What are cannabinoids and CBD?

Let’s start from the very beginning and define what CBD is. Do you know that a cannabis plant on average contains about 113 various chemical compounds or so-called cannabinoids with such famous tetrahydrocannabinol (THC) and cannabidiol (CBD) included? There is no similar plant because the ratio and concentration of the cannabinoids depend on the strain, how and where it has grown.

Today it’s no secret that THC and CBD have different impacts on your body and mind. Being psychoactive, both cannabinoids affect the brain but in different ways. Therefore, THC gets you high meanwhile CBD remains non-impairing. It’s a reason that CBD is used as medical marijuana for the treatment of a variety of conditions like depression, insomnia, anxiety, chronic pain, and other diseases and disorders.

Therefore, each cannabinoid interacts with your endocannabinoid system — a network of cannabinoid receptors in the central nervous system and brain. Herewith, the system maintains certain body functions and state of balance/stability/homeostasis like:

  • Appetite;
  • Mood;
  • Regulating circadian rhythms that affect the quality and duration of your sleep, etc.

Consuming marijuana, active compounds of the cannabis interact with CB1 and CB2 receptors of the endocannabinoid system, providing different effects. Here with, CBD may affect sleep and wake cycles along with relieving pain, stress, anxiety, etc.

How do CBD and cannabinoids work?

New and still poorly understood marijuana effects on sleep make it vital to do more and deeper research to learn how exactly cannabinoids (with CBD included) work and how marihuana helps you sleep. What we know now is that CBD along with cannabinoids of the plant interact with proteins and cells in your brain so that it can improve the quality of sleep as well as prolong sleep. Yet, there are a lot of questions left to answer.

What does the research say about CBD and sleep?

Does marijuana affect your sleep? Several studies and researches were conducted in the last decade to answer the question. There are a number of studies that prove that you can use cannabis as a sleep aid.

Before we start to elaborate on the studies, first and foremost, it’s vital to establish the reasons for your sleep disorder. According to the data, there can be such reasons for insomnia as:

  • Medications. Some medications you take can disturb the sleep/wake cycle.
  • Physical conditions. Chronic pain, restless leg syndrome, etc. can also cause poor sleep.
  • Mental health disorders. Nightmares, bad and/or short sleep can be provoked by post-traumatic stress disorder (PTSD), anxiety, depression, and so on.
  • Environmental factors. In case you have an uncomfortable bed, continuous loud noises (living near the airport, trail station, factory, etc.) that stress you out can cause sleep disorders as well.

CBD can be helpful when insomnia is caused by the mentioned external factors. Below you’ll find the information about the recent studies and their results to make things clear.

According to the investigation, CBD can reduce the level of cortisol. It’s a hormone of stress that helps us to wake up in the morning and also it can be a reason for insomnia. As the results of the research demonstrate:

  • 160 mg of CBD oil can prolong sleep duration;
  • 40, 80, and 160 mg of CBD plus 5 mg of the placebo (nitrazepam) helped the participants to fall asleep.

Another study showed that CBD oil can act as a sedative, decreasing cortisol level, when its dosage was 300-600 mg.

There was another research conducted in 2019 with 72 participants involved (25 experiencing poor sleep and 47 — anxiety) to explore the effects of CBD oil combined with the other medications prescribed. Here are the results of the 3-months study:

Follow-up Improved sleep (%) Worsened sleep (%)
First month 66.7
Second month 56.1 26.8
Third month the results are very close to the previous follow-up results

Using the doses of CBD in the range from 25 mg to 175 mg, the researchers found that the most effective dosage of CBD oil for sleeping exceeds 25 mg and was close to the maximum. Though cannabis can be helpful for sleep disorders in the short term, you should be ready that the effects can be not sustained. What’s more, the effectiveness of CBD depends on your current medication.

Thanks to the results of the investigations conducted in 2014, 2017, and 2018, we also know that CBD oil can:

  • Affect the sleep cycle and improve the symptoms of RBD (REM sleep behavior disorder);
  • Be helpful in treating grogginess, excessive daytime sleepiness, etc.;
  • Reduce chronic pain and cortisol that also can help you sleep and/or prolong the sleep duration.

How to use CBD for sleep?

Currently, there is a wide variety of CBD products in different formats to use for medical purposes and not only. Depending on the location and CBD type, cannabis for sleep can be legal or not. Let’s check 3 main CBD types to keep in mind:

  1. Full-spectrum: all the cannabinoids, flavonoids, and terpenes are saved in the extract. Thus, you will get both THC and CBD compounds.
  2. Broad-spectrum: In this case, the extract contains all the beneficial compounds within the plant along with CBD but THC — it is removed here. This type is the best choice for those who take regular drug tests or a THC-free approach is required/preferred.
  3. CBD isolate: all the compounds of the plant are removed, leaving only CBD.

The way of consumption, as well as dosage of marijuana as a sleep aid, depends a lot on the CBD type used. Below you’ll find some general principles of using CBD oil for insomnia and cannabis for sleep disorders.
