Responses to Brain Fog and Marijuana Withdrawal Questionnaire

By October 7, 2021October 23rd, 2021No Comments

After you quit weed, or perhaps while you’re still using, you may experience a lack of focus and mental clarity commonly referred to as brain fog. You may have difficulty concentrating or you may notice a worrying drop in productivity.

As with other withdrawal symptoms, the cognitive difficulties you encounter will be unique to you, and represent your brain recalibrating after an extended period marijuana use. Take comfort in knowing that you are not alone. Today, we’re bringing you accounts of 270 people who have recently quit using marijuana. Responses were gathered from an anonymous brain fog questionnaire posted on Weedless.org.

How much of your day is impacted by brain fog?

Are any daily activities disrupted by your brain fog?

When is your brain fog most severe?

Have you experienced any difficulty falling or staying asleep?

My speech also becomes kinda slurred, verbal memory is terrible, cant structure the whole speaking pattern and using the correct norms, words even terminologies that are part of my profession.

First of all, I’m a very light smoker. One to two hit a day at most. Note regularly three to four hits a week. Either of those scenarios will put me in a fog by the third day which will cause me to stop. First symptom is congestion. I think maybe some is trapped in my nasal passage. Then comes the fog, can’t remember words, poor concentration, comprehension. When reading my Renton is terrible. Can’t do anything mentally challenging. My vocabulary goes from college level to third grade  with a lot of mum’s and “What’s the word I’m looking for.”

  • Habit: One to two hits from a joint, pipe or bong each day

So that all started in about 2000 when a whole bunch of other allergy symptoms hit and other health effects from the exposures. My tolerance for a lot of things went down and I became sensitive. Couldn’t wrap my head around any of what was happening at the time.

Intense brain fog, forgetfulness, difficulties with short term memory, staying focused, speaking,   I’ve NEVER had social anxiety before but, for some reason I’ve been getting really anxious in social settings. I freeze up and don’t know what to say. Even around people I know.  I will feel confused and not quite able to understand things after I’ve read them or even during conversation with others, which is embarrassing and upsetting.  I have trouble articulating my thoughts accurately, as well; something I’ve never dealt with, which can be extremely frustrating. I stumble over my words or have trouble speaking.
