Why Does Smoking Cannabis Make You Feel Tired?

Several studies could point towards a more complex link between cannabis and the feeling of tiredness experienced after smoking.

Every regular cannabis smoker has experienced drowsiness, lethargy, or a general lack of motivation after or while smoking weed. Many will shrug this off as the nature of a specific strain, while some may find these attributes desirable—especially if insomnia is an issue. Newly published research may point to excessive cannabis consumption as a cause of long-term feelings of drowsiness or laziness. For those choosing to use recreational cannabis to avoid the hangover or comedown of other drugs, this strategy may prove somewhat ineffective.

DOES SMOKING WEED MAKE YOU LAZY?

A strong indica strain will undoubtedly knock you down onto the sofa, where, let’s be honest, not a lot gets done. For a vast majority, this is a desirable trait, and the reason users choose indica strains to begin with. If you enjoy smoking cannabis and live an otherwise active lifestyle, then smoking will not suddenly make you lazy or lethargic for the long-haul. The answer to why marijuana makes us feel drowsy and in turn, less motivated, could actually come down to the way THC is absorbed and subsequently interacts with the neurotransmitter dopamine.

IS THC TO BLAME?

Published by The National Institute For Biotechnology Information, the following research points to an apparent reduction in dopamine levels as a result of excessive cannabis use. In summary, the study found that heavy smokers of cannabis, those who were borderline dependent, produced significantly less dopamine than that of non-smokers or light users.

Using a sample group of 19 frequent cannabis smokers and 19 non-smokers, this study stands out because, although similar tests have been undertaken before, none have included active smokers. Importantly, the frequent cannabis smokers had all admitted to suffering from psychotic-like symptoms when smoking, a sign of excessive use.

Michael Bloomfield, PhD stated that “After a period of time, your brain cells aren’t able to make as much tyrosine hydroxylase, an important enzyme that’s a key component in making dopamine”.

This stunting of chemical processes is a result of the way the cannabinoid THC interacts with our body’s natural endocannabinoid system.

WHY IS DOPAMINE IMPORTANT?

With heavy THC consumption seemingly impacting dopamine levels, what does the release of dopamine mean to our bodies? Dopamine acts as a regulator for effort threshold—how much effort is required to complete a task and what the rewards are. Those with higher levels of dopamine are more likely to undertake functions that require energy. Dopamine also plays a role in giving us that “rewarding” feeling when taking part in pleasurable activities like sex, eating, and exercise. If the level of dopamine released during these activities is reduced, then it stands to reason that motivation to perform would also decrease.

ARE TERPENES AS IMPORTANT AS CANNABINOIDS?

Cannabis is a complex organism. Alongside key cannabinoids THC, CBD, and CBN, cannabis contains terpenes. These molecules provide the vast array of aromas we have come to love. More than that though, theorists suggest that terpenes work in unison with cannabinoids to boost or enhance the relative effect.

A 2011 study examined the impact of the terpene myrcene. Myrcene is known for giving cannabis a musky, mango-like aroma. Furthermore, myrcene was found to induce a hypnotic effect, as well as display muscle-relaxant properties. Combined with THC, these two compounds work in conjunction to make individuals feel tired. Previous studies have found similar attributes with the terpene linalool, although this time, linalool partnered with CBD to produce a drowsy effect.

DOES CANNABIS IMPACT HOW WELL WE SLEEP?

Playing a potential role in reducing dopamine levels, what else can smokers expect THC to impact? Well, the answer may reside in the land of Nod. Anecdotal evidence from users would suggest we sleep better after smoking cannabis. Many have reported that we sleep so much better that the feeling of drowsiness can be hard to shake the morning after. With so many swearing by cannabis as a sleep aid, what scientific research is there to support this thesis?

Two studies, the first conducted in 1975 and more recently in 2004, delivered relatively inconclusive results. Both noted a decrease in REM sleep (rapid eye movement sleep phase), but our deep sleep phase remained roughly the same. It could be surmised that a reduction in REM sleep could result in the feeling of increased tiredness experienced the morning after smoking cannabis.

Both investigations have something in common—the vast number of variables yet to be explored. The results are still too inconclusive to draw a satisfactory conclusion. Instead, further studies will be needed, in which sample size, age of participants, strains smoked, and any previous medical issues, etc are taken into account. One thing is for sure; there does seem to be some correlation between smoking cannabis and the feeling of tiredness. The exact cause of this phenomenon is still unknown.

HOW TO COUNTERACT TIREDNESS AFTER SMOKING

What does that mean for us? Well, for now, the usual rules apply. Enjoy cannabis as you usually would, while being aware that every user will experience symptoms differently. If you do find yourself having periods of drowsiness or lethargy the morning after smoking cannabis, then a few simple steps can be taken to counteract this.

These include selecting a strain with less THC, smoking less, and hydrating. And of course, exercise, a healthy diet, and good ole coffee can help shake the fatigue as well; be it a result of smoking weed or not.

Numerous users will have experienced drowsiness when smoking cannabis. Is this a natural reaction, or is there a long-term impact on our bodies?

    Falling asleep is as easy as laying down and closing your eyes. But about 40 million Americans have some sort of sleep issues and marijuana can help, but first, let’s explain exactly why does marijuana make you sleepy.

    The Centers for Disease Control and Prevention considers sleep apnea and other related disorders as a dangerously hidden public health issue. According to the CDC, “persons experiencing sleep insufficiency are also more likely to suffer from chronic diseases such as hypertension, diabetes, depression, and obesity, as well as from cancer, increased mortality, and reduced quality of life and productivity.”

    An estimated 10 million Americans have a prescription for Ambien or some other pharmaceutical sleep medication and 4 percent of adults report that they have taken a sleeping pill or sedative in the previous month. Some of the more common side effects for these pills include:

    • Daytime drowsiness, dizziness, weakness, feeling “drugged” or light-headed
    • Tired feeling, loss of coordination
    • Stuffy nose, dry mouth, nose or throat irritation
    • Nausea, constipation, diarrhea, upset stomach
    • Headache, muscle pain

    As more and more states move to legalize cannabis, more of us are looking at the herb as an alternative to pharmaceuticals. Studies have shown that cannabis can improve the duration and quality of sleep. A 1973 study suggests that THC reduces the amount of time it takes those with insomnia to fall asleep. Another study found that those that regularly used THC fell asleep faster.

    Before you grab your bong, here are a few things you should know:

    Know The Difference Between Indica And Sativa

    Most regular cannabis consumers know that Indica strains provide more of a “body high.” These strains are preferred if you are looking to relax and sleep. Sativa strains are provide a more upbeat experience and can often interfere with sleep.

    Ask your budtender for help identifying “sleep strains.” You may have to do a little of trial and error before you find the right strain for you.

    The Cannabis Combo

    The science of why cannabis promotes sleep is not entirely clear, but some research suggests that the terpenes in cannabis are doing the work. Terpenes are the aromatic compounds in marijuana and they interact with your body in favorable ways.

    The terpenes found in lavender and chamomile both promote sleep. Working in combination with cannabis, a soak in a lavender-infused bath or a cup of chamomile tea before bed may work. Aromatherapy is another option.

    Beware Of The Edible “Hangover”

    Edibles are another great way to get a good night’s sleep. These typically pack a stronger punch and stay in your system much longer than smoked marijuana.

    The downside of edibles? Since the cannabinoids are processed differently and stay in your system longer, you may wake up still feeling the effects of the dose. Typically, the high dissipates after a hot shower and a cup of coffee or tea.

    PTSD Sufferers: Take Note

    Studies have also found that cannabis is effective for treating nightmares in military personnel with PTSD. Many veterans use cannabis as a sleep aid in order to keep the nightmares at bay. If you suffer from PTSD or anxiety, cannabis may work for you.

    Final Thoughts

    There are now 29 states that have a medical marijuana program, but not one include sleep disorders as a qualifying condition. Why? There simply is not enough research. But if you want to steer clear of sleeping pills, cannabis may help.

    Your body and your brain need seven to nine hours of sleep. Your health depends on it.
