This large-scale survey provides the first nationally representative data on how Americans actually use CBD in relation to their prescribed medications. Understanding real-world substitution and adjunct patterns is crucial for clinicians to assess potential drug interactions, therapeutic gaps, and patient safety concerns.
This cross-sectional survey of 2,880 US adults found that among CBD users, many report using it either as a substitute for or in combination with conventional medications across various health conditions. The study used a probability-based sampling method to ensure national representativeness, covering households with and without internet access. While the survey provides valuable population-level insights into CBD use patterns, it relies on self-reported data without clinical verification of diagnoses, medication regimens, or therapeutic outcomes. The findings highlight the widespread integration of CBD into existing treatment approaches among consumers.
“This confirms what I see clinically – patients are already making these decisions about CBD with or without physician guidance. The data underscores our responsibility to have informed conversations about potential interactions and safety rather than remaining silent on cannabis therapeutics.”

FAQ
How prevalent is CBD use among US adults?
This nationally representative survey found that a significant portion of US adults have used CBD, with 1,008 ever-users identified from 1,523 qualified respondents. The study provides robust population-level data given its probability-based sampling methodology covering approximately 97% of US adults.
Are patients using CBD to replace their prescription medications?
Yes, the study found that some patients are using CBD as a substitute (replacement) for approved medications rather than as an adjunct therapy. This practice raises significant safety concerns as patients may discontinue evidence-based treatments without medical supervision.
What are the medication reconciliation implications when patients use CBD?
Clinicians need to systematically inquire about CBD use during medication reconciliation, as patients may not volunteer this information. The study highlights that CBD users often combine it with or substitute it for conventional medications, creating potential drug interactions and therapeutic gaps.
What health conditions are patients commonly treating with CBD?
The study identified specific health conditions for which patients self-medicate with CBD, though the complete results aren’t detailed in this summary. Patients reported using CBD for various conditions where they felt conventional treatments were inadequate or caused undesirable side effects.
What are the clinical safety considerations when patients use CBD with other medications?
CBD can interact with conventional medications through cytochrome P450 enzyme inhibition, potentially altering drug levels and efficacy. Clinicians should assess for drug interactions and monitor patients who combine CBD with prescription medications, particularly those with narrow therapeutic windows.
