What Happens When You Sleep High? The Effects Of Marijuana On Sleep

For many, the idea of using marijuana as a sleep aid is an enticing one. The relaxing, sedating effects of cannabis seem like they could be the perfect natural remedy for insomnia and other sleep issues. But what really happens when you go to bed high? Does marijuana actually improve sleep quality, or could it be doing more harm than good in the long run? Let’s delve into the complex relationship between weed and catching some Z’s.

The Potential Benefits Of Marijuana For Sleep

Potential Benefits Of Marijuana For Sleep

One of the main reasons people turn to marijuana as a sleep aid is because of its observed sedative effects. Tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, is known to have a calming, sleep-inducing influence. Some studies have suggested that THC can decrease the time it takes to fall asleep and may even increase overall sleep duration.

Additionally, marijuana has been touted as a potential treatment for conditions that can disrupt sleep, such as chronic pain, anxiety, and post-traumatic stress disorder (PTSD). By alleviating these issues, cannabis may indirectly improve sleep quality for some users.

However, it’s important to note that much of the research on marijuana and sleep is still in its early stages, and the results have been mixed. While some studies point to potential benefits, others have found no significant improvements in sleep quality or even suggest potential drawbacks.

The Downsides Of Sleeping High

While the sedative effects of THC may help you fall asleep faster, research suggests that marijuana can negatively impact the overall quality of your sleep. One of the primary concerns is the potential disruption of the sleep cycle, particularly the rapid eye movement (REM) stage.

REM sleep is crucial for cognitive function, memory consolidation, and emotional processing. Studies have shown that marijuana use can suppress REM sleep, leading to shorter REM cycles or even complete REM sleep deprivation. This can leave you feeling groggy and unrested the following day, despite potentially sleeping for a longer duration.

Additionally, marijuana use before bed has been linked to an increase in sleep disruptions, such as waking up frequently throughout the night. This fragmented sleep can further reduce the restorative benefits of a full night’s rest.

The “Weed Hangover” And Other Morning-After Effects

Even if you manage to fall asleep quickly after consuming marijuana, the effects of the drug can linger into the next day. Many regular cannabis users report experiencing a “weed hangover” the morning after using, characterized by grogginess, brain fog, and impaired cognitive function.

This hangover-like state can be attributed to the residual effects of THC on the brain, as well as the potential disruption of REM sleep. It can make it challenging to perform tasks that require alertness, focus, and quick reaction times, such as driving or operating heavy machinery.

Furthermore, some research suggests that the sedative effects of marijuana may wear off over time, leading to a potential rebound effect. This means that after initially helping with sleep onset, chronic marijuana use could actually exacerbate insomnia and disrupt sleep patterns in the long run.

The Risk Of Dependence And Withdrawal

While marijuana may not be as physically addictive as some other substances, it does carry a risk of psychological dependence, especially when used as a sleep aid. When you rely on cannabis to fall asleep, your body can become accustomed to the presence of THC, making it increasingly difficult to sleep without it.

If you suddenly stop using marijuana after developing this dependence, you may experience withdrawal symptoms, including insomnia, irritability, and anxiety. This can create a vicious cycle where you feel compelled to use marijuana again to alleviate the withdrawal-induced sleep issues, further reinforcing the dependence.

Potential Interactions And Contraindications

It’s also important to consider the potential interactions between marijuana and other medications or substances. For example, combining cannabis with alcohol or certain prescription drugs can amplify the sedative effects, leading to excessive drowsiness and impaired cognitive function.

Additionally, individuals with certain medical conditions, such as lung diseases or heart conditions, may be at a higher risk of adverse effects from marijuana use. It’s always advisable to consult with a healthcare professional before using cannabis, especially if you have underlying health issues or are taking other medications.

Alternative Natural Sleep Aids

If you’re hesitant about the potential drawbacks of using marijuana as a sleep aid, there are several natural alternatives that may be worth exploring:

Melatonin: This hormone regulates the sleep-wake cycle and can be taken as a supplement to promote sleep onset and improve sleep quality.

Valerian Root: This herb has been used for centuries as a natural sedative and may help improve sleep quality and reduce the time it takes to fall asleep.

Chamomile Tea: Chamomile is a mild sedative that can promote relaxation and may help alleviate insomnia and other sleep disturbances.

Lavender: The calming aroma of lavender has been shown to improve sleep quality and promote relaxation. You can use lavender essential oils, sachets, or even lavender-infused tea.

Meditation and Relaxation Techniques: Practices like deep breathing, progressive muscle relaxation, and mindfulness meditation can help reduce stress and anxiety, promoting a more restful sleep.

Exercise: Regular physical activity during the day can help regulate your sleep-wake cycle and improve sleep quality, but avoid strenuous exercise close to bedtime.

Sleep Hygiene: Establishing good sleep habits, such as maintaining a consistent sleep schedule, creating a sleep-conducive environment, and avoiding stimulants like caffeine close to bedtime, can greatly improve your ability to fall and stay asleep.

It’s always advisable to consult with a healthcare professional before trying any new supplements or remedies, especially if you have underlying medical conditions or are taking prescription medications.

Seeking Professional Help For Sleep Issues

If you’re consistently struggling with sleep issues, whether related to marijuana use or not, it’s important to seek professional help. Chronic insomnia or other sleep disorders can have serious impacts on your physical and mental health and may require medical intervention or therapy.

A sleep specialist or healthcare provider can help diagnose the root cause of your sleep problems and recommend appropriate treatments or lifestyle changes. In some cases, cognitive-behavioral therapy for insomnia (CBT-I) or other forms of therapy may be beneficial in addressing the underlying issues contributing to your sleep disturbances.


While the idea of using marijuana as a sleep aid may seem appealing, the reality is that the relationship between cannabis and sleep is complex and not without potential drawbacks. While marijuana may help some individuals fall asleep faster, it can also disrupt the sleep cycle, reduce sleep quality, and potentially lead to dependence and withdrawal issues.

It’s important to weigh the potential benefits against the risks and consider alternative natural sleep aids or professional treatments for chronic sleep issues. As with any substance, moderation and caution are key when using marijuana, especially for those with underlying medical conditions or taking other medications.

Ultimately, the decision to use marijuana as a sleep aid should be made in consultation with a healthcare professional, taking into account your individual circumstances and health needs. A good night’s sleep is essential for overall well-being, and finding safe, effective solutions should be a priority.
