brain fog from weed

How to Conquer a Weed Hangover

Despite some debate over their validity, weed hangovers are likely real. While research on the subject is limited, anecdotal reports suggest that smoking marijuana can trigger next-day symptoms in some people.

Despite the similar names, weed hangovers aren’t quite the same as those brought on by alcohol. And for many, weed hangovers tend to be more tolerable than alcohol-related ones.

Common symptoms of a weed hangover include:

  • fatigue
  • lethargy
  • brain fog
  • dry eyes and mouth
  • headaches
  • mild nausea

Read on for tips on how to deal with these effects and to learn more about the debate within the medical community over whether weed hangovers are indeed a thing.

A weed hangover will typically go away on its own. There isn’t much you can do for an immediate fix, but these tips can offer relief:

  • Stay hydrated. The most important thing you can do before, during, and after weed use is drink enough water. This will help relieve symptoms such as headaches, dry mouth, and dry eyes.
  • Eat a nutritious breakfast. Opt for a healthy, balanced breakfast the morning after weed use. Try a small serving of whole-grain carbohydrates along with a lean source of protein and healthy fat.
  • Take a shower. A shower can help you to feel refreshed and hydrated the morning after smoking weed. The steam from a hot shower can open your airways.
  • Make some ginger tea.Ginger can help with digestive symptoms, such as nausea. Add a bit of grated ginger to hot water with lemon and honey to soothe an upset stomach.
  • Drink caffeine. A cup of coffee or caffeinated tea can help you feel more alert.
  • Try CBD. Some anecdotal reports suggest that cannabidiol (CBD) can counteract some of the symptoms associated with a weed hangover. Just steer clear of any preparations containing THC.
  • Take a pain reliever. For a persistent headache, take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol).

If you can, try to take it easy for the rest of the day. With a good night’s rest, you should wake up feeling like yourself again.

If you’re feeling a little off after using weed, it may not necessarily be a hangover that you’re experiencing.

Here’s some other potential culprits:

  • Drinking alcohol or using other drugs while using weed. If you tend to consume other substances while smoking marijuana, they might affect how you feel the next morning.
  • Marijuana withdrawal. If you smoke weed on a regular basis, it’s possible to experience withdrawal symptoms when you aren’t smoking. Symptoms of marijuana withdrawal include changes in mood, insomnia, and difficulty focusing.
  • Lingering effects of weed. How long a weed high lasts depends on factors such as dose, concentration, and delivery method, in addition to your own tolerance and metabolism. Most of the time, a marijuana high lasts between one and four hours.

If at least five hours have passed since you last used weed, and you haven’t had any alcohol or used other substances, you’re likely just experiencing the after effects of weed.

There isn’t much evidence surrounding weed hangovers. Existing studies are often outdated or have major limitations.

Older studies

One well-known study on weed hangovers dates back to 1985. In the study, 13 males participated in a series of sessions that involved smoking either a weed cigarette or a placebo cigarette and then completing a series of tests.

The tests included sorting cards and judging time intervals. When the tests were repeated the following morning, the group that smoked weed cigarettes judged time intervals to be 10 or 30 seconds longer than they actually were.

The authors concluded that, although the day-after effects of smoking weed may be subtle, they probably exist. However, this study’s small sample size and all-male participants are significant limitations.

A 1990 study had similar limitations. It involved 12 male marijuana users who smoked marijuana over one weekend and a placebo over another, then completed a series of subjective and behavioral tests. But these authors concluded that weed didn’t seem to have much of an effect the following morning.

Recent research

More recently, a 2017 study explored perspectives toward medical cannabis among people with chronic pain. One of the self-reported undesirable effects of marijuana was a hangover described as a foggy, non-alert feeling in the morning.

However, the authors of the study did not indicate how many participants reported this effect.

A 2015 review on the use of medical marijuana recommends that healthcare professionals teach patients about the hangover effect. It also recommends describing it as lasting at least one day after the last time marijuana was used.

more research is needed

There are, of course, numerous anecdotal reports of marijuana hangovers, suggesting they are possible. More research needs to be done to understand causes, symptoms, and risk factors associated with weed hangovers as well as recommended self-care.

In addition, most of the studies described above focused on the morning-after effects of smoking a small amount of marijuana. Research exploring the effects of overconsumption is also needed.

The only way to guarantee you won’t have a weed hangover is to avoid weed. Still, there are plenty of things you can due to minimize the negative effects of weed.

  • Avoid smoking weed the night before an important activity. If you tend to experience weed hangovers, try to avoid using marijuana the night before something important, such as an exam or stressful day at work.
  • Take days off. If possible, avoid using weed on a daily basis. Continuous weed use can build up your tolerance, which might eventually trigger withdrawal symptoms in the morning.
  • Limit your use. You might be more likely to experience a weed hangover if you overconsume. Decide on an appropriate quantity before you get high, and stick with that.
  • Try low-THC marijuana. THC is the active ingredient in weed. No one’s totally sure how THC affects weed hangover symptoms, but it’s worth trying low-THC strains to see if they help prevent morning-after symptoms.
  • Use caution when trying a new product. You might find you react differently to weed depending on the dose, concentration, and method of delivery. When trying something for the first time, start with a low dose.
  • Don’t mix it with other substances. The morning-after effects of weed might be more intense if you tend to smoke weed while also drinking or using other drugs.
  • Talk to your healthcare provider about the effects of weed and medication. Remember that any over-the-counter or prescription medication you take can interact with weed. This could affect how you feel in the morning.

Contrary to popular belief, weed can be addictive. The more often you use it, the more likely you are to become dependent on it.

If you regularly experience weed hangovers, they could be a sign that you’re overdoing it. If you’re having a hard time curbing your use, it may be time to reach out to your doctor for help.

Other potential signs of weed misuse include:

  • using it on a daily or near-daily basis
  • experiencing cravings for it
  • spending a lot of time thinking about it or obtaining it
  • using more over time
  • using more than you intended
  • continuing to use it despite negative consequences
  • keeping a constant supply
  • spending a lot of money on it, even when you can’t afford it
  • avoiding situations or places where you can’t use it
  • driving or operating machinery while high
  • trying and failing to stop using it
  • experiencing withdrawal symptoms when you stop

"Weed hangover" is a casual term used to refer to the lingering effects of weed. We'll offer some tips for relief, take a look at the research behind this phenomenon, and give you some guidance on how to prevent them in the future.

Brain fog is one condition which is loosely defined and is not even considered to be a real medical condition. However, it is commonly found to accompany other serious illnesses. Its symptoms include impairment of concentration, affecting memory and clarity of thinking.

Brain Fog Defined

Brain fog is mostly defined as a condition that affects the way one thinks. People who experiences brain fog may feel disconnected and confused. Thinking clearly is almost impossible and the sufferer may feel spaced out.

Other symptoms include short term memory, a shortened attention span and forgetfulness. Often this happens at unexpected times when they feel detached and stuck. Others have reported feelings of cotton balls filling their head, the crown of their head tingling and their vision being somewhat impaired.

Causes of Brain Fog

Brain fog is common and it affects so many people at varying intensities. Although it affects mental clarity, it is different from dementia, depression or anxiety and all other mentally related problems. Its most common causes include the following:

  1. biochemical imbalance
  2. nutritional imbalance/deficient
  3. ingestion of toxic metals
  4. bowel toxicity
  5. adrenalin burnout
  6. thyroid imbalance
  7. yeast levels
  8. hypoglycaemia
  9. food allergies
  10. drugs/medications
  11. viral infection
  12. lack of sleep
  13. chemotherapy
  14. substance abuse

How to Clear Brain Fog

Eat healthy food

Healthy foods can strengthen your immune system. They can boost your body’s immunity against conditions that may cause brain fog. Healthy foods may also help detoxify your body from current day lifestyles which includes eating junk and fast foods and getting exposed to the toxicities of artificial foods.

Eating healthy food may also give your body the right state of mind wherein you get to think clearly and you can push away all negativities caused by physical ailments.

Get some sleep

Sleeping right means getting your body the right amount of rest. Sleeping is known to have restorative power for the body. It helps people gain back the energy they lost during the day. When one keeps a good sleeping pattern, the body may become attuned to the good benefits of sleep. This in return gives you clear mind devoid of fogginess intensified by lack of sleep.

By sleeping, it isn’t just the body that gets to rest; the mind gets a chance to rest as well.


Exercise strengthens the body and helps clear the fog away. Exercising may let the body produce the necessary hormones to keep the brain happy and focused.

Exercise may also foster discipline and focus; two good things to strengthen the mind and keep the brain healthy.


When you scour the internet, you may find various tips on how to detoxify. Some are true, some are not. Some people may react positively to the process while others may not. Anyway, detoxification can purge the body of all toxins that we acquire from food, drinks and the environment.

It’s one of the best ways to diet but it’s also very effective in clearing the fog away. It promotes the elimination of toxins and waste through stimulation of the liver, it rests the organs, improves blood circulation and it refuels the body with healthy nutrients.

After the detox process, you may find yourself clearheaded and with improved memory capabilities. Different detoxification processes involve the following:

  • Replace meal with a smoothie out of fruits and veggies
  • If you do eat, make everything organic
  • Get an intense massage
  • Drink lots of water
  • Instead of coffee, have a cup of green tea
  • Exercise (mentioned above already)
  • Acupuncture
  • If you can, fast for a day or two (not recommended if you have health problems)
  • Avoid pollution
  • Do yoga (will be discussed later)
  • Have superfoods!
  • Try to eliminate medication (if possible)
  • Dry skin brush
  • Say no to processed foods

Get off gluten

Although brain fog is not commonly found in the list of Celiac symptoms, it is said to be associated with gluten products. One remedy is to stop including gluten food in your diets. This may include bagels, breads, dumplings, muffins, noodles, wheat scones, pizza, and the list goes on. You can try to cut down your gluten intake or get rid of it from your diet.

Read and Write

Reading and writing helps exercise the brain. Exercising the brain can make it strong. When the brain is strong you have more ability to avoid the tendency of getting confused and zoning out while in the middle of a task. Challenge yourself every week. Read books with varying levels of difficulty. Then write about your opinion on the book you’ve read. Analyse your thoughts. Analysis of things helps you work out your brain. Or blog about it. Blogging what you’ve read is a good way to let out your thoughts.

De-stress, Meditate

Often, stress can cause distraction. It can occupy your mind and can even erase all important matters from your brain causing you to forget your commitments. So if zoning out happens every time you’re stressed, then maybe it’s time you find a way to de-stress. One method? Meditation.

Do yoga. Yoga is an ancient practice used to clear the mind and to help balance and flexibility. It also helps to strengthen your mind. Try meditating on your negative thoughts. Clarify those thoughts. Focus on your inner being and declutter. That way you may keep focus on the things you need to do, and avoid zoning out.

Take supplements

Do you know that there are supplements that can strengthen your mind? There are supplements that can support your brain and help strengthen your mental clarity. These include supplements of vitamin b12, vitamin D and Omega-3. Omega-3, as we already pointed out in our previous article, may help in brain health and has been found to reduce the likelihood of dementia.

Eliminate distractions, De-clutter

Your physical environment may affect the way you think. So instead of working at a cluttered desk, throw away all the unnecessary things. If you have a TV in the bedroom, unplug it, it can distract you from getting to sleep early. Keep your house organized and put all your needed things in their proper places. This way, you will be able to find them again.

You can also use some visual reminders like post it notes on your desk or fridge and use some apps to help you.

Develop a routine

A routine can establish things that you need to do. Of course it’s good to get out from time to time, but just make sure that you are on track with everything you need to do.

Your routine may include things you need to do before leaving the house. In the office or in your workplace, you can try to list down the things you need to do or things you do in a pattern for the whole week. Schedules can help.

Weed out negative people

Negative people may cause you to absorb their feelings. When the people that surround you start to give out negative vibes, avoid them or tell them right out how you’re feeling about the situation. Choose to be with people who keep you positive and who boost your confidence. Negativities can sometimes feed on your positive thoughts, causing problems and taking up a big chunk of your consciousness and focus.


Brain fog can affect everybody. It can hit at the most unlikely times, but many things that can be done to avoid it and to remedy it. If it does happen to you, don’t set it aside as unimportant. Remember, everything starts as a simple first step. For now, try these remedies, they won’t hurt.

Note: Some of the mentioned tips above may not be appropriate for you as they may affect existing treatments or conditions. Your doctor’s advice is still the best thing to seek in conditions like this.
