Here for a good time, not a long time.
Alchoholics have shitloads of problems too. How is this news?
Smoke twice a week at most and you'll be fine.
ffs
this article doesn't detail whether or not the researchers considered the impact permanent.
I haven't smoked for years but did heavily during my teenage years and early adulthood.

Yeah, but how much daily consumption are we talking here? Why are journalists of all stripes so inept at reporting on science accurately in layman's terms?
Sounds like a chicken or egg debate to me. Maybe they like to smoke pot because they have poor blood flow in the brain.
Binge drinkers and alcoholics with multiple detoxifications have impairments in executive control tasks sensitive to dysfunction of prefrontal cortex. Animal studies show that repeated withdrawals are associated with an inability to learn new information. The mechanims of neurotoxicity and kindling of neurotransmission systems is due to alcohol's acute effects on GABAergic enhancement and NMDA suppression, leading to CNS depression leading to a partial acute tolerance to these effects, followed by a rebound effect, during acute withdrawal due to the partial tolerance that developed. The acute withdrawal/rebound causes the neurotransmission systems to go into a hyper-excitability state; if this hyper-excitability state occurs multiple times, kindling and possible neurotoxicity can occur. There is evidence that excitotoxicity may also occur as a result of repeated withdrawals. Similar to people who have been detoxified multiple times from alcohol, binge drinkers show a higher rate of emotional disturbance.[3]

m8 you're fine. You'd be surprised how little oxygen humans utilise in each breath they take from the total amount of oxygen inhaled. Low blood flow only really poses a threat in diabetics or those with aortic/pulmonic/mitral or atrioventricular stenosis.
So what? Freedom includes the right to do things that adversely effect you health. Like tobacco and fast food.
it's a moot point to compare weed and alcohol, and it's an overworked point, too.
Let's assess the merits and demerits of weed by itself.
Merits: 1000000000
Demerits: 0*
*Maybe 1 or 2 demerits but we are far from sure
I really, really like this quote.

amen clinics deal with people with brain damage, they could "discover" anything they wanted
and the people who go there tend to have worse issues then just pot use
t. bipolar fag who had to go there after a coke binge gone wrong thanks to meth
drugs are bad, news at 11.
it's only pot smokers that push the narrative pot is a health food.
I quit smoking weed but not because the health effects. If I were to continue, I'd be vaporizing it or something. I never smoked an obscene amount to worry about long term effects.
I quit because I got what I wanted out of it and kept getting diminishing returns where it wasn't even interesting anymore. Whenever I'd hang out with my smoking friends, I'd find myself just asking why I even got high in the first place. It was usually because the social situtation and I hadn't done it in a while...but the effects started becoming the same...it was just not interesting to me anymore. It was just chorelike. "Well I don't do this a lot anymore, let me remind myself what it's like...oh yeah it's not interesting".
Smoke all you want. That's what freedom (MURICA) is all about, but word of advice, don't do so if you have shit to do in the moment and smoke only when you have recreational time set aside. Same should apply to drinking.
>word of advice, don't smoke if you have shit to do in the moment
WELL, aren't you soooome sort of idiot!!!
It would impair your brains ability to function. The brain 'redirects' blood to the area of the brain that's most involved in whatever task you are doing (e.g more blood will go to the temporal lobe if you are doing something that involves deep language comprehension).
t. medfag
thats just not true i smoke every day multiple times a day and i know how bad it is for your noggin
u a doc or something?
Weed ruins my memory, for 2 days days after smoking, massive brainfog.
I can drink a couple of beers every night to get a nice feeling (never drunk) and my memory is perfect
>MUH BEER
>MUH MODERATION
>NEVER GET DRUNK
people like you are why ill never drink again absolutly ten times more autistic that pot retards
>HA HA WELL THIS ISN'T AS BAD AS THIS OTHER THING SO I WIN
Weed makes you lazy, that Is 100% true.
That said, If you try to come to my home and try to take my weed, I'm going to shoot you In the face.
I will consume whatever the fuck I please In my own home!
liberty or death and whatnot.
>people like you are why ill never drink again absolutly ten times more autistic that pot retards
What? I dont drink craft beer, drinking every day for years is not moderation you retard
This is pretty fucking stupid for several reasons
>how much is "significantly" less blood flow?
>do the patients use any other drugs (other illicits, tobacco, alcohol, etc.)?
>is this reduced blood flow proven to be detrimental enough to the brain to warrant a complete prohibition of pot?
>what are the patients individual histories?
>tons of other unindentified factors not even mentioned
This isn't a study. It's a survey. It doesn't prove anything other than what we already know. They shouldn't reach conclusions or imply pot is a dangerous drug just because a brain correlates with the same blood flow found in Alzheimer's. There needs to to be concrete proof that there are major cognitive deficiencies because of marijuana use and nothing else.
And until they find that evidence, people are going to continue to smoke weed because it doesn't harm them or affect their daily lives, and most likely haven't met anybody that has been so damaged by weed that they can't do what they did before weed.
Can't believe anti-pot propaganda/hysteria still gets media coverage. People have already figured out its nothing worse than alcohol or tobacco, and it has way more pros than cons.
Legalization is coming no matter if you like it or not, and when half the population suffers because of a weed epidemic, than you can tell me I'm wrong. But it's not going to happen.
People don't want to legalize pot not because it's dangerous, but because a lot of interest groups will lose tons of income.
we cannot know this; it's not been studied. Those are some causes of reduced blood flow, they're not the be-all and end-all of undiscovered causes of cerebral hypoperfusion.
actual study:
content.iospress.com
Weed lowers brain BDNF levels
hey medfag. it's not clear how much the blood flow is decreased and it's not clear under what conditions the decreases occurs. besides, what is the baseline?
Now, it's an entirely different issue whether the brain is receiving any amount of diminished nutrients, fresh blood, or other.
If the effects of the reduced blood flow were significant, perhaps symptoms would already be present. I mean, some people smoke a TON of pot, with wax on top.
Furthermore, the mechanism of action casuing bloodflow to decrease is unclear. Is it related to a lower heart rate, ie relaxation? Is it because pot smokers are more relaxed and are in better cardiovascular condition?
the article, as it stands, is worthless.
doctor, RN, FAAN, microbiologist here
this
But Joe Rogan said weed cures cancer bro
I disagree. Various organs, especially the brain due to its high metabolic demand, need a relatively constant blood flow and thus has an extremely small capacity for change in blood flow.
>You'd be surprised how little oxygen humans utilise in each breath they take from the total amount of oxygen inhaled
The oxygen extraction in the brain is like 60ml/L, so its pretty high.
haha fuck weedheads, literal retards
the daily mail article is stupid, read the actual study
content.iospress.com
you're right, the study doesn't amount to showing any cognitive deficits
it shows reduced blood flow, particularly to the hippocampus
it is a study, it is not a survey
what conclusions we can draw beyond "there is reduced blood supply" are non-existent
but "reduced blood supply" is, in itself, a huge deal, because no chronic changes to the brain associated with marijuana use had ever been shown prior to this study
I'm the MRI tech that does your brain scan and I smoke weed every day.
Weed can give dudes gyno and lower sperm count.
simply incorrect
i think the blood in your brain has stopped. might want to lay off the pipe, jorge
>smoke weed every day
>flag
This is why Canadians come to the US for serious medical care.
But i smoke every day and have high blood pressure. DEBUNKED
Yeah I agree for what its worth now its baseless, more research must be done.
>If the effects of the reduced blood flow were significant, perhaps symptoms would already be present
I'd say decreased cognition is an obvious symptom if we were to assume the lack of blood flow is detrimental.
>Furthermore, the mechanism of action casuing bloodflow to decrease is unclear. Is it related to a lower heart rate, ie relaxation?
As I said in another post, even if your heart rate is low the brain has a very small capacity for change in blood flow to the brain.
You need a subscription to read that study, so I'm guessing 99% of the people on here didn't even read it.
The Journal of Alzheimer's Disease isn't part of many university subscriptions either.
>implying i wasn't already trying to destroy my body as slowly as possible
I smoked weed as a teenager, and it fucked up my short term memory for years. Haven't touched it since.
THIS ARTICLE IS NOT ADDRESSING THE MOST OBVIOUS QUESTION ON OUR MINDS: IS REDUCED BLOOD FLOW ACTUALLY beneficial?
Alright John Belushi
so the article is right
fucking retarded pot heads
>IT'S A LITTLE BIT BAD BAN IT.
>THE OTHER THING THAT'S WORSE CAN STAY THO.
The end of prohibition should have been a blanket repeal from the start, not this piecemeal case-by-case series of billion dollar "wars" that the government never had a chance of winning.
Yeah you need to stop smoking that shit kiddo. OF COURSE IT ISN'T. Same way as less petrol to your engine will not make it go faster. Blood carries oxygen among others
I smoke pot like 3x a day.
I work a corporate job at a multi billion dollar corp. (think Germany)
I have never failed a task at work do to "stupidity" or "forgetting"
Im going to begin managing some businesses within my department, I dont see an issue, yet at least.
I am absolutist, exercise and good food are my only highs.
I recommend this lifestyle, you stay younger & healthy both inside and out.
Just look at Trump, the guy is 70 and he is so energized and sound minded he makes guys half his age look like a bunch of low-energy cuckolds.
Whats his secret? He never had a single drink in his life.
This is 100% true. When I used to smoke, I would get that cotton-brain headache feeling after the 2nd or 3rd smoke session. Not even that enojyable.
Marijuana should remain illegal. We need increased prison time for dealers.
Who the fuck smokes pot occasionally? Either they smoke it a handful of times when they are 13-19 or they smoke it everyday. There is no in between.
i smoked weed once, my brain fell out
dont do drugs
Captain Anecdote here reporting that when I smoked a shitload of weed, I distinctly felt weird pressure sensations inside my skull that match what this article is talking about. Once I stopped smoking, these sensations went away after a couple of weeks.

>believing a propaganda arm of the crown
You do realize that most """"""""studies"""""""""' and """""""""""findings"""""""""""' are made by people who are paid by pharmaceutical companies to make cannabis seem worse than the pills they give to people?
funny that other studies I've seen claim that cannabis actually increases blood flow to parts of the body. nobody can be believed until it is fully decriminalized, and large scale INDEPENDENT studies emerge, until then, keep calling cannabis degenerate while you continue whatever degenerate vice you possess.
thanks for correcting the record pharmashill

Thank you Jesus for helping me stop smoking pot.

pleasee be real
>I've seen claim that cannabis actually increases blood flow to parts of the body
Sure because we all know pot smokers are prone to increased physical and mental activity after taking a bong hit. Why would a depressant lead to increased blood flow. Fuck off cheech.
Excessive drug use, of any drug, will cause problems
Please study 1-2x a week marijuana use
(Cant because most weed smokers dont know what moderation means)
it's probably more complex than that. here in california you'll find potheads who were their 20s in the 60s that are still chronic users who are healthy.
but you're fine. and poo in loos sucs
Fuck it, still not worth throwing people in jail over. Deeply saddened by my friends who continue to smoke this shit, sad.
Sup, Bolivia.
Smoke wad anyone? wait is it called weed or wad I forget?..

Just legalize it already.

I really dodged a bullet with my all day everyday pot smoking for 7 years.
