Pot Smoking: Friend Or Foe Of Rem Sleep?

Marijuana, or cannabis, is a popular sleep aid, with around 70% of young adult casual users reporting that they use it to help them sleep. However, the effects of marijuana on sleep are not yet fully understood. While some studies suggest that marijuana can help people fall asleep faster and improve sleep quality, others indicate that it may negatively impact sleep, particularly REM sleep.

REM sleep is important for healthy cognitive and immune functioning. Marijuana use has been linked to reduced REM sleep, which could have implications for memory and mood regulation. However, for people with PTSD, reducing REM sleep may help to alleviate nightmares.

Overall, the available evidence suggests that while marijuana may provide short-term benefits for sleep, long-term use could have negative consequences for sleep quality and brain function. More research is needed to fully understand the effects of marijuana on sleep and its potential as a sleep aid.

Marijuana use can decrease the duration of REM sleep

REM sleep is important for healthy cognitive and immune functioning. Reducing REM sleep means reducing dreams, which can be beneficial for people with PTSD by reducing nightmares. However, long-term use of cannabis with higher THC levels could impair sleep quality.

Some studies have found that daily cannabis users are more likely to experience sleep problems than occasional users or non-users. Additionally, long-term cannabis use may have consequences for sleep, including less time spent in deep sleep and a longer time to fall asleep.

Healthcare professionals generally discourage the long-term use of any sleep aid, including cannabis, as it may have unwanted effects on the brain, such as difficulty with learning, memory, and focus. It is also hazardous to the lungs, especially for people with respiratory conditions.

THC is the main psychoactive cannabinoid in cannabis and has sedative effects

THC, or tetrahydrocannabinol, is the main psychoactive cannabinoid in cannabis. It is responsible for the high associated with cannabis use and has a range of therapeutic benefits, including pain relief.

THC has sedative effects, and research indicates that it may improve breathing during sleep, making it a potential therapy for obstructive sleep apnea. It plays an active role in altering sleep architecture, particularly by reducing REM sleep and increasing deep, slow-wave sleep and lighter stages of non-REM sleep. While THC typically acts as a sedative, it can have stimulating effects for some people, especially those new to cannabis or taking higher doses. In these cases, using cannabis before bed may result in a longer time falling asleep.

The sedative properties of THC help shorten sleep latency, enabling people to fall asleep more quickly. THC interacts with cannabinoid receptors in the brain, increasing levels of the sleep-promoting chemical adenosine and suppressing the brain's arousal system. This combination of effects contributes to the sedative nature of THC.

However, it's important to note that a too-heavy concentration of THC can lead to next-day grogginess. Additionally, long-term, heavy cannabis use may have consequences for sleep, including reduced time spent in deep sleep and longer times to fall asleep.

CBD has no psychoactive effects and may reduce anxiety and pain

CBD, or cannabidiol, is the second most prevalent active ingredient in cannabis. While it is an essential component of medical marijuana, it does not cause a high by itself and is not psychoactive. According to a World Health Organization report, CBD "exhibits no effects indicative of any abuse or dependence potential".

CBD has been touted for a wide range of health benefits, and there is strong scientific evidence for its effectiveness in treating some of the most challenging childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome.

There is also growing evidence that CBD may help with anxiety. Studies and clinical trials are exploring the common report that CBD can reduce anxiety. A 2020 review of existing studies concluded that CBD has potential for treating anxiety disorders such as post-traumatic stress disorder, generalized anxiety disorder, and social anxiety disorder. A 2019 study found that 300mg of CBD significantly reduced anxiety symptoms in 57 adult males.

CBD may also help with insomnia, in part by helping address chronic pain and anxiety. A 2023 systematic review suggested that CBD, either alone or paired with tetrahydrocannabinol (THC), may improve insomnia and sleep.

In addition, CBD may help with chronic pain. Human studies are substantiating the claims that CBD helps control pain. One animal study suggests that CBD could help lower pain and inflammation due to arthritis when applied to the skin. Other research indicates that CBD may inhibit inflammatory and neuropathic pain, which are difficult to treat.

CBD is readily obtainable in most parts of the United States, though its legal status has been in flux. All 50 states have laws legalizing CBD with varying degrees of restriction. The 2018 Farm Bill removed hemp-derived products, including CBD, from the Controlled Substances Act, making it virtually impossible to keep CBD illegal at a federal level. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws.

When it comes to safety, CBD is generally reported to be well-tolerated, but side effects are possible, such as changes in appetite and weight, fatigue, and diarrhea. It is important to consult a healthcare professional before taking CBD, especially if you are taking any medications or supplements.

Long-term cannabis use may have consequences for sleep, including less time spent in deep sleep

Cannabis, also known as marijuana, is a popular sleep aid, with around 70% of young adult casual users reporting that they use it to help them sleep. However, studies suggest that long-term, heavy cannabis use may have negative consequences for sleep, including less time spent in deep sleep.

Deep sleep, also known as slow-wave sleep, is the most restorative and restful part of the sleep cycle. During this stage, the body engages in powerfully restorative functions, such as repairing cells and strengthening the immune system.

Research has shown that long-term, heavy cannabis use is associated with less time spent in deep sleep. A 2008 study found that heavy marijuana users showed lower total sleep times and less slow-wave sleep than a drug-free control group. Another study from 2021 revealed that adults who used weed 20 or more days during the last month were 64% more likely to sleep less than six hours a night.

It is important to note that the effects of cannabis on sleep may depend on various factors, such as the method of consumption, the strain of cannabis, and the individual's response. While long-term cannabis use may decrease deep sleep, occasional or short-term use may have different effects.

Additionally, the impact of cannabis on sleep is a complex and evolving area of research. Further studies are needed to fully understand the relationship between cannabis and sleep, including the potential benefits and risks associated with its use as a sleep aid.
