Cannabis for Sleep: Does It Work?
Cannabis is known for its wide-ranging therapeutic benefits, including easing and assisting health conditions that range from pain relief to mood disorders. But what about its influence on sleep?
The Effects of CBD
Cannabis contains numerous cannabinoids—naturally occurring compounds responsible for producing the effects cannabis is commonly used for. A popular cannabinoid is cannabidiol, or CBD, which is found in many cannabis-based products like tinctures, oils, and gummies.
All cannabinoids, including CBD, interact with our endocannabinoid system (ECS). This cell-signaling system is responsible for controlling and regulating many of our bodily processes, including our mood and metabolism (1). When CBD interacts with ECS receptors in our brain and nervous system, users can experience specific effects.
In particular, CBD works to ease our nerves, relieve pain, and reduce the symptoms of anxiety and depression (2). The compounding effects of CBD can be highly therapeutic and can positively affect our sleep quality.
Research supports this claim, with a study concluding cortisol levels decreasing after taking moderate amounts of CBD oil (3). Cortisol is a stress hormone, and in patients with insomnia, it can peak in high amounts. Another study found that just 25mg of CBD was enough to improve sleep quality and decrease anxiety symptoms (4).
How to Take Cannabis for Sleep
As mentioned earlier, CBD is available in various forms. It’s often taken in oils or tinctures as users can regulate the amount, and due to sublingual absorption, effects occur faster. However, due to the earthy aftertaste, many prefer the convenience and taste of CBD gummies.
When taking CBD for sleep, start slow (a few drops) and work your way up, increasing the amount based on your preferences. You may like to take it an hour before you head to sleep, but you can also play around with the dosage, taking it during the day. It’s also important to check in with your health professional before starting.
Tetrahydrocannabinol (THC) is another popular cannabinoid that can be found in some cannabis-based products. However, THC is psychoactive and can create a high (5). Due to its stimulating nature, THC-based products are not recommended for sleep.
Side Effects
Generally, cannabis-based products containing CBD are well-tolerated amongst most of the population. However, care should still be taken, especially if trying these products for the first time. Side effects (6) include:
Dry mouth
Fatigue and drowsiness
Increase in appetite
Changes in mood
Changes in bowel habits
These side effects should subside after the initial period, but talk to your health professional if they persist.
Bottom Line
Cannabis has many health benefits due to its cannabinoids, including CBD. CBD effectively improves sleep quality, although more long-term studies are needed before cannabis-based products can completely replace traditional sleep medication.
