Millions of Americans use marijuana to fall asleep, but the evidence of its effectiveness is mixed. Cannabis may help restore your natural sleep cycle, and its analgesic properties may provide relief for people with chronic pain. However, THC, the cannabinoid that induces feelings of euphoria, increases heart rate, which can cause disturbances in sleep patterns. Studies have found a correlation between higher cannabis use and higher rates of anxiety, which can also impact sleep. Furthermore, while cannabis may help with sleep in the short term, long-term use may lead to insomnia and impaired sleep quality. Quitting cannabis can be challenging due to withdrawal symptoms, including insomnia, and it may take months for sleep disturbances to resolve.

What You'll Learn
Short-term vs. long-term effects of THC on sleep
Cannabis is often used as a sleep aid due to its relaxing and sedating properties. It is believed to help with falling asleep faster and improving overall sleep quality. However, the effects of THC on sleep can vary between short-term and long-term use, and it's important to understand the potential benefits and risks.
Short-term effects of THC on sleep
In the short term, THC can help people fall asleep faster and improve sleep quality, especially during the first half of the night. It increases the time spent in the non-rapid eye movement (NREM) sleep stage, which is associated with feeling refreshed upon waking up. Additionally, THC reduces rapid-eye movement (REM) sleep, leading to fewer dreams and nightmares, which can be beneficial for individuals with PTSD.
Long-term effects of THC on sleep
Long-term use of THC for sleep may lead to the development of a high tolerance. While it can still help with falling asleep, it may also cause more frequent awakenings and fragmented sleep during the second half of the night. This can result in a negative impact on sleep quality, with a potential relapse of insomnia or even worsening of sleep issues. Additionally, long-term cannabis use may have adverse effects on brain function, including difficulties with learning, memory, and focus.
The method of THC consumption also plays a role in its effects on sleep. Inhaling cannabis through smoking or vaping can have faster effects, but these may also fade faster. On the other hand, THC-infused drinks, edibles, and other swallowed or sublingual options are considered safer and may have fewer side effects.
While cannabis may provide short-term relief for sleep issues, it is generally not recommended as a long-term solution due to its potential negative impact on sleep quality and other possible side effects. It is always advisable to consult with a healthcare professional to discuss individual concerns and explore the potential benefits and risks of using THC for sleep.

THC's impact on REM sleep
THC, the main psychoactive component of cannabis, has been shown to suppress REM sleep and decrease sleep latency. However, this is not always the case. THC appears to play the most active role in altering sleep architecture and the time spent in specific sleep stages.
THC has clear sedative effects, helping users fall asleep more quickly and perhaps lengthening the early phases of lighter sleep. However, a too-heavy concentration of THC can lead to next-day grogginess. THC-rich strains of cannabis are likely to reduce levels of REM sleep, the stage of sleep when we do our most active dreaming, and when the brain does a lot of memory processing and consolidation of acquired information, as well as the processing of emotional experiences.
While THC can reduce REM sleep, it can also increase deep, slow-wave sleep, which is considered the most restorative and restful part of the sleep cycle. This may be why THC is often associated with improved sleep quality. However, REM sleep is important for healthy cognitive and immune functioning, and cannabis with higher THC levels could impair sleep quality if taken long-term.
There is also a link between THC and sleep disorders. THC is increasingly recognized as a promising therapeutic tool for sleep disorders associated with abnormal REM sleep and disruptive dreaming, including REM Sleep Behavior Disorder and PTSD. However, long-term cannabis use may have unwanted effects on the brain, including difficulty with learning, memory, and focus.

THC's effect on the brain
THC, or tetrahydrocannabinol, is the primary psychoactive ingredient in cannabis, producing a mental "high". It acts as a partial agonist with high affinities for both CB1 and CB2 receptors, which are found in high densities in the cerebral cortex, hippocampus, caudate/putamen, and other regions of the brain. The effects of THC on the brain include:
Sedation: THC has been found to promote sleep, with many users reporting that they use marijuana to help them fall asleep. This is likely due to the increase in adenosine, a sleep promoter, that occurs when THC binds to CB1 receptors in the brain.
Reduced REM sleep: Strains of cannabis with higher levels of THC have been found to reduce REM sleep. While this may be beneficial for those with PTSD by reducing nightmares, REM sleep is important for healthy cognitive and immune functioning, and long-term use of high-THC strains could impair sleep quality.
Cognitive impairments: Research has found that heavy lifetime cannabis users exhibit reduced brain activity during working memory tasks, with similar effects seen in recent users. This decline in brain activity was associated with worse performance on tasks requiring memory and information processing. Neuroimaging studies have also revealed changes in white matter in early-onset cannabis users, which could impact communication between different regions of the brain.
Potential negative effects on the developing brain: Individuals who start heavy recreational marijuana use before the age of 16, when the brain is still developing, may perform more poorly on cognitive or behavioral tasks involving the frontal cortex, such as memory, attention, and judgment. Long-term cannabis use has also been associated with difficulty in learning, memory, and focus, although more research is needed to understand the mechanisms behind these changes and whether they are reversible.
While THC can have beneficial effects for sleep and other conditions, it is important to consider the potential risks and side effects, especially with long-term use or for individuals under the age of 25.

THC and sleep disorders
Sleep disturbances are among the top three conditions for which people report using medical cannabis. However, the evidence supporting the use of cannabis products to improve insomnia symptoms and other sleep disturbances is limited.
THC, or tetrahydrocannabinol, is one of the most studied cannabinoids. It is the primary active constituent of marijuana and has a sedative effect. Some studies have shown that THC and THC derivatives, used either alone or in combination with CBD, improve self-reported sleep scores. 71% of patients reported a subjective improvement in their sleep, with 39% reducing and/or discontinuing prescription therapy. However, it's important to note that the research on the impact of cannabis on sleep is still in its infancy, and the availability of marijuana has outpaced the science.
In the short term, marijuana can help people fall asleep and improve sleep quality in the first part of the night. However, in the second part of the night, users may experience more awakenings and fragmented sleep. THC may also reduce the amount of REM sleep, which is important for healthy cognitive and immune functioning. Reducing REM sleep can impair sleep quality if taken long-term and may have negative effects on mood regulation and memory. Additionally, THC may increase blood pressure and cause "brain fog."
Marijuana is like many other sleep aids in that it may help in the short term but can make things worse in the long term. Using marijuana routinely to get to sleep may have a negative impact, and insomnia can return with more frequent use and abrupt discontinuation. It is also important to note that marijuana products are stronger than they once were, and smoking or vaping cannabis is hazardous to the lungs. THC-infused drinks, edibles, and other swallowed or sublingual options are considered safer methods of use with fewer side effects.

Quitting THC and sleep
Quitting THC can be challenging, especially if you've been using it to help you sleep. It's important to understand the potential challenges and have a plan to address them.
Firstly, it's essential to recognize that the relationship between THC and sleep is complex. While THC can induce sedation and help some individuals fall asleep faster, its long-term use may negatively impact sleep quality. This is because THC can impair REM sleep, which is essential for healthy cognitive and immune functioning. As a result, discontinuing THC use can lead to withdrawal symptoms, including insomnia and sleep disturbances, which may take months to resolve.
If you're struggling with insomnia after quitting THC, there are several strategies you can try. Firstly, it's crucial to consult your doctor, as they can provide personalized advice and support. Additionally, you can explore alternative sleep aids such as melatonin, a natural chemical produced by the brain that encourages sleep. Practicing good sleep hygiene is also essential, including maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and engaging in relaxation techniques like deep breathing or yoga.
It's worth noting that the effects of THC on sleep can vary depending on the individual and their specific conditions. For example, THC may be more effective in helping individuals with sleep issues due to chronic pain, restless legs, PTSD, or MS. Therefore, if you're considering quitting THC, it's advisable to consult a healthcare professional to discuss your specific circumstances and explore alternative treatments for your sleep issues.
Finally, be prepared for possible withdrawal symptoms, including increased time to fall asleep, decreased sleep duration, and lower sleep quality. These symptoms may lead some individuals to relapse into THC use, so it's crucial to have a support system in place and seek professional help if needed.
