and acute effects is essential for inpatient physicians, as cannabis use can complicate anesthesia management, interact with other medications, and exacerbate psychiatric or medical conditions during acute illness. The inpatient setting presents unique challenges including withdrawal symptoms, drug interactions, and the need to assess whether cannabis use contributed to the presenting condition or may interfere with treatment. Clinicians managing hospitalized patients should systematically screen for cannabis use, document frequency and route of administration, and anticipate potential complications including cannabinoid hyperemesis syndrome, drug interactions with sedatives or opioids, and psychiatric decompensation. A practical approach for hospitalized patients includes symptom-directed management of withdrawal, adjustment of pain and anxiety protocols to account for tolerance, and clear communication with the patient about cessation during hospitalization and discharge planning.
“When a patient presents to the hospital with an acute medical or psychiatric condition, we need to know their cannabis use history with the same rigor we assess alcohol or opioids, because withdrawal and drug interactions are real clinical problems we’re not yet systematizing in most inpatient settings.”
? As cannabis legalization expands across jurisdictions, hospitalized patients increasingly present with active use or withdrawal concerns, yet clinical guidelines for inpatient management remain inconsistent and evidence-based protocols are limited. Healthcare providers should recognize that cannabis-related presentations span a spectrum from acute psychosis and cannabinoid hyperemesis syndrome to withdrawal-related anxiety and insomnia, each requiring distinct assessment and management strategies tailored to the patient’s underlying psychiatric and medical comorbidities. The complexity is heightened by variable THC potency in modern products, individual differences in metabolism and prior use patterns, and the frequent co-occurrence of cannabis with other substances or untreated mental illness, making attribution of symptoms challenging. Rather than viewing cannabis use categorically as either benign or uniformly harmful, clinicians should screen hospitalized patients for cannabis use during intake, document frequency and product type when possible, and monitor for both intoxication effects and withdrawal symptoms during the
