Marijuana, also known as cannabis, has become increasingly accessible, with more cannabis shops in Canada than major fast-food chains. This widespread availability raises questions about its impact on sleep. While some users claim it helps them sleep, others argue it disrupts their rest. Let’s explore how cannabis affects your body and brain, and whether it could be impacting your sleep, energy, and mental capacity over time.
One of the main components of cannabis, THC, is known to reduce sleep onset latency, meaning it can help you fall asleep faster. This is particularly beneficial for individuals who struggle with insomnia or racing thoughts at bedtime. Research indicates that marijuana can help people with insomnia not only fall asleep more quickly but also enjoy longer sleep durations, which can enhance daily functioning and overall well-being. Similar benefits have been observed in individuals with depression and PTSD, who often face sleep challenges.
Even for those without specific sleep issues, a single dose of cannabis has been shown to reduce the time it takes to fall asleep, increase total sleep time, and decrease sleep disruptions. However, it’s important to note that repeated use may lead to complications, which we will discuss later.
CBD, the non-psychoactive component of cannabis, also shows promise. It may aid in thermal regulation by lowering body temperature, a key factor for sleep. Additionally, CBD might interact with adenosine, a chemical that accumulates in the brain throughout the day, promoting tiredness. Some studies suggest that CBD can increase sensitivity to adenosine, encouraging sleepiness. Moreover, CBD appears to reduce anxiety by calming the amygdala, potentially leading to more restful sleep. However, the effects of CBD are dose-dependent, and both very low and very high doses may promote wakefulness. The optimal dosage for sleep is still under investigation.
While THC may help you fall asleep faster, it can significantly impair the overall quality of your sleep. A normal sleep cycle includes light sleep, deep sleep, and REM sleep, all essential for brain health and cognitive function. THC appears to negatively impact REM sleep, delaying its onset and reducing its duration. Many users report fewer dreams when consuming cannabis, supported by eye-tracking studies showing decreased REM activity. Chronic REM sleep deprivation can lead to anxiety, mood disturbances, and, in severe cases, hallucinations.
If you’ve attempted to quit cannabis, you might have experienced a rebound phase with more vivid and frequent dreams. This occurs as your body compensates for the lack of REM sleep after prolonged use. Some people believe cannabis aids their sleep, but upon cessation, they may experience worse sleep than before, leading to a difficult decision: continue using it for some sleep quality or quit and risk insomnia.
Regular users often develop a tolerance to THC, requiring higher doses to achieve the same effects, making it challenging to break the cycle. Sleep disturbances are common among regular cannabis users, with studies indicating that those who consume marijuana are significantly more likely to experience insomnia compared to non-users. For instance, a study involving 14,000 students found that insomnia was 45% more prevalent among cannabis users. Daily users were twice as likely to suffer from insomnia, and chronic users were more likely to sleep less than six hours or more than nine hours a night, both associated with health risks.
Whether these sleep issues are directly caused by cannabis or merely correlated remains unclear. Some studies suggest that individuals with sleep problems may be more inclined to use cannabis as a remedy.
In summary, the effects of cannabis, particularly THC, on sleep are not entirely favorable. While a single dose may provide temporary relief, repeated use can deteriorate sleep quality, especially affecting REM cycles. CBD shows potential benefits but requires further research, particularly regarding its long-term effects.
Personally, I took a month off from using cannabis and noticed that I felt more rested than I had in a while. It wasn’t a drastic change, but it was a positive one. I plan to use cannabis more selectively now that I understand its potential negative impacts on sleep. Taking breaks from regular indulgences can be beneficial for both mental and physical health.

Keep a detailed sleep diary for two weeks, documenting your sleep patterns, cannabis use, and any other factors that might affect your sleep. Analyze the data to identify any correlations between cannabis consumption and changes in your sleep quality or duration. Share your findings with the class and discuss potential reasons for the observed patterns.
Participate in a structured debate with your classmates. Divide into two groups: one advocating for the positive effects of cannabis on sleep and the other highlighting the negative impacts. Use evidence from the article and additional research to support your arguments. This will help you critically evaluate the complex relationship between cannabis and sleep.
Design an infographic that visually represents the effects of THC and CBD on sleep. Include information on how these compounds influence sleep onset, duration, and quality, as well as their impact on REM sleep. Present your infographic to the class and explain the key points in a brief presentation.
Engage in a role-playing exercise where you advise a friend who is considering using cannabis to improve their sleep. Use information from the article to discuss the potential benefits and drawbacks, and suggest alternative strategies for improving sleep quality. This activity will help you apply your knowledge in a practical context.
Research alternative methods for improving sleep, such as meditation, exercise, or dietary changes. Prepare a short presentation comparing these methods to cannabis use, highlighting their effectiveness, potential side effects, and long-term impacts on sleep health. This will broaden your understanding of sleep aids beyond cannabis.

Marijuana, cannabis, or whatever you prefer to call it, is widely available these days. In Canada, there are more cannabis shops than all the major fast-food chains combined. Given my personal interest in this substance and my focus on sleep, I’ve started to wonder what effect cannabis has on sleep. Some people swear by it as a sleep aid, with nearly 50% of users reporting that they use it to help them sleep, while others claim it worsens their sleep. So, what happens in your body and brain when you consume cannabis, and could it be negatively affecting your sleep, energy levels, and mental capacity in the long run?
First, let’s look at the positive aspects. One of the main benefits of THC is that it can decrease sleep onset latency, meaning that with THC in your system, you may fall asleep faster. This is particularly helpful for those who struggle with racing thoughts before bed or suffer from insomnia. Studies have shown that marijuana can help people with insomnia not only fall asleep faster but also sleep longer, leading to improved daily functioning and overall well-being. Similar benefits have been observed in individuals with depression and PTSD, who often experience poor sleep.
For those without specific sleep issues, research indicates that a single dose of cannabis can reduce sleep onset latency, increase total sleep time, and decrease sleep disruptions. However, repeated use of cannabis can lead to problems, which we will discuss shortly.
There has also been promising research into CBD, the non-psychoactive component of cannabis. CBD may help with thermal regulation by lowering body temperature, which is necessary for sleep. Additionally, it may interact with adenosine, a chemical that builds up in the brain throughout the day, making you feel tired. Some studies suggest that CBD may increase sensitivity to adenosine, promoting tiredness. Furthermore, CBD appears to reduce anxiety by quieting the amygdala, which could lead to more restful sleep. However, the effects of CBD are dose-dependent, and both very low and very high doses may promote wakefulness. The ideal dosage for sleep is still being researched.
Now, let’s discuss the negative aspects. While THC may help you fall asleep faster, it can significantly decrease the overall quality of your sleep. A normal sleep cycle includes light sleep, deep sleep, and REM sleep, all of which are crucial for brain health and cognitive function. However, THC seems to negatively impact REM sleep, delaying its onset and reducing the overall amount. Many users notice a decrease in dreams when consuming cannabis, which is supported by eye-tracking studies showing reduced REM activity. Chronic deprivation of REM sleep can lead to anxiety, moodiness, and in extreme cases, hallucinations.
If you’ve tried to quit cannabis, you may have experienced a rebound phase where your dreams become more vivid and frequent. This occurs because your body is compensating for the lack of REM sleep after prolonged use. Some people believe cannabis helps their sleep, but when they stop, they may experience worse sleep than before, leading to a tough decision: continue using it for some sleep quality or quit and risk insomnia.
Many regular users develop a tolerance to THC, requiring higher doses to achieve the same effects, making it harder to break the cycle.

Whether these sleep issues are caused by cannabis or are simply correlated is still unclear. Some studies suggest that individuals with sleep problems may be more inclined to use cannabis as a solution.
In summary, the effects of cannabis, particularly THC, on sleep do not look promising. While a single dose may help temporarily, repeated use can worsen sleep quality, especially affecting REM cycles. CBD shows potential benefits but requires further research, particularly regarding its long-term effects.
