There has been some research that suggests that Cannabis use may decrease blood flow to the hippocampus, an area of the brain that is important for memory. Yet, what is funny is that researchers are also looking at a possible positive effect Cannabis may have on Alzheimer's...go figure!

The following poll is just an informal one.

Here's my experience. Every drug affects memory.

When I was prescribed benzos, and started taking them during the day, I experienced not only memory lapses, but cognitive impairment too. After about a month, I adjusted and functioned reasonably well. That said, when the benzo would kick in, I would be a bit off, but that would pass. To stop taking benzo's, I weaned off slowly over 18 months. Again, there were memory lapses and cognitive impairment, but that is what happens when a person doesn't sleep.

Now, almost 6 years after benzos, I started using a lot more cannabis to deal with anxiety. When I started using cannabis, there memory lapses and cognitive impairment, but I adjusted. As humans we adapt and, if we are reasonably healthy, we always trend back towards our normal.

If I'm vaping heavily, there will definitely be memory lapses and cognitive impairment, but that is to be expected. The effects seem to pass within 45-60 minutes, and within 90 minutes, I feel nothing.

As for memory loss, is it cannabis or just getting old? Twenty years ago, I could remember IP addresses, and numbers. The math to calculate subnets for CIDR has always confused me, so I just memorized everything. Even today when it comes time for certification exams, I cram for a few days, memorize a lot of information, and then it all evaporates a few days later. It is not completely forgotten; I just use Google to remember things for me.

Stress affects my memory and it impacts cognitive functions. Often, I find I need to take a deep breath, pause, focus on what I am doing, and then complete my task. I'm not talking simple tasks, rather problem solving, or technology related tasks. Is this caused by years of benzos, or cannabis, or just growing older, I don't know.

Have you heard about the boom on Mizar 5?
My memory has always been the same...I think, I can't really remember :ko:

Seriously though when I'm real stoned it's more short term memory that's lost vs anything long term. I can tell you all about something I read on the back of a shampoo bottle 3 years ago but can't remember what I came into this damn room for :hmm:

When I worked in addiction medicine, the most difficult drug to get patients off of were benzos. One of the reasons anesthesiologists were sued was because patients remembered the surgical experience...which is why benzos are given intraoperatively...as amnesties!

I know what you mean about age and computer stuff. I am pretty it literate but these days I find I have to relearn things I once knew.

Remembering IP addresses, numbers, commands to configure a router. That is stuff that always used to stick in my mind. Now, it is still in my brain somewhere, it is just harder to find. I use Google, I see what I need to know, and then I remember. It is like the index to my database needs maintenance.

I know exactly what you are talking about. Lol. I build my own PCs, networks, etc. Picked up a QNas last year, stuck 4 drives in it but have not configured it yet. I am just not as fascile with it.

I have a suspicion that Cannabis may be harmful to some people. Both my parents had dementias in their latter lives which makes me nervous... better get some Viagra.... apparently, it may prevent Alzheimer's...go figure!

What I do, and it helps, is add lion's mane mushroom powder to my breakfast. it's an excellent supplement for improving cognition and other health benefits as well. I add about a half teaspoon to my oatmeal, etc,. and it takes a little time, but after about one month I not only noticed a difference but friends were suddenly amazed at little things I remember. It's ideal for mitigating cannabis memory issues.

Have you tried fish oil?

Years ago, I had a doctor present his argument that fish oils were essential for brain development, mental health, and that SSRI's work better when taken with fish oil. I've pretty much taken fish oil every day for the past 10 years. I cannot say with certainty that it helps, but it hasn't had any ill effects. Actually, bad taste is an ill effect; some brands of fish oil are just nasty.

Your brain is like a filing cabinet.
When you were young you had one drawer to search.
As you get older stuff gets harder and harder to find.

And I've yet to see a 56 year old data base. After 56 years, the indexes must have some corruption.

I'm more of a network security person. The data geeks can look after the data bases.

Yes, we use fish oil daily along with vitamins. I think i also have VAS for vitamins.:)

Into my 40's now and my short term memory seems worse but not drastically so. These days I use CBD, and CBG to offest some of the negative effects of high THC consumption.

I've been doing regular intense cardio for 12 years and I often feel refreshed mentally as well as physically after having sweat things out. I've also heard it said that cannabis impairs your will to remember rather than your capacity to do so....

Recently I've read that exercise produces more of the types of fat that maintain brain health.

I've also read that exercise helps preserve the length of telomeres.

Wait, what was the question? 😅

I dont think cannabis has impaired my memory, but I think my concentration is a little impaired when I'm under it's influence, or to put it another way my ability to not care about things is enhanced when I'm under it's influence.
I will post a number of research articles on the subject that I found.
Thats very good of you I shall read with interest 🙏

That Cannabis may impair concentration and short-term memory acutely has already been established. The big question is with respect to long-term use when not under the influence.

Human memory is way less reliable than people think, even among totally sober people. Also, even under "drug free" circumstances, brains get a little less functional every year after you reach adulthood. My parents don't drink or do drugs. Never have. I've seen with my own two eyes that they are absolutely dumber and have worse memories now, in their 60's, than when I was younger.

My brain is absolutely a little worse now than when I started consuming cannabis in my late 20's. But I'm sure almost all of that is because now I'm in my late 30's. Personally, I'm pretty amazed with how well it still works. It wasn't "designed" to last much past 30.

The poll is over now. I am not surprised by the results although I do wish more people had taken it. We have a guest from overseas leaving tomorrow in the next few days I am going to attach some links and articles on the subject as well as some of my own experience, thoughts, and concerns. Thank you to those who participated.

I have reviewed a lot of studies on the subject and interestingly, the following review was just published recently.


I think it is an excellent review. It pulls from studies that go back many years.

Unfortunately, I think much of it is true. My initial experiences ended in 1969 at the age of 17 so I really can't draw from that time. But, my medicinal use began just this past late September. I have concerns about it's effect upon my own cognition which is in part the reason I asked this question.

As a consequence, I am trying some special strains with low THC content, eg., AC/DC and Pain Killer XL.

One of the issues is the fact that the compound is so highly lipid soluble that it persists in the body for quite awhile. To see how one feels sans Cannabis if one has been using even just about once a night as I have, it takes about a month to clear it as well as all the metabolites. (The reason that those who get urine tested have issues is because the tests don't look directly for THC but rather a metabolite which is actually not psychoactive, 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid.)

There are obviously a lot of variables to consider and one of them that I have not really found anything on is a family history of dementia.

Does having a parent with dementia of any etiology put one at greater risk of developing one if Cannabis is added to the genetic predisposition?

With the numbers of individuals using medical cannabis alone increasing, I think it will be easier to study and find answers to these questions.

I used to kid with people that if there was a quote I wanted to be remembered for it is this:

If a drug is efficacious for it's intended indication, it will have serious side effects and/or toxicity.

If a drug has no serious side effects and/or toxicities, it doesn't do squat for it's intended indication.

Ergo. Any medication that is effective is going to screw you up in some way!

Is this really true? Well, let's just say there is some truth in it and leave it at that. :-)

I am sure everyone has their own experiences and drew their own conclusions on medications.

Cannabis works by supplementing your ECS which strives to maintain balance, in your memory too.
It has been shown to help for those that remember too much (PTSD ) and for those that remember too little (dementia).
Dementia study with lab mice (they have an ECS) where cannabis stopped the worsening and actually restored their memory to juvenile mouse levels.

It’s a complicated affair has healthy memory involves remembering AND deleting memories.

Speaking of lab mice, I just signed up for a federally funded study on cannabis use and memory/ learning/ cognition involving MRI study of the issue.
…..here is your brain on drugs…. 🍳
Remember that propaganda ad???

IMO cannabis probably hurts short term memory but helps with creativity.

Seriously though no, I have not noticed long term negative effects.

Or let's not, and let's look a little harder. If something is true, it should reveal itself. After all Marijuana use has a long history. Maybe longer than most other, if not all drugs.

I don't put any faith in this study of studies. A lot, if not most, previous studies were designed to prove a preconception that Marijuana is bad, and paid for from groups opposed to its use.
Lumping crap together is just more crap.

I think you are a bit cavalier to make ad hoc critical remarks about a review article without any specific reasons. I did not present this as Gospel. Medical information is constantly evolving. The studies reviewed did not pull their findings out of thin air. I offered the link to the article simply for people to look at and review for themselves. I am not suggesting that I agree with every point made.

Memory is a very complex phenomenon involving several anatomical parts of the brain and multiple pathways. Many factors affect it.

In 35 plus years of medical practice I have yet to see any medical therapeutic that does not have some potential side effect. As an example, I distinctly remember the first time I prescribed Prozac for a patent. After just a couple of days she called me complaining of fatigue. We discussed it and she wanted to wait it out. This was before post marketing data had become available. By the end of the week, she could not get out of bed! Obviously, it had to be discontinued. Years later there were reports that antidepressants could make symptoms worse even leading to suicidal ideation.

Everything in medicine is based upon a risk/benefit assessment.

Does Cannabis pose any risks? I think the jury is out. That said, it would not surprise me that over time, certain populations may prove to be suspectable to some untoward effect. The fact that it is a natural occuring plant based agent or that it has been used for centuries does not make it exempt from potentially being harmful. Curare is a natural agent and it will kill you.

Finally, even if it was found to have potential harmful side effects for anybody, I am not suggesting that we go back in time and prohibit its use. Again, it is about risk benefit.

I have discussed this issue with oncologists I know who see more cancer patients than I have. All of them have no problem with Cannabis use for cancer patients.

However, all of them have told me, as have some of my own patients have, that for whatever reason, they don't like the way it makes them feel so they cease using it. Some patients report that they feel their memory is impaired even weeks after use.

None of this is some kind of condemnation. I was not the producer of Reefer Madness. I am just suggesting that it is important for people people making a decision as to whether or not they go down this path that at least do so with open eyes.

This is no different than the treatment of chronic pain. In Europe, if you wanted an Rx for Percocet...forget it. They just never prescribe narcotics on an outpatient basis. Never. It is just not done.

15 to 20 percent of opioid naive patients will be suspectable to addiction. At present, there are no markers to predict suseptability. As a consequence, it is very important to get informed consent prior to prescribing narcotics. Furthermore, a substance does not even need to cause pharmacological adaptation to result in addiction.

So, these are complicated issues.

What may be safe for one person may not be for another.

After 8000 years of anidotal evidence, and countless studies designed to find something to justify reefer madness, I think we'd know if Marijuana has any significant negative effects by now.

I can't think of a better risk/benefit drug, or a drug with a better safety record.
