How to deal with marijuana brain fog is a commonly asked question online. Even with all the benefits that marijuana has, if you consume too much, it can give you marijuana brain fogginess, and that experience can possibly turn you off from cannabis altogether. But tell me how to deal with marijuana brain fogginess?

Many people who have been smoking weed for a long time still have issues with marijuana brain fog, and it has largely to do with the frequency and amount of weed that they consume. Also the THC content and potency of the cannabis they use.

Marijuana brain fog can occur after you have consumed weed and is characterized by this clouded and groggy feeling that can make you feel drowsy and unfocused. You may feel like your head is in the sky.

This feeling can feel impossible to shake, but goes away after a period of time. A little sleep could do the trick, depending on the level of consumption. But, even with that, you may be in a social situation where clarity is essential. What do you do then?

The mental fog can turn out to be a negative outcome, if you don't know how to manage it. Marijuana brain fog usually feels as if you are a second behind everyone else.

In other words, you feel a bit slow about what is going on around you and your short attention span can rival that of a goldfish. However, there is good news. It is only temporary and won't last forever.

While it can be annoying or embarrassing when it happens, there are ways to avoid the fog. We have compiled several things you can do to stay mentally sharp. Let's dive in and learn how to get rid of a weed hangover and deal with greening out.

What Is Brain Fog?

Brain fog refers to a set of symptoms that can impair your ability to think. And, it's not just marijuana that can cause this mental state. In this state, you may feel confused, disorganized, and unfocused. It can be hard to form your thoughts or even speak.

Common causes of brain fog also include:

Any of these causes can make marijuana brain fog more likely. If you suspect your brain fog is caused by any of the causes listed above, consult with your doctor to determine a proper treatment program.

Do not immediately assume that your brain fog is due to cannabis consumption. There can be other factors at play. However, if you're fairly certain that your brain fog only comes after consuming cannabis, there are ways to relieve this and improve your mental clarity.

Cannabis can cause brain fog due to the THC content. Higher THC cannabis is more likely to cause brain fog.

Cannabis consumption can leave users feeling mentally and physically slower, although they may also experience its therapeutic benefits, too. Brain fog can last well beyond the moment of consumption.

Some users can experience a mild form of fogginess for a day or several days after consuming cannabis. This is especially common in heavy, frequent users, since THC can be stored in the fat cells and be gradually released back into the bloodstream.

While cannabis research is still in its infancy, most studies have found that cannabis causes cognitive decline, especially with long-term usage.

Cannabis abuse can come with higher cognitive decline compared to non abusers. Knowing how to consume cannabis in moderation is one of the best ways to avoid its negative cognitive effects.

What are some brain fog treatment steps?

Drink more water, take a walk, take a nap, and get adequate vitamins.

The Beverages For Brain Fog

When you feel as if you have a marijuana brain fog, it is best to reach for something to drink (except for alcohol). It could be juice, soda, water, or coffee. But, why would you want to do that? Well, increasing your blood sugar is an excellent way to boost your attentiveness.

The beverages help to surge your energy and make you feel more invigorated. Light snacks are also good to add. If you are a coffee lover, get a hot cup of java or make some iced tea if the day is very hot. This could put you in an upbeat mood.

However, try not to drink too much because it could make you feel jittery because of the caffeine, and who wants to be jittery and groggy; all at the same time?

Pro tip: If you suffer from chronic inflammation, avoid consuming sugary drinks. Refined sugar can increase the risk of chronic inflammation.

CBD Inhalation For Brain Fog

One other way to deal with marijuana brain fog is to use a vaporizer with high levels of cannabidiol (CBD) strains. This is one of the most efficient and fastest ways to lower the feelings caused by a marijuana brain fog.

It can take only five minutes to reduce those feelings. CBD is believed to have calming effects, even in small doses, so it can aid you in reducing social stress caused by brain fog.

CBD can give you a sense of wakefulness and energize you. It can clear the fog, so to speak. More importantly, it can have a synergistic impact with tetrahydrocannabinol (THC) in a strain, extract, or infused product, which subsequently helps to reduce any feelings of drowsiness and confusion.

Pro tip: Don't have a CBD vape on hand? No problem. A CBD tincture or edible can work. Edibles and tinctures can take a couple hours to kick in. Sublingual administration (under the tongue) of a CBD tincture can take effect within 15 minutes.

Drink Water

Water also helps to center your body and provides hydration. When you drink water during a marijuana brain fog, it can make a whole lot of difference to how you feel. Even mild dehydration can impair cognitive function, so you want to keep water handy at all times.

Smoking weed reduces the secretion of saliva in your mouth producing dry mouth, also known as cottonmouth. Drinking water gives the reverse reaction. It also increases your cognitive functions at a time when you need it most. When you drink water, it gives you back your mental clarity and helps with brain health.

Take a Walk

Consider taking a walk to get oxygen back into your brain, so you don't feel so sluggish. Brain cells are very sensitive to a lack of oxygen and can die off if they are deprived of it for long. Fresh air filling up your lungs outside is one way to begin.

It can be hard to feel motivated to take a walk, especially if you consume a couch-locking strain such as an indica, a strain with high levels of cannabinol (CBN), and sleep-inducing terpenes such as myrcene, beta-caryophyllene, and linalool.

Pro tip: Can't take a walk around your neighborhood for whatever reason? That's okay. You can increase your brain’s oxygen levels with a few deep breathing exercises.

Take a Nap

You could also take a nap, if that is possible. Getting enough sleep is very important for brain health. Find a comfortable spot on your couch or bed to lay down, close your eyes, and focus on your breathing. Mental fatigue can occur when you do not get enough sleep. Try to find a quiet place, so you can get a nap in and feel rejuvenated afterward. Look for the best strains for night time use when choosing your cannabis. Many strains can help with cognitive impairment, bud function, nervous system issues, cognitive dysfunction, body temperature, and cloudy thinking.

How to Avoid Brain Fog

If you consume cannabis and you feel like it is hindering your ability to think, you don't have to quit cold turkey. There are few ways to reduce or completely avoid the feelings of brain fog after cannabis consumption.

Here are a few tips to keep in mind:

  • Be aware of the dosage you are consuming. Too much can leave you feeling stuck in a fog.
  • If you believe large doses are causing your brain fog, take a short tolerance break and then start off with the lowest dose possible and gradually build up until you find your desired effects with no or minimal brain fog.
  • Experiment with different products. Edibles may be more intense than vapes or flower. In addition, some strains may be more sedating and cause more brain fog than others. Consider the concentration and types of cannabinoids and terpenoids in your product, too.
  • Keep a consumption journal to track how you feel with certain products and strains. Make note of the time of day, dosage amount, consumption method, and other feelings that can help you avoid brain fog in the future.
  • If you want to use cannabis and understand that you can experience some mild delay in your cognitive function, you can time when you choose to experience this. Avoid consuming cannabis before you perform a task that requires focus.
  • Brain fog can be due to a number of lifestyle and genetic factors. Health experts recommend at least 7 to 9 hours of sleep, 30 minutes of physical activity most days of the week, and eating a well-balanced diet full of veggies, whole grains, and fruits. Embracing a holistic lifestyle can help you keep your mind sharp.

Ultimately, brain fog is a fleeting feeling that can occur if you consume too much or the wrong type of cannabis for you. If you do happen to feel like your brain is not as quick as others after consuming cannabis, it does not necessarily mean that cannabis is not right for you. If using cannabis, look for THCV strains for helping reduce stress and anxiety. Strains for anxiety can be helpful and a good way to not rely on medications such as Xanax or other benzos.
