CBD and Drowsiness

When it comes to catching some Zs, sometimes we could all use a little help. For some, that means taking an over-the-counter sleep aid like Benadryl or Tylenol PM. Others might opt for a more natural remedy, like chamomile tea or lavender oil. And still others might turn to cannabidiol, better known as CBD. CBD is a compound found in the cannabis plant, and it’s been gaining popularity in recent years as a natural treatment for a variety of conditions. But how does it affect sleep? Let’s take a look.

How CBD – Sleep

CBD works by interacting with the body’s endocannabinoid system, which is responsible for regulating a number of important functions, including sleep, appetite, and pain response. Research suggests that by modulating the endocannabinoid system, CBD may help to improve sleep quality (best quality CBD flower). In one small study, participants who took 25 milligrams (mg) of CBD per day reported better sleep and less anxiety. 

However, it’s important to keep in mind that this study was done on a small sample size (just 40 participants), so additional research is needed to confirm these results. Additionally, the effects of CBD may vary from person to person. Some people report feeling more alert after taking CBD, while others say it makes them drowsy. 

CBD and Sleep

There is some evidence to suggest that CBD may help with insomnia. A 2018 study looked at the effects of CBD in people with chronic pain. The study found that those who took CBD slept better than those who didn’t. 

CBD may also help people who have trouble falling asleep. One study gave participants a 25-milligram (mg) dose of CBD before bedtime. The participants fell asleep more quickly than those who didn’t take CBD. They also slept more soundly and for longer periods of time. 

The Bottom Line

If you’re struggling to get a good night’s rest, you might be considering trying CBD. While research on the subject is still in its early stages, there is some evidence to suggest that CBD may help improve sleep quality. However, it’s also important to keep in mind that the effects of CBD can vary from person to person so what works for one person might not work for another. If you do decide to give it a try, start with a low dose (25 mg or less) and increase gradually as needed. And be sure to consult your doctor before trying any new supplement especially if you’re taking medication for another condition.

How CBD Makes You Drowsy

CBD affects the brain in a number of ways. One of those ways is by binding to serotonin receptors. Serotonin is a neurotransmitter that helps regulate mood and social behavior, among other things. When CBD binds to serotonin receptors, it can help increase levels of serotonin in the brain, which can in turn lead to feelings of relaxation and calmness. This effect is thought to be one of the main reasons why CBD makes you drowsy. 

How Long Does the Effect Last

CBD’s effects vary from person to person, but they generally last for a few hours. That said, if you take a high dose of CBD, the effect may last longer. The drowsy effect of CBD is also more likely if you take it with alcohol or other medications that can cause drowsiness. If you’re taking CBD for the first time, start with a low dose and see how you feel before increasing it.


Cannabidiol, or CBD, is a compound found in cannabis plants that has been shown to have a number of powerful effects on the body, including drowsiness. How long does this effect last? It depends on the person, but generally for a few hours after taking CBD. If you’re thinking about taking CBD for the first time, start with a low dose and see how it affects you before increasing it.
