Cannabis is widely used as a sleep aid, with THC-infused drinks, edibles, and other swallowed or sublingual options considered safer methods with fewer side effects. THC has sedative effects and can help people fall asleep faster, especially if anxiety or pain is making it difficult to fall asleep. However, THC decreases the time spent in rapid eye movement (REM) sleep, which is important for overall sleep quality as it is when dreaming, processing emotions, and cementing new memories occur. While THC may help with sleep in the short term, long-term use may negatively impact sleep quality and cause other side effects. Additionally, THC comes with a psychoactive high, which may be undesirable for some people. CBD, on the other hand, is non-psychoactive and is more closely associated with sleep and relaxation, as it calms the central nervous system and boosts sleep-promoting compounds. The effects of THC and CBD together may depend on the dose and timing, and it is important to consult with a healthcare professional to understand the potential benefits and risks.

What You'll Learn
THC's impact on REM sleep
THC, the primary psychoactive component of cannabis, has been shown to decrease REM sleep. REM sleep, or rapid eye movement sleep, is the stage of sleep where we do our most active dreaming, and our brains process emotions and memories. While THC has sedative effects, helping users fall asleep faster, it also reduces the amount of time spent in REM sleep. This can have benefits for people with PTSD, as it can decrease or stop nightmares, a common and disturbing symptom. However, too much suppression of REM sleep is not healthy.
Several studies have found that THC is linked to reductions in REM sleep and increases in deep, slow-wave sleep and the lighter stages of non-REM sleep. THC decreases sleep latency, helping users fall asleep more quickly. However, this can lead to next-day grogginess, and some studies have shown that in the second part of the night, users may experience more awakenings and fragmented sleep.
The effects of THC on sleep may depend on the dose and timing. Synthetic forms of THC have shown potential in treating sleep apnea and improving sleep for people with chronic pain. Short-term use of THC may be beneficial in helping users fall asleep faster, but health experts generally do not recommend long-term use of sleep aids, including THC, as they can negatively impact sleep quality and cause other side effects.
THC may also have different effects on occasional versus daily users. Daily users are more likely to report sleep problems than occasional users or non-users. Occasional users report fewer sleep issues than daily users and non-users.

Short-term vs long-term use
While short-term cannabis use may help people fall asleep faster and improve overall sleep quality, long-term use may negatively affect sleep. Research suggests that THC, the main psychoactive component of cannabis, decreases the amount of time spent in REM sleep, which is important for healthy cognitive and immune functioning. Over time, individuals may develop a tolerance to THC, requiring higher doses to achieve the same sleep-inducing effects, which can disrupt the natural sleep cycle and lead to dependence.
In contrast, CBD, another prominent cannabinoid in cannabis, is non-psychoactive and has been associated with anxiolytic and sedating effects. While CBD does not significantly impact REM sleep like THC, it has been linked to improved sleep efficiency and sleep duration, particularly at higher doses. However, low doses of CBD and high doses of THC have been associated with negative sleep outcomes.
The effects of cannabis on sleep may also vary depending on the individual and their specific conditions. For example, cannabis may be more effective for individuals with chronic pain, restless leg syndrome, PTSD, or multiple sclerosis, as it can help them fall asleep faster and improve overall sleep quality. However, it is important to consult with a healthcare professional before considering cannabis as a sleep aid to discuss potential benefits and risks based on individual medical history.
Overall, while cannabis may provide short-term relief for sleep issues, long-term use is generally not recommended due to its potential negative impact on sleep quality and other possible side effects.

THC dosage
While there is some evidence that THC can help with sleep, there is limited high-quality evidence to support its use as a sleep aid. The effects of THC on sleep may depend on the dose, timing, and method of ingestion.
THC has been shown to decrease the amount of time spent in rapid eye movement (REM) sleep, when people spend more time dreaming, processing emotions, and cementing new memories. This may have benefits for people with PTSD, as nightmares are a common symptom. Synthetic forms of THC have been shown to decrease nightmares and improve sleep for people with PTSD. THC may also help with sleep apnea and chronic pain. However, THC may not improve sleep architecture in terms of the time it takes to fall asleep, how long one sleeps, or the amount of time spent in REM sleep.
The dosage of THC that is favourable may depend on the individual and the method of ingestion. The effects of THC are felt almost immediately when smoking or vaping cannabis. Sublingual tablets, tinctures, and other methods that are absorbed directly into the bloodstream may take effect within minutes. Edibles and drinks must pass through the digestive tract and may take 1 to 4 hours to take effect. The dosage may also depend on the condition being treated. For example, the therapeutic dose range for dronabinol, a synthetic form of THC, is 2.5 mg to 20 mg/day for most conditions, with doses up to 40 mg being effective for treating chemotherapy-induced nausea. Doses of THC above 20-30 mg/day may increase adverse events and tolerance without affecting efficacy. In clinical studies, smoked or vaporized medical cannabis use ranged from 75 mg (9.4% THC) to 3200 mg/day (1%-8% THC), corresponding to a range of consumed THC from as low as 2.5 mg/day to greater than 120 mg/day.
It is important to note that the use of THC or cannabis for sleep should be done under the guidance of a healthcare professional. While it may provide short-term benefits, long-term use may negatively impact sleep quality and cause other side effects. The brain and body can also develop a tolerance to THC, requiring higher doses to achieve the same effects. Abrupt discontinuation of THC after long-term use can lead to sleep problems, including insomnia and the return of nightmares.

THC-infused edibles
THC (tetrahydrocannabinol) is the compound in cannabis that produces the feeling of being high. When cannabis is heated, the THC dissolves into an oily liquid along with other chemicals, including CBD (cannabidiol). This cannabis oil can then be used as an ingredient in edibles such as candies, baked goods, and other foods. THC-infused edibles can vary significantly in their THC content, so it is important to read the label and start with a low dose, especially if you are new to THC edibles. It can take up to four hours to feel the effects of THC-infused edibles, so it is important to wait before consuming more.
The legality of THC-infused edibles varies depending on the location and the specific type of THC. In the United States, edibles containing cannabis are not legal under federal law unless they contain very small amounts of THC. However, a growing number of states have legalized marijuana, including cannabis-infused edibles, for medical or recreational use. It is important to check the laws in your specific state or location before purchasing or consuming THC-infused edibles.
Overall, while THC-infused edibles may offer short-term benefits for sleep, there is limited research on their long-term effects. It is always recommended to consult with a healthcare professional before using THC-infused edibles or any other sleep aid.

THC and PTSD
Sleep disturbances are one of the most debilitating symptoms of PTSD. People with PTSD often suffer from insomnia, which can lead to depression and anxiety, making the symptoms of PTSD even worse.
Research has shown that individuals with PTSD, particularly those with heightened hyperarousal symptoms, use cannabis to cope with their condition. In particular, those with more severe PTSD are more likely to use cannabis to improve their sleep. THC, one of the main cannabinoids found in cannabis, has been shown to improve self-reported sleep quality and reduce nightmare frequency in PTSD patients. For example, in a small study, 5mg of THC twice a day as an add-on treatment was found to enhance sleep quality and reduce nightmares in patients with PTSD.
However, it is important to note that the evidence base for the effects of cannabis on sleep, and in PTSD patients specifically, is limited. While cannabis may provide short-term relief, long-term use may lead to tolerance, and even cause long-term sleep problems. Large THC dosages have been shown to be detrimental to sleep. Additionally, cannabis does not cure PTSD, and symptoms may become more intense once the effects of the drug wear off.
If you are considering using medical cannabis to treat PTSD, it is important to consult with a doctor about delivery methods, dosages, and strains. Different strains offer different effects, and it is necessary to determine the ratio of THC to CBD that is most effective in promoting therapeutic effects while minimizing adverse effects.
