High Free Marijuana?

There is marijuana that does not get people high.

As I have mentioned in the past, there seems to be a conflict between marijuana that has medicinal properties and marijuana that gets you high.

Marijuana that is more medicinal is believed to be high in a chemical called CBD. CBD does not result in intoxication.

Marijuana that gets you high contains large amounts of THC.

Till now if you smoked medical marijuana you were going to get high and frankly that is what most medical marijuana users want. That may be changing.

Just saw a piece on MSN about an Israeli company that is growing a high CBD variety of marijuana that has medicinal properties but does not get you high.  MSN included a link to the BBC original article that can be found at http://www.bbc.co.uk/news/world-middle-east-20189347

Let me know what you think about this.

How does Marijuana affect memory?

Does Marijuana use result in State Dependent Learning?

In a previous post, I wrote about the concept of State Dependent Learning (SDL), how things learned while you have a drug in your bloodstream may be better remembered when you have that same drug in your body. Readers have asked if Marijuana use results in SDL and what other effects does marijuana have on memory?

If Marijuana causes state Dependent Learning then we should advise people who learn things while smoking Weed to also smoke weed while or shortly before needing to use that information.

Will smoking marijuana just before a test help students who smoke while studying remember the facts better for the test?

Clearly, a great many things, mood states, drugs in the system, even the general health of the individual can affect memory. Unbiased information about the precise effects of Marijuana on memory and learning has been difficult to find.

There are a number of reasons for the contradictory reports of health benefits and harms of Marijuana we read in the media. I have been reading the research since my last post on SDL and here are some of the things that I have found.

Marijuana is more like a stew than a vegetable.

Marijuana contains over 600 chemicals including 60 to 70 Cannabinoids (another article listed 116). Two of the Cannabinoids have some research data but a lot of the other chemicals are poorly understood and have little research. All of the possible combinations of these 600 chemicals create unlimited possibilities for effects. That is not the only reason we know so very little about the effects of marijuana on memory.

How does it work?

For a long time, we knew that marijuana was doing something, we just could not find any receptors for the Cannabinoids in the nervous system so we did not know exactly what Marijuana was doing to the nervous system. Starting in the late 1980s and the early 1990’s receptors for Cannabinoids were found. But there are multiple kinds of receptors and they are located in some parts of the body and not others.

Many of the nerve cells that make up our “brain” are not in the head. When you are hungry the nerve cells in your stomach tell your brain that the stomach wants food. The same thing happens with Cannabinoids. Many of the Cannabinoid receptors are located in places like the spleen and the tonsils. So marijuana might affect memory for pain in the throat differently than memory for the history test.

Worse yet as we study the various Cannabinoids they don’t all do the same things. The two most widely studied Cannabinoids delta-9-tetrahydrocannabinol (THC) and Cannabidiol (CBD) appear to do opposite things. THC seems to produce thinking distortions. The younger you start using THC the more likely you are to develop psychosis. CBD, however, has been proposed and tested as a treatment for psychosis.

One theory, on this contradiction, postulates that young marijuana plants have more CBD and less THC. As the plants mature they form more THC and the CBD is reduced. So if there is high THC, which is the Cannabinoid that gets you high, then it has low medicinal properties. Plants with lots of CBD and that might be more medicinal don’t get you high. But most medical marijuana users want the kind that gets them high. What the other Cannabinoids are doing we are not really sure.

It depends on who makes the stew and how long you cook it.

One other problem with the research on Marijuana is that the concentrations of all the chemicals change depending on how the Marijuana is grown and how it is processed or dried after harvest. Various studies on Marijuana may really be studies of all sort of different chemicals, not just the Cannabinoid.

Recent research has tackled this problem by using pure synthetic Cannabinoids so when testing THC or CBD that is the only chemical being tested.

There are different types of memory and memory operations.

Short-term memory is info that is held in memory for a minute or less. Drugs, emotions even attention can interfere with the ability to take in information. Ever read something in a book and a second later realize you don’t remember what you read? This is a failure to encode information into short-term memory.

Marijuana, particularly THC, has been implicated in the failure to encode the information.

Working memory is information being processed. Some information can be distorted while in processing by the drugs in the system. Alcohol especially can make the drunken person think things are happening that in fact did not happen.

I have not found studies that suggest that marijuana (THC) is altering information processing but it is altering some other memory events.

Long-term memory is information held in storage.

Inability to find, access and retrieve information is what State Dependent Learning is all about. With SDL it is easier to retrieve previously stored information when the drug that was present during storage is again present.

Marijuana use has not been shown to affect memories formed prior to the use of Marijuana. It is not likely to help reduce PTSD symptoms or unpleasant memories of the past for more than a short time period.

So far no studies I have found indicate that THC improves the ability to locate material that was previously stored.

Retrieval is the ability to find and pull up information.

If the information that you retrieve is inaccurate or incomplete this is a retrieval error.

THC appears to reduce the encoding of information so less gets into short-term memory and less is stored away.

THC is also reported to interfere with retrieval of information.

Smoking marijuana while studying results in learning less. Smoking marijuana just before taking the test interferes with remembering what was learned.

Marijuana use (THC) does not create State Dependent Learning and further use will not help recover memories of information learned while under the influence of marijuana.

There are plenty of people who smoke a lot of Marijuana and remember things just fine and there are people who do not smoke weed and have a poor memory, clearly smoking or not is not the whole answer.  But smoking weed has not been shown to improve memory or help retrieve previously learned information. It has been shown to interfere with encoding and decoding of information.

Under the influence of THC, you will learn and remember less than you would without the weed.

Stoned driving

Stoned Driving on Marijuana.

You are more likely to be involved in a fatal car crash if you drive while under the influence of marijuana. Being stoned behind the wheel increases the risk of an accident even when there is no alcohol present in the driver’s system. We found this out not with one small study but with nine studies which together included over 50,000 people.

Driving under the influence of marijuana about doubled the risk that you will be involved in a motor vehicle crash. This analysis didn’t come from the DEA or a “law and order group” but is from a study recently published in the British Medical Journal.

This isn’t the first time studies have shown this result. In a 2009 report from the National Highway Traffic Safety Administration, they reported that almost ten percent of drivers were under the influence of marijuana. They also concluded that over sixteen percent of drivers had drugs of all kinds in their system. Till now it has been easy to doubt that it was the Marijuana that was causing the impairment because older studies did not separate out people who were impaired by other and by multiple drugs. The British study solved that problem by looking at the risks of people under the influence of marijuana only, as opposed to those who were not impaired by any drug at all.

Why did they find that marijuana impaired a person’s ability to drive? We know that alcohol impairment is a serious problem. Alcohol interferes with driver’s awareness of speed and it reduces their reaction time. I tell students that a simple way of understanding alcohol Impairment is that alcohol shuts down the part of the brain that tells us “Hey stupid don’t do that.” What does the marijuana do?

Marijuana alters people’s perceptions of space and time. Marijuana affects “special location.”  Stoned drivers follow too close, misjudge how close they are to the car in the other lane and tend to swerve in and out of traffic often cutting the distance too close. Additionally, drunk drivers tend to know they are impaired and they often slow down. Sometimes they slow down way too much. Stoned drivers don’t do that. They can’t tell how fast they are going or how far away they are and they don’t feel that impaired.

The problem of stoned drivers is not a small thing. We have begun to recognize just how often serious automobile accidents are the result of impaired drivers. Just because a drug is prescribed does not make it safe. People are getting arrested for driving under the influence even when they have prescriptions for the drug. The fact that some people have prescriptions for Medical Marijuana, has lulled many into a false sense that this drug has no downside and is safe.

I continue to have conflicts about the use of Medical Marijuana. There are those who swear by it and report great medicinal befits. I am all for reducing human suffering and increasing happiness. But the idea that you medicine might kill me or someone I love makes me skeptical. I think people on both sides of the Medical Marijuana debate have left out things that we should know. I plan to write more on this in the future. But for now, I would conclude that if you need to use Medical Marijuana please don’t drive.

Till Next time, hope your life is happy, David Joel Miller, LMFT, LPCC.
