What is the current evidence regarding cannabinoids in symptom management and what cautions should clinicians observe?

Cannabinoids in palliative care have potential, but the evidence is not strong or uniform. There are data suggesting they may help with two symptoms: pain and nausea, but the findings are modest and inconsistent across studies. The quality of the evidence varies, with differences in study design, patient populations, product types (synthetic cannabinoids like dronabinol or nabilone, plant-derived cannabis preparations, and varying ratios of THC to CBD), dosing, and routes of administration. Because of this variability, there isn’t a universal, definitive benefit for all symptoms or all patients. Cautious use is essential. Legal and regulatory status varies by location, so clinicians must ensure compliance with local laws and institutional policies and obtain appropriate patient consent and documentation. Cognitive and central nervous system effects are common concerns, including dizziness, sedation, altered mood or perception, and potential delirium, especially in older adults or those with preexisting cognitive impairment. Interactions with other medicines are also important, as cannabinoids can affect drug metabolism (notably through cytochrome P450 pathways) and may interact with anticoagulants, antidepressants, and other agents. There is also a consideration of potential for dependence or misuse, though this risk is generally lower with prescribed, monitored use than with illicit cannabis use. In practice, use cannabinoids with caution, start low and go slow, review the evidence and guidelines for the specific symptom you’re targeting, assess individual risk factors (psychiatric history, cognitive status, polypharmacy), and ensure legal compliance. If chosen, monitor closely for efficacy and adverse effects, and reassess regularly to determine continuation, adjustment, or discontinuation.
