10 Things You Need to Know About Marijuana and Insomnia

Research has found individuals use cannabis to treat a number of symptoms, with sleep, pain, and anxiety being the most common. However, research is limited (and sometimes conflicting) when it comes to the effect of marijuana on sleep.

It’s complicated! A 1973 study found 20mg of THC (or tetrahydrocannabinol, the primary compound causing the drug’s high) helped individuals fall asleep faster. A 2004 study found that while 15mg of THC acted as a sedative, 15mg of CBD (or cannabidiol, another compound of the drug) appeared to act as a stimulant. Some lab-based sleep studies have found no change in sleep latency or wakefulness after marijuana use.

There's more to marijuana than just THC and CBD. As THC degrades, it converts to CBN (or cannabinol), a chemical that has been found to be an analgesic and which has a sedative effect. CBN is typically found in degraded or oxidized cannabis and, to a lesser-extent, cannabis products such as hashish.

Terpenes (the oils that give cannabis different flavors) can be found in some popular herbal sleep aromatherapy remedies. Linalool is a floral terpene that works to give lavender its scent and flavor. Terpenes can also be found in chamomile and hops.

Although it takes longer to feel the effects of cannabis-infused edibles than smoking or vaping, the effects can last longer compared to consuming marijuana by other methods. This may help you stay asleep for longer, as well.

Just as excessive alcohol consumption can lead to a hangover the next day, marijuana can have the same effect. Furthermore, marijuana that has been treated with pesticides can lead to a more pronounced hangover effect. Drinking plenty of water can help reduce hangover symptoms.

A 2008 study found that marijuana reduced REM sleep, leading to less time spent dreaming and to less-vivid dreams. This might be beneficial for those who suffer regularly from traumatizing nightmares.

Marijuana isn't a magic bullet when it comes to sleep. In fact, even if it does help tackle insomnia symptoms, the symptoms may return if you stop consuming the drug. One study found that up to 76 percent of heavy marijuana users reported disturbed sleep after abruptly quitting marijuana.

Preliminary research suggests that the dronabinol cannabinoid may improve sleep apnea symptoms and that THC may help stabilize respiration during sleep.
