Can You Use Cannabis to Restore Your Natural Sleep Cycle?

Insomnia isn’t that uncommon

Sleep is essential for maintaining our mental and physical health, yet it eludes many adults.

According to the National Sleep Foundation, 50 to 70 million U.S. adults experience symptoms of a sleep disorder. About 30 to 40 percent of the population will experience insomnia at some point in their lives, and about 10 to 15 percent of adults will deal with chronic insomnia.

So if getting shut-eye is becoming harder and harder, you’re not alone.

With so many people experiencing sleeping disorders, there’s been a rise of interest in one controversial cure: cannabis. Many in the medical marijuana community refer to cannabis as an effective treatment, with little to no side effects, for a range of sleeping disorders.

“Marijuana is an effective sleep aid because it restores a person’s natural sleep cycle, which so often falls out of sync with our schedules in today’s modern lifestyle,” says Dr. Matt Roman, a medical marijuana physician.

Whether you have a sleep disorder or you’re having difficulty sleeping after a stressful day, cannabis might be a choice for you. Marijuana’s analgesic properties might provide some relief for those with chronic pain, while the anti-anxiety properties can soothe a stressed out mind and body.

There are different strains of marijuana. Some are more energizing, and some are calming and sedating depending on the balance of the different cannabinoids.

First, here’s a quick primer on the science behind marijuana. This herb works because it contains different cannabinoids, two of which you’ll see most often:

  • Cannabidiol (CBD). CBD has a number of health benefits, and is nonpsychoactive, meaning it doesn’t cause you to feel “high.”
  • Tetrahydrocannabinol (THC). THC, a psychoactive cannabinoid, is primarily responsible for that “high” feeling.

Something else THC is responsible for? Inducing sleep . So you’ll want a strain that contains more THC than CBD.

According to a 2008 study , ingesting marijuana strains with higher levels of THC typically reduces the amount of REM sleep you get. Reducing REM sleep means reducing dreams — and for those who experience PTSD, it could mean reducing nightmares.

So the theory is that if you spend less time dreaming, you’ll spend more time in a “deep sleep” state. The deep sleep state is thought to be the most restorative, restful part of the sleep cycle.

Still, REM is important for healthy cognitive and immune functioning, and marijuana with higher THC levels could impair your sleep quality if taken long term.

But this isn’t true across the board. Some studies have found that sleep can actually be impaired by regular use of marijuana. It’s clear that marijuana changes sleep cycles.

Smoking of any kind is a known health risk and should be approached with caution. Also, medicinal use of marijuana is still illegal in many areas.

Talk to your doctor about your sleep cycles. There may be long-term health consequences with interrupted REM, because much of the immune function repair takes place in deep sleep.

Please use marijuana responsibly. As with all forms of smoking, your risk of COPD can increase. Smoking marijuana is hazardous to the lungs, especially for those with asthma or other respiratory conditions. The use of marijuana while pregnant or breastfeeding isn’t recommended.

Long-term marijuana use has been shown to have changes on the amount of gray matter in the brain. For teenagers, marijuana seems to have even more profound long-term and lasting effects on the brain and isn’t recommended.

Marijuana use isn’t recommended for anyone under 25 years of age because of the long-term effects on learning and recall.

More research on marijuana for medicinal purposes as well as the risk of COPD is still needed.

Is cannabis an answer to entering the land of sleep? From strains to timing, here’s what you need to know about cannabis as a nightcap.

Does Marijuana Help You Sleep?

A recent study concludes that marijuana use might actually disrupt your sleep. However, experts point out there may be other factors involved.

Marijuana may make you sleepy, but does it really help you sleep?

With the increasing frequency of marijuana legalization and its medical use throughout the United States, many are turning to the drug to treat insomnia and sleep disorders.

However, a study from the University of Michigan concluded that depending on how frequently an individual uses marijuana, it may not help them sleep at all.

It may actually worsen their sleep quality.

The study recruited 98 subjects who were divided into three groups: daily marijuana users, non-daily marijuana users, and a non-user control group.

Individuals were disqualified from the study for a variety of reasons that could affect sleep.

Illicit drug users and binge drinkers couldn’t participate, nor could individuals working night shift jobs, or those using sleeping medications.

Researchers found that that the daily-use group had higher levels of insomnia (almost 40 percent) compared to non-daily users (10 percent) and the control group (20 percent).

“These results are consistent with previous studies showing an association between sleep disturbance and heavy marijuana use in adults,” the researchers wrote.

The significance of their report is that it suggests that while marijuana may help some individuals in the short term or through intermittent use, continual use makes insomnia worse.

“The effects of marijuana on sleep in intermittent users may be similar, in part, to those of alcohol where improvements in sleep… have been reported with intermittent use, whereas daily use results in the worsening of sleep,” they wrote.

Another facet that Deirdre Conroy, PhD, a clinical associate professor in the University of Michigan Department of Psychiatry and lead author on the study, touches on in a separate publication is what happens when daily users stop using marijuana.

Their sleep worsens during a withdrawal period if they attempt to quit using the drug or use it less frequently.

The study was limited in that quantity of use wasn’t measured.

All daily users were considered to be “heavy” marijuana users, but researchers admit they were, “unable to know if the sleep reports of daily users were a result of frequency of use or quantity of use.”

They say that future studies should recruit individuals who only smoke minimally to observe how quantity could potentially affect sleep quality.

Medical marijuana is also used to treat a variety of ailments from anxiety to PTSD.

Those ailments almost certainly play a role in sleep disorders.

Researchers discovered that when they controlled the study for anxiety and depression, the difference in reported insomnia levels disappeared.

“This raises questions about how marijuana is affecting people with and without anxiety and depression,” Conroy, who is board certified in sleep disorder medicine, told Healthline.

“We don’t know if our participants started using [marijuana] to treat anxiety and developed insomnia or if they used [marijuana] to treat insomnia and developed anxiety,” she explained. “Additional studies looking more specifically at these relationships will help us better understand this relationship.”

The study further complicates the medical literature on the relationship between marijuana and sleep — which is already inconsistent.

“To date, controlled clinical data with regard to the impact of cannabinoids on sleep is limited and somewhat mixed,” Paul Armentano, the deputy director of the National Organization for Reform of Marijuana Laws (NORML), told Healthline.

He points out a 2017 review on the subject matter as evidence of that.

“Cannabis is frequently used by patients as a sleep aid and they typically report subjective benefits from cannabis with regard to getting to sleep and staying asleep,” Armentano said.

One of the problems in making a conclusive assessment is that marijuana contains numerous different chemicals that affect the body’s endocannabinoid system.

The two most prominent, tetrahydrocannabinol (THC) and cannabidiol (CBD), both exist in varying amounts, depending on the strain of marijuana.

Therefore, there’s the potential for different strains to affect sleep differently.

The review that Armentano brought up suggests that CBD may be helpful for insomnia, but THC may impair sleep quality in the long run.

Marijuana is also known to decrease REM sleep — the stage closely related with dreaming.

A separate study concluded that the “sleepy” effects of THC seem to lessen as a user’s tolerance grows.

Another study, a newer one from 2017 , found that marijuana users who decreased usage over time had improvements in anxiety, depression, and sleep quality.

In short, considering the many variables involved — including mental health issues, marijuana strain and potency, and quantity of use — a definitive answer on the relationship between marijuana and sleep remains somewhat elusive.

However, Conroy’s research may be helpful in sorting out some of the details of who are better candidates for using medical marijuana for sleep disorders.

“If you have depression, cannabis may help you sleep. But if you don’t, cannabis may hurt,” she writes.

The research also points to future work investigating a potential optimal dosing strategy.

That is, if smoking heavily every day is too much, how would less frequent, smaller doses affect sleep quality?
