The drowsiness that cannabis sometimes produces is often considered a side effect, but for a number of users, it is the only thing that enables deep, healing slumber.
Marijuana and sleep have a long history, spanning over several millennia.
Today, many users swear that marijuana helps them overcome their sleeping problems, sometimes even the toughest of insomnias.
Sleeping disorders are actually omnipresent in everyday life.
One study suggested that one in three young adults between 18 and 25 suffer from some form of sleep deprivation.
Is this something we should worry about?
The answer is a resounding yes.
Sleeping problems can lead to a number of other health issues and turning to doctors for help is crucial for maintaining overall health.
However, a common solution for insomnia and other sleeping disorders are prescription sleeping pills which can put you to sleep in minutes.
Unfortunately, sleeping pills are classified as “sedative hypnotics” and doctors usually prescribe them just for short-term use.
Sleeping pills are addictive.
Hence, many patients are looking for a more natural solution.
I’ve been having sleeping problems myself for nearly a decade.
I am a very light sleeper naturally, and every little sound wakes me up. Sometimes, I toss and turn in my bed for hours. Needless to say, this can be exhausting and frustrating.
I can’t even remember when was the last time I slept through an entire night without waking up at least once… Unless I take a few puffs before going to bed. Then I sleep like a baby.
So, why should we take addictive medication when there is an all-natural solution for a good night sleep?
Here’s what science says on marijuana and sleep
Believe it or not, the research on the effects of marijuana on sleep is still in its infancy.
Since the studies we have are very limited, the results are often confusing, with divided opinions and conclusions.
Everything we know about weed’s effect on sleep today originated from a study done in 1973. (1)
In this research, a group of patients suffering from insomnia received different doses of THC, from 10 to 30 mg.
Most patients reported that they fell asleep faster and easier, without waking up at night.
Their time to falling asleep has also reduced, on average, for an hour.
However, there was one unpleasant side effect — the weed hangover.
Whenever subjects received higher doses of THC they reported hangovers the following morning.
Both the study and the experiences of users found that taking too much cannabis before going to sleep can produce uncomfortable side effects, such as being sleepy throughout the following day.
Furthermore, taking too much cannabis could make it more difficult to fall asleep in the first place, due to marijuana’s biphasic effect — low and high doses can have completely different effects in different users.
Recent studies concerning marijuana and sleep were all conducted on smaller groups, which is probably why the conclusions are equivocal.
This study from 2013 looked into the sleeping patterns of 17 participants suffering from sleep disorders and apnea (disrupted breathing during sleep) after using dronabinol (artificially made cannabis). (2)
After three weeks of incrementally increasing the dose of dronabinol, the researchers concluded that THC (as a compound) was safe for use, as it eliminated all breathing difficulties and provided more high-quality sleep overall.
Of course, the researchers also pointed out that more clinical trials are necessary in order to confirm whether marijuana helps with insomnia.
One of the latest studies on the same issue had a similar conclusion to its predecessors. In this study, however, the test subjects were regular cannabis users, instead of people who had no any relevant history of cannabis use.
Thirteen men who used marijuana on a daily basis were given 20 mg’s of THC during the day. The results were also promising:
All subjects fell asleep quicker but felt more sleepy the next day.
Now that we know that studies give us the green light to go ahead, it’s time to find out…
How exactly does marijuana affect sleep?
When we sleep, we go through four cycles, the last of which is the REM (rapid eye movement) phase.
Here are the sleep cycles:
- Half awake stage — the first 10 minutes of falling asleep.
- Light sleep stage — heart rate slows down and body temperature drops. It’s a little bit harder to wake up from this stage.
- Slow wave sleep (usually called deep sleep) — begins 35 to 45 minutes after falling asleep. Waking up from this stage usually results in feeling groggy for a couple of minutes after.
- REM phase — this is when we dream. REM occurs about 90 minutes after deep sleep and lasts for about 10 minutes.
So, how does marijuana influence our sleeping patterns?
Basically, it all has to do with the interaction of cannabis and our endocannabinoid system (which we’ll refer to as the ECS).
Speaking in simple terms, the ECS is a network of endocannabinoid receptors and activators — a cellular, microscopic system that has an important role in our body.
This system regulates things like pain perception, anxiety response, sleep, general calmness of the mind, appetite, peripheral energy metabolism, it provides neuroprotection (in fact, cannabis is proven to relieve epilepsy in more than several different studies) and many more, all of which you can read about in this review. (3)
When the THC kicks in, as the studies showed, the time needed to fall asleep reduces, which leaves patients more time in the third, deep sleep phase.
Deep sleep is very important for our recovery, as that is when our body regenerates and produces energy for the following day.
As a result, using marijuana before going to sleep helps us spend less time in the REM stage and more time in the healing, deep sleep stage.
It’s no wonder that people who use cannabis usually don’t have dreams.
However, this may cause a “dream pile-up”, or commonly known as the “REM rebound” effect.
After they stop using cannabis, some users experience very intense dreams for the next few nights or weeks, depending on the individual.
Fortunately, this phenomenon wears off and everything goes back to normal pretty quickly.
Also, besides cannabinoids, some other substances in cannabis have a role in regulating sleeping cycles.
Terpenes are chemical compounds that give the plants their enchanting aromas and contribute to the healing properties many plants possess.
Cannabis is no exception.
There are more than 80 terpenes unique to cannabis, some of which are nature’s very own sleep remedies.
One such terpene is linalool.
Linalool gives marijuana its unique smell but is also present in the likes of lavender, mint, and coriander. Studies have shown that linalool aids in relieving insomnia, as it produces deep relaxation and sedation.
If you’re not familiar with the role of terpenes (such as linalool) in medical cannabis, I suggest you hop over to our interactive guide to 15 cannabis terpenes.
Indica or Sativa for sleep?
The easiest way to answer this question is to resort to a piece of ancient cannabis wisdom:
Sativa is like coffee. It boosts your energy and focus while sparking up your creativity.
Indica calms and sedates, but it also produces the “couch-lock” effect.
So, if you are looking for a strain to help you fall asleep faster, stick to indicas.
In general, Cannabis indica has higher levels of THC and CBD, but it also has a unique combination of terpenes, all of which play a role in its positive effects on sleep.
Their chemical composition helps indicas produce a soothing effect on the processes in our brain, including sleep.
Indica is best used at night, right before sleep, and is also commonly used for treating pain, symptom which often goes hand in hand with insomnia.
THC or CBD for sleep?
There are a number of cannabinoids in the herb, but the two most prevalent are tetrahydrocannabinol (THC) and cannabidiol (CBD).
Strains low in CBD and high in THC produce a cerebral high, while other high-CBD strains make you relaxed but clear minded.
Strains with equal parts of THC and CBD will not make you as high, which is a good thing if you’re suffering from lack of sleep.
That being said, THC and CBD affect sleeping patterns differently.
Again, in general, indicas rich in THC should most likely put you into a deep slumber pretty quickly.
However, newer studies suggest that the plants containing 1:1 ratio of THC to CBD are also very effective in treating sleep disorders.
Recreational marijuana users usually smoke to get high and euphoric, and they often stick to strains that are higher in THC.
There are specially bred strains that are made to be as THC-heavy as possible.
These strains will probably keep you awake for a while, so avoid them if you are looking for a sleep solution.
Marijuana that’s high in CBD is mostly used in treating anxiety.
Anxiety is one of the main reasons for keeping us awake at night, so perhaps a right CBD strain can also provide you with enough relaxation to help get your sleeping schedule in order.
If you’re suffering from lack of sleep, you should stick to indica strains that are rich in CBD, and aim for a 1:1 ratio of THC to CBD.
10 best strains for sleep disorders and insomnia
Depending on your overall health and the cause of your sleeping problems, it will take some time to find a strain that’ll work the best for you.
Marijuana affects us all differently, so you will have to do your own bit of research and try out different strains.
As I outlined above, you should stick to indica-dominant strains with no more than 20% THC. You don’t want to be too groggy the next morning either, right?
Keep in mind that the following strains are recommended for nighttime use because they’re almost all “downers”.
Here are some strains that’ll help you go into a deep slumber:
Northern Lights (THC 16 – 21%)
Northern Lights is one of the favorites among sleeping disorder sufferers, as it is very effective in treating insomnia. It will make your body numb and lazy, so be ready to be put away to bed almost instantly. It’s also great for stress relief and, if you are a beginner, make sure to keep the dosage low.
Pink Kush (THC 20%)
Pink Kush is very high in THC, so even the smallest of doses will put you to sleep immediately. This is a hybrid, with sweet and flowery taste, and is one of the best natural remedies for sleep when you need it the most.
Blue Cheese (THC 20%)
Great strain to end your day, Blue Cheese has a sweet berry and cheese taste. If you get the dosage right, it’ll give you a relaxed high. It’s also slightly uplifting and will boost your appetite as a bonus.
Lavender (THC 27%)
Lavender is an indica that is proven to relieve sleeping disorders. It will bring forth a body relaxation, followed by slight euphoria, which gradually puts you to sleep. With its high THC content, it is one of the most potent strains, so take it easy the first time around.
Skywalker (THC 15-23%)
This strain is best used after a long day, when you just want to chill a little bit before going to bed. After the short wave of euphoria, when it starts to wear off, Skywalker will leave your body sedated and peaceful — ready for a good night’s rest.
LA Confidential (THC 19-25%)
This indica is high in THC and puts most users to sleep after just an hour or two. LA Confidential is also good for treating pain, as well as stress and anxiety, and will undoubtedly leave your body utterly lazy.
Afghani (THC 15-20%)
What you can expect from Afghani is a heavy couch-lock followed by a deep sleep. It is considered to be a classic, mostly for its blissful high and heavy sedation. Patients often use it for treating pain and insomnia.
Granddaddy Purple (THC 17-23%)
Granddaddy Purple is an indica with very sweet and fruity taste and after a quick influx of euphoria, it will lull you to sleep. It is very popular among the medical users for its pain and stress relieving properties.
Grape Ape (THC 18-21%)
Simply put, Grape Ape is perfect before hitting the sack. It produces full-body relaxation and will carefully guide you into a deep sleep. Grape Ape has sweet and fruity flavor and a grape smell. It’s also very promising as a painkiller.
Bubba Kush (THC 14-22%)
Almost a pure indica, Bubba Kush will make you feel lazy and weightless, with very powerful body relaxation. Its couch-lock high is strong, making it perfect for those having trouble falling asleep.
If you have difficulties sleeping and would rather avoid conventional pharmaceuticals, marijuana could just be your next best bet. Take note that, before you start using it as a replacement for conventional drugs, you should consult with a qualified medical professional.
