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?
Does Smoking Pot Help You Sleep?
Forget counting sheep—many marijuana enthusiasts toke up before bed to lull themselves into oblivion.
–> But are they really getting good, quality shuteye? Maybe, or maybe not—it depends how often they do it, according to research from Boston University.
In the study, published in the Journal of Addictive Diseases, 98 men and women, mostly in their early 20s, were broken into three groups: daily marijuana users (49 people), nonsmokers (20), and in-betweeners who smoke at least once a month and up to five days a week (29).
Researchers examined sleep patterns in all three groups, using sleep-quality scales, morning and evening surveys, and the Insomnia Severity Index, among others. Overall, the team didn’t find any real difference in the sleep characteristics of sporadic marijuana users and those who abstain. The groups didn’t vary much in terms of daytime sleepiness, either.
But potheads, on average, scored higher on the Insomnia Severity Index—about 20% of nonsmokers were classified as insomniacs, while 39% of daily smokers met the criteria. They also tended to sleep fewer hours, get poorer-quality sleep, and feel less restored than other groups. Women also had a harder time getting high-quality shuteye, but that wasn’t unexpected—insomnia is more common in women than men.
That having been said, if you or your friend swears by weed’s ability to help you fall and stay asleep, you’re not exactly wrong, either. “Sleep disturbance, which is common in this age group, may not be increased by nondaily use,” the authors said in a press release. In other words: toking up every once in a while can help.
Bottom line: Marijuana’s influence on sleep is similar to alcohol’s, the researchers say. It can help pull you under and get a consistent, continuous sleep cycle if you use it once in a while. Make a habit out of smoking, however, and it’ll start to have the same effects of alcoholism on sleep, meaning you could become restless at night or have difficulty falling and staying asleep.
Something else to note: “It remains possible that the [insomnia] scores might have been higher in the daily marijuana users because marijuana was contributing to anxiety, which in turn may have exacerbated the severity of insomnia,” the researchers said.
Then again, it might not just be the pot. Remember, studies like this one track correlation, not causation. So while the study suggests that smoking marijuana every day is associated with lower-quality sleep, it could also be the reverse—that is, people with chronic sleep problems are more likely to smoke every day to try and wind down.
The researchers admit as much: People with anxiety may be heavier users of marijuana because they’re trying to self-medicate and fix their sleep problems, they said. Speak to your doctor if you find your anxiety is hurting your ability to sleep and overall health.

As with alcohol, a puff of marijuana every now and then can help lull you to sleep. But toke up every day, and you’re looking at some restless nights, a new study says.
