Does Marijuana Cause Permanent Brain Damage in Adults?

A shrunken hippocampus can be a result of trauma. A lot of people who smoke weed were traumatized.

It's not the marijuana's fault. It's more of a "if you don't use it, you'll lose it" kind of thing. When you're high you don't do things conducive to stimulating and exercising the brain. In other words, I bet if they had a control group that did everything the weed smokers did except smoke weed, then their brain performance would go down too, just like the taxi driver in the video.

Basically we don’t know yet.

I smoked from 15 to 21 (2001-2007) and I see at work that I've issues for memorising and concentration. I'm a bit worrying. I gave up long time ago but still. I cannot understand how we have people that are still saying that smoking is not bad for you.

From my personal experience, cannabis has made me more clever and open minded. At the same time its difficult to memorize information

Weak people need drugs to feel better its ok

Why does this dude sounds like he is high?

What if you only smoke it once every few months, would that also cause damage. Also, what about bongs, are they better or worse for your health than joints

I think if you have too much, it will reduce creativity, but when I have an optimal dose, I'm pretty damn sure that the creativity I experience isn't an illusion. I hear awesome pieces of music created on the fly in my head, in an effortless way, something I never get sober, even if I try. It feels like my mind goes with the flow more and will explore new trains of thought it otherwise wouldn't.
edit; I'm interested if these studies controlled for whether or not people were having within the optimal dose range for cannabis. The biphasic dosing effect means high doses worsen symptoms, and I suspect most people don't pay attention to optimally dosing themselves.

Some info on biphasic dosing if you're curious on what it means: https://www.labroots.com/trending/cannabis-sciences/11870/biphasic-effect-cannabinoids-controls-dosing

Though there's also twins studies that don't account for the dosing, but found no noteworthy difference between a cannabis-using twin and non-using twin, with any shared decline instead being explained by family background factors the twin adolescents shared;

the only link i can see between NUTRITION and cannabis is that I'm more likely to eat unhealthy when i'm stoned , sorry not sorry.
-yes im baked , yes Im eating a large pizza with extra chesse.
o shit by the way the link over there is a study from harvard.

Its nice to see on paper what is seen in clinic. Remember, this is not the ultra-low TCH medical use marijuana, this is the High TCH Recreational Use Marijuana. Come on, did you think a toxic substance that can affect cognitive function crossing the blood-brain barrier would not be harmful? Ever wonder where the term 'swiss cheese affect' came from when people talk about the brain of older long-term alcoholics? The THC in Marijuana is no different, Toxic chemicals damage, luckily we can recover if not over done. Some of the 'exploring' that occurred as you were young (I was in highschool in the 70's) as long as it was not a lot should do no harm, but if you kept denying life's lessons into your 20's, then you may see the brain damage, or not…. 😉

Well I’ve been smoking since I was 12 and I still make good grades like all As in elementary and middle school and As and Bs in high school

The point is that it does cause impairment and there is also a spectrum of reactions, people are chronic users, they aren't going to stop for 15 years to repair the structural changes noted. Also, please keep in mind that weed is becoming more and more potent as time goes by and these studies are going to rapidly be less reliable with the new potent strains. Not to mention these studies are very limited in scope. We do have entheogenic use in traditional cultures and in these cases it was not used except in very limited circumstances on a frequent basis. I am afraid that those limited studies outstanding, what we have going on is a widespread cultural delusion of it not having any negative effects at all and a widespread experiment of a great deal of people using it in ways and doses and frequencies that any traditional culture associated with its use would caution heavily against.

Smoking is so yesterday. Vape. Eat Drink.

bla bla bla spark it up!!!

I wonder if this atrophy is connected with a specific component of the plant. Is it connected with THC, or CBD? Or is it related to SMOKING it? Any idea?

it does everything and it will kill yo ass

No

I can think of No Other Drug or substance that the people have had to force the government's hand. The government is here because the people created it and gave it enumerated powers, outside of those Powers it has none. This is why they needed to pass a constitutional amendment to ban alcohol. It's just more proof that any ban on a substance is unconstitutional and the people pushing it should be arrested for all the damage they've done to society. Furthermore, their property should be used to pay damages to those who have been imprisoned and injured due to the crime created by increased prices for products that should be legal and relatively cheap. It doesn't affect me at all if somebody wants to smoke crack or heroin, but when the police enforce laws that make it more expensive, and it forces people who are addicted to the drug to break laws, that is a problem for me. That means that the law enforcement and the legal system is the problem that is causing the injury. Remove that problem and we will have solved the drug issue. Nobody should be concerned with what other people are doing in their house. If you are concerned with what other people are doing in their house then maybe we should come into your house and make sure that you have everything in order and legal. I mean, what do you have to hide?

I see that you are only making anti-marijuana studies, but there are also studies for marijuana and cancer (glioblastoma etc…) it would also be nice to add a link to the studies in video description (pubmed etc..)

Lol I’ve been smoking since I was 15 everyday all day . I am now 41 . I can safely say it doesn’t do any damage to your brain . I say it comes down to the individual. If the person was a loser before smoking then they’ll be a loser after smoking . . People need to just stop . Alcohol does way more damage to your body and brain . Same with bad food for you . I still don’t understand why herb is so hated and picked apart . But like anything in this world if it’s good or helpful it will be illegal . If it’s bad for you and will end your life faster it is made readily available

Dabs give cancer, fact.
