>According to one of the co-authors on the study Elisabeth Jorandby, M.D., “As a physician who routinely sees marijuana users, what struck me was not only the global reduction in blood flow in the marijuana users brains , but that the hippocampus was the most affected region due to its role in memory and Alzheimer’s disease. Our research has proven that marijuana users have lower cerebral blood flow than non-users. Second, the most predictive region separating these two groups is low blood flow in the hippocampus on concentration brain SPECT imaging. This work suggests that marijuana use has damaging influences in the brain – particularly regions important in memory and learning and known to be affected by Alzheimer’s.”
>According to Daniel Amen, M.D., Founder ofAmen Clinics, “Our research demonstrates that marijuana can have significant negative effects on brain function. The media has given the general impression that marijuana is a safe recreational drug, this research directly challenges that notion. In another newstudyjust released, researchers showed that marijuana use tripled the risk of psychosis. Caution is clearly in order."
At least tobacco improves your memory and staves off Alzheimer's.
Jack Butler
I agree, disregarding the negative effects which are only really a problem if you use it in excess, tobacco is pretty great. You can buy it anywhere, smoke it anywhere, smoke it and drive a car/ be productive/ operate machinery.
Ryan Bell
I think it's common knowledge to not smoke pot when you're still developing. mentally wise that is.
later 20's and over is fine but anything before than makes you retarded

I think we already know marijuana is bad for developing brains. It's the same for alcohol, it fucks up your development if you start drinking early.
It doesn't do anything once your brain has developed fully around 21, when it's legal to consume.
Joseph Turner
ya lazy, son? Too much reefer? Read the link, and the DOI is there too.
It doesn't even finish developing at 21. Try 25 or later.

Grayson Wright
What about studies researching health influence of anal sex?
Leo White
Smoking every now and then doesn't make you dumber and people who believe that are quite retarded. 'smoke everyday/all day people' were retarded before they started smoking.
Alcohol is consumed much more in our societies and it's already proven to give you permanent neurological damage, so worry about that.
Luis Diaz
That is pretty unhealthy too m8
On topic: Smoking. There is no safe way, just the fact that you smoke anything is already a downgrade 4 your healt lads. Just do it with moderation
Christopher Rogers
So marijuana, smoking in general, anal sex, gay sex, and fatties should be banned. There are literally zero logical arguments against that.

Weed smokers are like niggers, most of them are bad and will argue you blue in the face that they are not and that it is YOU who are wrong.
Source: I was the sole non-smoker in a group of stoners. All of them bar one guy are addicted, act retarded on it, have actually become more stupid and get agitated if they can't get smoke - one guy can't sleep without it, another literally couldn't muster the energy to fuck his gf so she wanted to sleep with me complaining that he was useless at sex and had no drive and here's the clincher: he knew about it and DIDINT CARE!
It's not a good thing to smoke all day, it fries your head. In regards to one guy I know who is cool, he smokes once a day or every few days an has one maybe two joints, chills with a cup if tea and watches a movie, he never wastes money in it and it lasts him a long time. THAT is good smoking...it's just rare.

Elijah Bell
Yeah so you can remember how much it fucking sucks to have emphasema and cancer and a fucking hole in your throat. Besides tobacco only increases memory because of an increase of dopamine which can be accomplished in much healthier ways.
William Gonzalez
so you want to ban anal sex and gay sex? by that do you mean you want to ban oral sex?
Jacob Richardson
I smoked every other week like once or twice for about 6 months then I stopped because the novelty wore off. I can't imagine people integrating this in their life style and go full smoke weed everyday.

I smoked some strong weed a couple of weeks ago. Ive always been high anxiety but i had the worst panic attack of my life, thought i was having a heart attack. These panics attacks have continued for 2 weeks straight and its freaking me out, never had it this severely. Needless to say, fuck the green jew.
Cameron Reed
Theres people who smoke every fukin day, post those shtty pics on instagram, and think there hot sht, then wonder why thy ended up like there parents, dont get me wrong nothing wrong with smoking here n there but like u said the novelty wears off pretty quick n it soon vecomes childish, evrything my friends ask me why i dont smoke i just want to respond with "because i make 100k a year withoht a degree, while ur still paying ur debt in a 60k a year job" but whtever
Daniel Smith
Do you get the same benefits from vaping?

I got a friend who needs to smoke everyday or else he is unhappy and grumpy. He smokes Evert 20 minutes compulsively and goes to bed as soon as he runs out. He can't be awake and sober at the same time.
Kind of look forward to seeing how far he goes in life.

so what have we learned eh? pot doesn't make people weak, the weak people make pot look bad: you all act like this is a powerful drug when it isn't in the slightest. you are just using examples of weak characters, no wonder ur all fucking hopeless u say what u see like children
Christian Lee
Well that makes it ever more stupid. Why would you show lack of blood flow by making the brain rougher. Then there is holes in the motor cortex? But it doesn't mention that it effects the motor cortex. Plus why are they making the argument that is effects the hippocampus when they don't even show the hippocampus in this example.
Hudson Sullivan
it seems pretty obvious that being in an altered mental state literally every waking hour would be bad for you, but there's a lot of people that do do that, they just smoke constantly whenever they have a bag. nothing wrong with smoking at the end of the day before bed or whatever, but that's a lot different i feel.

This is likely sensationalist faux research designed to manufacture relevance and credibility for amen clinics. Total garbage otherwise, like their "health" services.
Cameron Stewart
It's a sample picture. The paper has more accompanying photos. They're not showing lack of blood flow by making it rougher, what? They don't need to simulate brain folds to give a general direction of blood flow. A lot of different kinds of scans are like this too. Not just the research project's software's scan.

as long as you keep using your brain you will be fine.
dont smoke weed and play video games smoke weed and learn a new skill
and also dont smoke before 21 while your brain is still developing, preferably you should wait until you're 25.
i started at 20, but meh, lifes been good and i make good money doing what i love.
Jacob Young
I haven't smoked in a month, it wasn't a deliberate choice, I just haven't smoked because I don't have a need to, sometimes I smoke 10 cigarettes a day, sometimes I smoke none, just depends on my mood and how bored I am.
I don't think nicotine addiction is so bad, some people are just very sensitive too it.
I've never vaped, but I've seen on a friends the fluid contains 24mg of nicotine, the cigarettes I smoke have 1.2mg of nicotine per cigarette so the fluid is like a pack, I don't know how you know when to stop smoking it though, with a cigarette you're done when its done, but how do you know when the time is up with a vapo.

I was just going to post this. The guy's a self-help guru. It's called fucking "Amen Clinics." I wouldn't trust this source over the peer-reviewed studies that have shown the brain is not at all permanently affected by use.
Cooper Cooper
I started smoking a bunch when I was 16. I barely scraped through high school despite being an a+ student prior to my habit. Every day use demotivates me and makes me foggy. I still occasionally smoke instead of drinking and it makes life so much better. Keyword: moderation. You don't wake up and drink 4 beers, that's considered unhealthy. So why is wake and baking normalized? Why is it cool to smoke every day? It's not. It's the green Jew. There's a reason no one pushes for that shit except the left.
Gavin Harris
ive smoked for 8 years, i tried to quit 3 times with no success, the 4th time i just cut the crap for good, promised to never return to it. 10-20 cigs a day. You say exactly what my other smoking friends say -ooh i can quit at any time - and when the nicotine addiction kicks in they are back on the hook. Fuck that. Never again!

Alzheimer's disease is the leading cause of dementia among the elderly, and with the ever-increasing size of this population, cases of Alzheimer's disease are expected to triple over the next 50 years. Consequently, the development of treatments that slow or halt the disease progression have become imperative to both improve the quality of life for patients and reduce the health care costs attributable to Alzheimer's disease. Here, we demonstrate that the active component of marijuana, Δ9-tetrahydrocannabinol (THC), competitively inhibits the enzyme acetylcholinesterase (AChE) as well as prevents AChE-induced amyloid β-peptide (Aβ) aggregation, the key pathological marker of Alzheimer's disease. Computational modeling of the THC−AChE interaction revealed that THC binds in the peripheral anionic site of AChE, the critical region involved in amyloidgenesis. Compared to currently approved drugs prescribed for the treatment of Alzheimer's disease, THC is a considerably superior inhibitor of Aβ aggregation, and this study provides a previously unrecognized molecular mechanism through which cannabinoid molecules may directly impact the progression of this debilitating disease. pubs.acs.org/doi/abs/10.1021/mp060066m

Thats bullshit, have been a daily smoker since 15(now 30). Didn't start with hard drugs till i was 22. Went cold turkey on hard drugs on april.
Cannabis is shit though, those claiming it doesn't make you addicted are lying. Try go 1 year without after been smoking everyday for over 2 years..
All drugs are bad if used regular.

In recent years the proclivity of cannabinoids to exert a neuroprotective influence has received substantial interest as a means to mitigate the symptoms of neurodegenerative conditions. In brains obtained from Alzheimer's patients alterations in components of the cannabinoid system have been reported, suggesting that the cannabinoid system either contributes to, or is altered by, the pathophysiology of the disease. Certain cannabinoids can protect neurons from the deleterious effects of β-amyloid and are capable of reducing tau phosphorylation. The propensity of cannabinoids to reduce β-amyloid-evoked oxidative stress and neurodegeneration, whilst stimulating neurotrophin expression neurogenesis, are interesting properties that may be beneficial in the treatment of Alzheimer's disease. Δ9-tetrahydrocannabinol can also inhibit acetylcholinesterase activity and limit amyloidogenesis which may improve cholinergic transmission and delay disease progression. onlinelibrary.wiley.com/doi/10.1038/sj.bjp.0707446/full

>Methodology is in the paper, buddy. It's not un-replicable. Don't be an idiot. Speak for yourself. This thread is an experiment in confirmation bias based on dubious science found in single studies that have not been replicated anywhere else.
The vast majority of research, including research published by this same Alzheimer's journal, show's the exact opposite of this. They also, coincidentally, happen to not disregard whole swathes of study on Alzheimer's having to do with Amyloid Plaques, which cannabinoids have been shown for years to help protect against and prevent.
Some people are very sensitive to nicotine, I've been smoking since I was 15, 10 years ago, I smoke 2-3 packs a week on average, but I've quit many times in the 10 years and the amount I've smoked has varied between 1 and 10 a day.
My friend has very little resistance to nicotine, he doesn't really smoke, I sometimes give him a cigarette when I go smoke, when I give him too many in a week, about 3, he starts getting hooked and keep asking if we can go smoke.
