More cannabis consumers in Michigan are turning to a lesser-known cannabinoid called cannabinol (CBN) to help with sleep, as research suggests it may have mild calming effects and help reduce nighttime awakenings. However, the science behind CBN's sleep benefits is still limited compared to more well-known cannabinoids like THC and CBD.
Why it matters
As research into cannabis compounds continues, more attention is being given to lesser-known cannabinoids like CBN, which could provide an alternative to traditional sleep aids like melatonin for some consumers. However, it's important for patients to use caution, as CBN is still a biologically active compound that may interact with medications or underlying conditions.
The details
CBN, or cannabinol, is a cannabinoid that forms as THC breaks down over time, meaning older cannabis tends to contain higher levels. Unlike THC, CBN is only mildly psychoactive, and researchers think it may affect sleep regulation, pain signaling, inflammation, appetite, and other nervous system activities. Some studies suggest CBN may help reduce nighttime awakenings and improve sleep quality, especially when combined with THC or CBD, though more research is needed. Possible side effects of CBN include drowsiness, dizziness, changes in blood pressure, drug interactions, and increased sedation with other medications.
- CBN forms as THC breaks down over time, meaning older cannabis tends to contain higher levels.
- When consumed as an edible, the effects of CBN are typically strongest about two or three hours after ingestion.
The players
Dr. Evan Litinas
A Michigan-based physician and cannabis medicine expert with nearly 15 years of experience helping people use weed wisely. He co-owned one of Ann Arbor's first dispensaries and has been working with the University of Michigan to study how cannabis can help with pain and reduce opioid use. These days, he's focused on educating patients, training healthcare professionals, medical cannabis research and developing products for wellness-minded cannabis users—especially seniors.
What they’re saying
“Early evidence suggests CBN may play a role in supporting sleep, relaxation, and overall wellness but more research is needed to fully understand the benefits and risks.”
— Dr. Evan Litinas, Physician and cannabis medicine expert
What’s next
Researchers continue to study the potential benefits and risks of CBN, as well as how it interacts with other cannabinoids and terpenes in cannabis products. Patients interested in trying CBN for sleep support should consult with a healthcare provider, especially if they have any underlying conditions or are taking other medications.
The takeaway
While CBN shows promise as a natural sleep aid, it's important for consumers to use caution and start with low doses, as the science behind its effects is still limited compared to more well-known cannabinoids. Incorporating CBN into a holistic approach to sleep and wellness, rather than relying on it alone, may be the best strategy.
