Memory Loss? Not really. |

One of the most common attacks against Marijuana these days is that weed "kills your memory". The degree of memory loss depends on who you're talking to, but ranges from "only mild short term memory loss" to "life long memory damage". The truth? Life long damage is a crock of shit, and the short term memory loss depends on the type of weed you smoke.
All of the previous studies on MMJ in labs in the USA were using low quality government provided MMJ or solely THC extracted from the plants. It is found that THC does mess with your short term memory, making it harder to remember things that are learned while high, though it's not very severe and it is still possible to learn new information while high and then remember it later while sober. But another ingredient in MMJ called CBD actually counteracts THC and totally eliminates any memory impairment.
Finally a study actually used a realistic setting to test the affects of MMJ, having people smoke their own supply in their house before undergoing testing. The results have researchers thinking that CBD might be a cure or treatment for people suffering from memory related diseases like Alzheimers.
Check out the full article here.
| The findings suggest that an ingredient more plentiful in some types of marijuana than in others may help to reduce the memory loss that some users suffer.
The key difference between the types of cannabis is the ratio of two chemicals found in all strains. Tetrahydrocannabinol (THC) is the primary active ingredient, and is responsible for the effects associated with the classic 'high', including euphoria and giddiness but also anxiety and paranoia. The second chemical, cannabidiol, has more calming effects, and brain-imaging studies have shown that it can block the psychosis-inducing effects of THC2. Skunk-type strains of cannabis contain a higher ratio of THC to cannabidiol than do hashish or herbal types. |
+ Show Spoiler + [How the study was done]
To test this hypothesis, Curran and her colleagues travelled to the homes of 134 volunteers, where the subjects got high on their own supply before completing a battery of psychological tests designed to measure anxiety, memory recall and other factors such as verbal fluency when both sober and stoned. The researchers then took a portion of the stash back to their laboratory to test how much THC and cannabidiol it contained.
The subjects were divided into groups of high (samples containing more than 0.75% cannabidiol) and low (less than 0.14%) cannabidiol exposure, and the data were filtered so that their THC levels were constant. Analysis showed that participants who had smoked cannabis low in cannabidiol were significantly worse at recalling text than they were when not intoxicated. Those who smoked cannabis high in cannabidiol showed no such impairment.

The results suggest that cannabidiol can mitigate THC's interference with memory formation. This is the first study in human to show such effects. One previous study, led by Aaron Ilan, a cognitive neuroscientist at the San Francisco Brain Research Institute in California, failed to find variations in cognitive effects with varying concentrations of cannabidiol3.
Ilan attributes the positive finding of Curran and her team to their more powerful methodology in analysing subjects' own smoking preferences. In the United States, government policy dictates that only marijuana provided by the National Institute on Drug Abuse can be used for research β and it "is notorious for being low in THC and of poor quality", says Ilan.
Lester Grinspoon, professor emeritus of psychiatry at Harvard Medical School in Boston, Massachussetts, who has studied the effects of marijuana on patients since 1967, says that Curran's study is important. "Cannabis with high cannabidiol levels will make a more appealing option for anti-pain, anti-anxiety and anti-spasm treatments, because they can be delivered without causing disconcerting euphoria," he says.

can I ask why you are obsessed with marijuana? I'm NOT saying that your crazy or arguing with your views, it's just that most of your blog posts are about the subject. Are you just doing some research for fun or a project? |

I guess it's the same as with poker players posting here every single article about gambling laws and discussing the matter of poker legalization every day.
Guy likes marijuana and fights for his rights, giving strong evidence against the government. Same shit as poker, just a different subject. |

I was smoking a lot, being very, very stoned most part of the day for about 3 months. After i stopped smoking I felt as if my brain was working at 90% or so of it's "normal capacity" for 2-3 weeks after.
idk if that actually was the case or if i just felt like it was. |

Everyone has different reactions and different strains have different levels of cannabanoids. The thing is that the government has worked hard to block research into Marijuana for the last 75 years so we don't know as much as we should. We know that the brain has cannaboid receptors (ie you brain is built to process marijuana) and that different cannaboids activate different receptors. THC is a cannaboid and it's the main one that gets you "high". There are certain parts of the brain that react to THC. But there are 59 other cannaboids in MMJ that all do different things. If you smoke weed with high THC and low levels of other cannaboids, you'll feel more fucked up etc.
When you have too much of a cannaboid the cannaboid receptors shut down (which is why you can never overdose on MMJ - if you start to have too much it just stops using it). This is how we build tolerance. Usually the receptors that shut down are the ones that impair you the most, ie ones in your cerebellum which impair motor movement will shut down and stop receiving cannaboids. This means that if you smoke on a daily basis you start to get less fucked up but a cleaner high, because you no longer lose motor skills.
Once you stop smoking it takes some time for the receptors to open back up again. So for a bit you might not feel at 100% capacity as that adjustment goes on. But once they open back up again, if you smoke you'll get more fucked up than you were getting while smoking every day. This is why you get more high when you haven't smoked in a long time. |

Of course you can =)
I just restarted college and am majoring in Psychology. In class they went over the ways drugs affect the brain but didn't mention MMJ, so I decided to look it up myself. That lead me into a whirlwind of research which has kind of consumed me. It's interesting to me on many levels, but most importantly I feel as if I've been lied to and fooled for the last 25 years and that has motivated me to learn the facts and then share the information with everyone I can. I'm still far from being an authority on the issue, but I have a lot more info than the avg person does. I say this cause I used to think I was above average in my pot knowledge and now realize I had no clue.
When you examine the history behind why pot is prohibited, the science of how pot actually affects us, and the way pot has been used for thousands of years, it becomes blatantly obvious that a plant that was used religiously and socially with no ill effects for millenia was demonized by alcohol prohibitionists who needed a way to scare people into supporting their federal drug policies. They told us MMJ was bad for us, which is a lie. More than that, there are many situations where it is GOOD for us. And I personally believe that any mature, disciplined adult would actually benefit from regular use, especially by replacing their alcohol use with MMJ use.
I do plan to write a paper on this by the end of the semester and probably more papers throughout the rest of my college career. That's why I've started blogging about it - to help myself practice a bit and get the knowledge better ingrained in my head. Plus I get to spread some facts and truth and liberate people from the lies that held me down for so long. |

people who smoke every day are effectively trying to forget everything about those days imo |

It depends. If you're basing that statement off of a study it's probably because the study used THC only. Instead of having someone smoke marijuana, they take 1 of the 60 cannabinoids and give you that. THC is the cannabinoid that gives you the most "wasted" effects - difficulty in short term memory recall, loss of coordination, and psychedelic effects in high enough doses. Some strains have more THC than others, and some strains have more THC than other cannabinoids.
Lots of THC and no CBD will make you more fucked up. CBD provides a few of the more medical benefits of pot like helping with memory, helping you sleep, etc.
Also there's a difference between occasional and habitual users because of the way tolerance develops in the brain for MMJ. If you only smoke once every week or two, then you will get much higher those few times you smoke than someone who smokes every day. This happens because the cannabinoid receptors in your brain stop taking in cannabinoids, like THC, when they feel like there's been enough administered. Like a biological bartender cutting you off. Once the THC goes down in the system the receptors start to open back up slowly. The thing is, the receptors that shut down are often ones that cause some of the ill effects of MMJ like motor functioning, short term memory recall, and a few more. So what happens in the end is if you smoke consistently you get a "cleaner" high, while if you smoke occasionally you get a more "drunk" high where it's harder to function. |

Have you ever smoked every day for a sustained period? I know many highly functional happy people who smoke every day, including myself and my wife. I have actually had a lot of positive life effects from smoking weed because I have the basic discipline to be smart about it. I don't smoke if I have any intellectual work to do - like going to school, doing homework, going to a job, etc. I usually smoke in the evenings after I've done everything I need to do for the day, or during the day on weekends when I don't have anything big to do. Mindless labor is much better after smoking though, so washing the dishes, watering the plants, cleaning the yard, vacuuming the house, etc, are all things I will do after smoking and the worst thing that happens is I do the work slower but more thoroughly.
I used to think that smoking weed was ok, but only if you did it on occasion. When I first started to smoke more than 1 time a week I felt guilty about it, and a bit worried. But I had friends who smoked every day and were some of the happiest, productive, and healthy people I knew so I figured it couldn't be horrible and went for it. Now that I've got my medical card and can pick several strains, I find that smoking every day is great. You choose the strain for the occasion, avoid the weed that will couch lock you or get you super high at times when it's not appropriate, and party hard when the time is right. And now that I've got a bong and am away from the harsh smoke of a pipe or joint, I plan to keep smoking every day. There have been case studies showing that long term use of MMJ causes no physical damage, cognitively or physically. There are no studies showing long term negative affects of MMJ. So I plan to keep smoking every day and enjoying my life as much as I am right now. And I don't want to forget any of it. |

i made a million dollars smoking weed regularly.
then i quit after i made over a mill cause it was boring.
maybe that will help your studies k2o4 |
