If you’ve been comparing hemp products for a better night’s rest, you’ve probably run into two similar-sounding cannabinoids: CBD and CBN. They come from the same plant, but people tend to reach for them for different reasons. Here’s the short version: CBD is the all-day “calm and unwind” cannabinoid, while CBN is the one most people associate with winding down at night. Many people actually use them together. Below, we’ll break down the real difference, what current research suggests, and how to choose.
What is CBD?
CBD (cannabidiol) is the most abundant and most studied cannabinoid in hemp. It’s non-intoxicating, meaning it won’t produce a “high.” People commonly use it throughout the day as a wellness routine to support a general sense of calm and relaxation. Because it’s so widely available, it’s usually the first cannabinoid people try.
What is CBN?
CBN (cannabinol) is a minor cannabinoid that forms as hemp ages. It’s often nicknamed “the sleepy cannabinoid,” and it’s typically used in the evening rather than during the day. Because CBN is present in much smaller amounts naturally, it’s usually concentrated into dedicated nighttime products like tinctures and gummies.
The key difference for sleep: falling asleep vs. staying asleep
This is where the two really separate:
- CBD is more associated with easing everyday stress and tension that can keep your mind busy at bedtime.
- CBN is the one people specifically seek out for the staying asleep part of the night.
If your challenge is a racing mind at the end of the day, people often start with CBD. If your challenge is waking up repeatedly during the night, CBN is usually the more targeted choice.
What does the research actually say?
It’s important to be honest here: research on CBN is still early and far less extensive than research on CBD. That said, one randomized, placebo-controlled trial found that a 20 mg nightly dose of CBN was associated with fewer nighttime awakenings and less overall sleep disturbance, without increasing next-day grogginess. Interestingly, in that study adding CBD did not further boost CBN’s effect. CBD, meanwhile, has been studied more broadly for stress and relaxation than for sleep directly.
The takeaway: the early signals for CBN and nighttime rest are encouraging, but this is not settled science, and individual results vary widely.
Which one should you choose?
- You lie awake with a busy mind: start with CBD, or a CBD-forward product.
- You fall asleep fine but wake up during the night: CBN is the more targeted option.
- You want both: a combined CBN + CBD formula is popular because it pairs daytime-style calm with nighttime support.
Not sure where to start? Our CBN + CBD Sleep Gummies combine both cannabinoids in one nighttime gummy, and our CBN Sleep Tincture is a good pick if you prefer a fast, adjustable dropper format.
How to use CBN and CBD for sleep
- Start low. Begin with the lowest suggested serving and give it time before increasing.
- Mind the timing. Gummies and tinctures take time to kick in — many people take them 30 to 60 minutes before bed.
- Be consistent. Cannabinoids often work best as part of a nightly routine rather than a one-off.
- Pair with good sleep habits. Dimming screens, a cool room, and a consistent bedtime all help.
Frequently asked questions
Can you take CBN and CBD together?
Yes — many nighttime products intentionally combine them, and they’re commonly used together.
How much CBN should I take for sleep?
Many people start around 10–20 mg in the evening and adjust from there. Always follow the serving guidance on your specific product and start on the low end.
Will CBN make me groggy in the morning?
In the trial mentioned above, participants did not report increased next-day fatigue, but everyone responds differently. Start with a small serving to see how you feel.
Is CBN legal?
Hemp-derived cannabinoids containing less than 0.3% delta-9 THC are federally legal under the 2018 Farm Bill. State rules can vary.
Will CBN or CBD show up on a drug test?
Standard drug tests look for THC, not CBD or CBN. However, full-spectrum products contain trace THC, so if testing is a concern, choose a broad-spectrum or THC-free option and check the product’s lab report.
