Can Weed Cure a Hangover?
Jack swears by smoking weed to treat a hangover. The first time he tried it was in college as a freshman. He’d been drunk before, and he’d been high before, but after one especially rough night, his world-wise roommate told him weed could blunt his aching hangover.
They couldn’t smoke in the dorm, so they went to his roommate’s car. “Almost immediately I wasn’t focused on feeling bad, just being high, and it felt like my headache and upset stomach were gone,” he says. It also gave him an appetite while recovering. Even today he turns to the green after a night of over-drinking.
Jack’s roommate wasn’t a medical pioneer. Weed has been prescribed—and debated—as a hangover treatment going back generations. Nowadays, plenty of weed smokers testify it’s helped them recover from a hangover, with multiple threads on Reddit filled with users praising the technique. “They don’t call it THC for nothing,” says one, “because it’s The Hangover Cure.” Others are more skeptical, saying marijuana might just exacerbate a hangover headache, even if it’s worked before, and worrying that it might cause anxiety or paranoia, or lead to vomiting.
What Mixing Weed and Alcohol Does to Your Mind
There’s also a healthy debate over whether it’s better to smoke or take an edible, and theories about the right choice between sativa and indica, depending on your symptoms. Some warned of the dreaded crossfade that happens when you combine weed and alcohol (“If you are still drunk, don’t smoke”), while others wondered why anyone would drink at all when they could be smoking weed instead.
Beyond street-level anecdotes, though, what does scientific research say about smoking dope to treat a hangover? Does it actually work? Is it any better than the myriad other dubious hangover cures out there?
“There’s actually not a lot of study on this,” said Kent Hutchison, a professor of psychology and neuroscience at the University of Colorado in Boulder. He’s studied substance use and cannabis for years, including work on the National Academy of Sciences committee that produced a comprehensive study on the effects of cannabis.
He also said there hasn’t been much study on hangovers in general, which makes the question doubly tricky to answer. But looking at how alcohol leads to a hangover, he said, can help us theorize how smoking weed might help.
Alcohol makes you urinate, which can lead to dehydration; produces an inflammatory response in your immune system; irritates the stomach lining, often provoking nausea or vomiting; lowers your blood sugar, which can make you feel fatigued or jittery; and expands your blood vessels, which can cause headaches.
Many of these problems can be addressed with drinking water and eating food, even when you feel sick. But Hutchison noted that there are three areas in which weed might be particularly helpful. There’s evidence that smoking cannabis can quell nausea and alleviate anxiety. As many smokers can attest, those effects may help you better cope with the day after a night of hard drinking—-it’s just that research hasn’t yet caught up with the folk remedies. Most of what we know about weed and hangovers comes from anecdotal evidence. “It’s true of so many questions around marijuana,” said Hutchison.
Hutchison pointed to another potentially helpful effect of weed: pain relief. Right now, there’s anecdotal evidence to suggest it can help with headache disorders, as well, but not enough clinical study to prove it, according to a 2017 review article in Cannabis and Cannabinoid Research.
Everything You Need to Know About Using Weed for Headaches
There’s some evidence it works best as a headache treatment when you get the combination of THC and CBD, rather than using them separately. Without more study, though, researchers can’t be certain under what circumstances it’s helpful, including for hangovers. “We don’t really know the underlying mechanisms by which marijuana might relieve pain,” Hutchison said. “It’s better to know the real underlying mechanism.”
However cannabis can help with your hangover, it’s important to note that it’s not curing anything so much as letting you live with the consequences of too much drinking while your body recovers. “Marijuana treats the symptoms,” said Elaine M. Burns, naturopathic medical doctor. She’s long advised patients and doctors about using weed therapeutically. The best ways to deal with a hangover, she said, are “A, avoid it begin with, then B, treat the symptoms.”
For A, she offered the usual tips—drink a glass of water between every drink, for example, and don’t overdo it. But let’s say you’ve already botched things and wake up with pounding headache, dry mouth, dizziness, and upset stomach. In that case, Burnes recommended trying some weed alongside more conventional, proven measures. “It’s about rehydrating,” she said, “with water and electrolytes.” Magnesium supplements can be useful, as well as Emergen-C packets, which provide vitamin C and potassium, as an alternative to Gatorade, which contains a lot of sugar. The very best solution to the dehydration problem, she said, is an IV drip and some magnesium.
When it comes time to spark up (or however you get your weed), remember that you’re trying to treat your specific symptoms—choose your strain and method of delivery wisely. Burns noted that THC and CBD both seem to help with pain relief, while CBD helps more with anxiety. Indica strains have more CBD, so take that into account.
About the most we can say with certainty is that you’ll probably feel better while you’re high, recovering from your previous bad decisions, and honestly, it probably won’t hurt. But right now, the science around cannabis is largely unsettled—we’re still in unfamiliar territory, grasping around with anecdotal evidence. If you’re going to use weed to treat a hangover, congratulations, you’re part of the collective experiment.
Cannabis can quell nausea, alleviate anxiety, and dull pain—so we looked at the evidence for it as a hangover cure.

You may associate a hangover with alcohol, but it is possible for marijuana to have similar effects the next day. The difference between an alcohol hangover and a weed hangover lies in the symptoms. While nausea, dehydration, and insomnia are commonly experienced among those with alcohol hangovers, the hangover effects of too much cannabis may differ.
Here you’ll learn all about the causes and symptoms of weed hangovers, what the experts say on the subject, how to treat weed hangovers , and how to prevent them.
What is a weed hangover?
Weed hangovers occur when you consume more than your personal limit of marijuana. Only you know exactly what that means for your body as tolerance levels vary greatly from one individual to another. Some other factors that influence whether you get a hangover and what the severity will be include the strain you consumed and the tetrahydrocannabinol (THC) content. Cannabis with higher levels of THC makes hangovers more likely, especially if you have consumed beyond your tolerance level.

Further, you are more likely to experience a hangover if you have consumed edibles as they metabolize slowly in the body and may still be active the next morning. A pot brownie or cannabis cookie, then, may cause more hangover symptoms than a joint. If you are making edibles, be sure to stick to a recipe that won’t push your limits. Marijuana smoking or vaping, overall, is less likely to lead to a hangover, although the possibility does exist.
Common weed hangover symptoms may include:
- Brain fog and inability to focus
- Dull, persistent headache
- Dry, itchy eyes
- Grogginess or fatigue
- Cottonmouth (but not systemic dehydration as occurs after drinking too much alcohol)
- Sensitivity to bright lights and loud noises
- Lingering sensation of being high
What causes weed hangovers?
Overconsumption of cannabis, particularly strains high in mood-altering THC, is the main cause of a marijuana hangover. Strains that contain close to 20% or more THC are the most likely culprits. Some of these THC-heavy strains include White Fire OG, Sour Diesel, Chemdog, and, not surprisingly, Amnesia Haze.
Other lifestyle factors may also affect how you feel the day after cannabis use. A poor diet and lack of exercise can make someone more susceptible to feeling ill after a night of indulgence. The healthier your lifestyle, the more likely it is for your body chemistry to be in balance and have the ability to stave off hangovers.
Finally, how often you consume marijuana could influence the likelihood of a hangover. Regular cannabis consumers may want to cut back on their usage and practice moderation. For example, someone who is consuming marijuana daily may want to try using every other day or exclusively on weekends to keep hangovers at bay and potentially eliminate them. Changing the time of day you consume cannabis is another possible experiment. Try consuming early in the evening rather than late at night and see if there is any change.
Research on weed hangovers
A number of older scientific studies offer insight into the residual effects of smoking weed and the associated biological processes. For example a 2006 study published in the journal “Experimental Biology and Medicine” showed that marijuana use decreases saliva secretion , which can explain dry mouth. A lack of saliva in the mouth does not, however, lead to or signify full body dehydration, a departure from the aftermath of over consuming alcohol.
Other studies have fueled debate as to whether a weed hangover is a real phenomenon or a figment of the imagination. A 1998 study published in the journal “Pharmacology, Biochemistry, and Behavior” found the effects of smoking marijuana to be minimal with an increase in heart rate as the most significant acute result . However, minimal effects were present the following day. The authors concluded that smoking a marijuana cigarette did not have a significant impact on the body or brain in subsequent days. Notably, this study had a small sample size of just 10 individuals, all of whom were men, so these findings may not prove accurate across a wider and more diverse population.
An even earlier study published in 1985 in the journal “Drug and Alcohol Dependence” found similar acute signs, such as increased heart rate, along with altered performance in behavioral tasks . These tasks included sorting cards and free recall. Researchers noted that there were some possible hangover indications, but, “the precise nature and extent of these effects, as well as their practical implications, remain to be determined.” The subjects, all male as in the 1998 study, received either placebo joints or marijuana cigarettes containing a low level of THC (2.9%). The results could have been quite different if the THC content had been higher or, again, if a wider and more heterogeneous sample population had been tested.
Very little additional research exists on this topic. Clearly,fresh studies and perspectives are needed.
Research aside, you know your body and you know if you are experiencing a hangover. So, if a marijuana hangover hits, what can you do to recover from it?
How do I get over a weed hangover?
Though you might be tempted to stay in bed all day, the most effective way to shake off the unwanted after effects of excess cannabis consumption is to move your body. Another key component of the recovery process is healthy food, along with hydration, relaxation, and if you are so inclined, meditation.

Here are five healthy home remedies to help you conquer a weed hangover and feel better in the process.
- Get out in the fresh air and take a brisk walk. Breathe deeply as you walk, flooding the brain and lungs with a new supply of oxygen, and clearing away any mental fogginess. Walk for at least 20 minutes and up to an hour to maximize the positive effects.
- Roll out a yoga mat and do a few gentle stretches while focusing on cleansing, deep breaths. Back bends that open the chest and allow the body to take in more oxygen are especially beneficial. A brief five-minute period of meditation and visualization can round out your yoga practice and leave you feeling invigorated.
- Eat a power breakfast, whether that means a homemade turkey omelet or a vegan bowl of steel-cut oatmeal and fresh berries. Whatever you choose, keep it natural and nourish your body with nutrient-rich food.
- A tall glass of water is a basic way to combat any hangover, but you might want to elevate it to the next level with a caffeine infusion. Coffee or tea can help stimulate the mind and give your body a much needed energy boost. If a headache persists, lemon water with two Tylenol or another pain reliever could offer quick relief.
- If you can’t bring yourself to eat or exercise, simply step into a cool shower and refresh your senses with soothing water. The pressure from the water can have therapeutic effects, massaging and easing tight muscles.
Keep eliminating the hangover throughout the day by practicing healthy habits including balanced eating and moderate exercise. When the sun goes down, consider going to bed a bit earlier than usual, and abstain from consuming or smoking marijuana until you’re feeling in peak condition. While you’re on the mend consider applying CBD oil to affected areas such as the temples or neck if you feel any lingering discomfort. Topical CBD preparations can relieve pain in some individuals.
Can I prevent a weed hangover?
The best way to prevent a marijuana hangover is to know your personal limits and adhere to them. Smoking rather than consuming edibles is another strategy that may work. In addition, seek out strains that are lower in THC, such as Euphoria, an indica-dominant variety which caps out at a manageable 9% THC. Easy Bud, clocking in at around 12% THC content, is another good choice. There are many strains geared towards beginners and others who may be more sensitive to the effects of THC. The higher the ratio of cannabidiol (CBD) to THC, the less likely you are to feel hungover.
If you are using marijuana alongside alcohol and tobacco, try curbing the use of the latter two products and see if that makes a difference. If you continue to feel unwell after using marijuana, consult with your healthcare provider to see if there could be an underlying medical issue.
In the end, knowing and honoring your body’s boundaries is the best way to prevent marijuana hangovers while enjoying the many potential benefits of the plant.
