"You are old, Father William," the young man said,
"And your hair has become very white;
And yet you incessantly toke on your bong—
Do you think, at your age, it is right?"

"In my youth," Father William replied to his son,
"I feared it might injure the brain;
But now that I'm perfectly sure I have none,
Why, I do it again and again."

Some advice to minimize brain damage from pot use

"The younger you start using marijuana and the more often you use it, the worse off your brain will be.

The best advice is not to use marijuana until your brain is fully developed, around the age of 25. The changes in the brain caused by early and prolonged marijuana use are serious and not worth the short term pleasure of the high."

So Obama actually did something I approve of. That makes at least three. Evidently, he has authorized Native Americans to grow and sell pot on the reservation (to anyone). Even in states where pot is illegal. Way to go Obama. :-D

Of course Plant will think this is an Evil move by O to make all Indians brain dead. 8O

Now you all can just go to your local reservation and stay away from Washington. :razz:

New evidence that marijuana causes brain damage:

smoking-cannabis-raises-risk-STROKE-Drug-significantly-narrows-blood-vessels-head

New studies show that smoking marijuana causes the blood supply to the brain to decrease by permanently shrinking blood vessels in your head. Marijuana smoking causes plaque to build up in the brain's blood vessels, cutting the blood supply to the brain and triggering strokes.

The net result is that marijuana smokers have a greatly increased risk of strokes and mini-strokes occurring at a young age, and have an overall increase of risk for strokes and related brain-related medical issues like mini-strokes and vascular dementia..

Ischemic stroke is caused by a blockage that interrupts or reduces blood flow to the brain as opposed to haemorrhagic stroke, which occurs when a blood vessel in the brain leaks or ruptures.....
In the cannabis smokers, the ischemic stroke was more likely to be caused by intracranial arterial stenosis, a condition where there is narrowing the arteries inside the skull caused by a build-up of plaque.
Intracranial arterial stenosis was found in 45 per cent of the marijuana users in the study compared to 14 per cent of the non-users.

I know hundreds of life long pot smokers & many in their late 60's, none has had a stroke.

At the moment in Oz we have a massive drug driving scam being foistered on the community, people with perfect 40 year driving records losing licenses for months or years for 'testing positive to recent cannabis use', totally arbitrary random saliva testing often busting people for a toke days ago, no impairment test required for prosecution. The science is total garbage & we have police arguing the case in moron terms for the populace- 18% of drivers involves in crashes tested positive to illegal drugs for example. Of course there is no blind test, because the state can't randomly test people at home in bed etc. But enough idiots who smoked once & didn't like it, or had a friend who became a bong ficked lounge lizard, in a democracy, bad science is good enough for an ignorant populace.

Cannabis is a medicinal herb rapidly becoming recognized for it's amazing value as medicine, food, fibre, earth repair, etc etc.

There are also many hundreds of life long cigarette smokers & many in their late 60's, none has gotten lung cancer.

But statistically, you are much more likely to get cancer if you are a cigaret smoker. Similarly, this study shows you are much more like to have a stroke if you are a marijuana smoker. :

And even if you don't get a stroke, this study shows marijuana clogs up blood vessels in the brain with plaque, reducing blood flow and increasing the risk of vascular dementia.

Bollocks, without long term & broad scale & comparative research the conclusion is not a conclusion. I can link you to studies far larger that suggest cannabis can cure or alleviate a massive range of serious medical conditions. Alcohol does far more damage than all other drugs put together but ubiquitous to all but the strictest religious countries, on tap. Cannabis has never been proven to have killed anyone, but certain morons still believe in a war against a plant. Stupid beyond words. This study convinces me of nothing.

Actually marijuana has now been proven to cause strokes, and strokes do kill people. Strokes also cripple people in horrible ways. And the cumulative effects of mini-strokes can cause vascular dementia---ie senility.

Medical science is changing rapidly. The new imaging technologies available now allow doctors to very clearly identify anomalous changes in the brain. Through standard epidemiological methods its now been shown that there are an unusually high number of strokes of a specific type in relatively young people who use marijuana. Chances are marijuana users who don't stroke are nonetheless undergoing brain damage in the form of plaque buildup, reduced blood flow to the brain, and increased danger of mini strokes and vascular dementia. I understand that you personally cannot accept these scientific findings, but these findings nonetheless represent an important advance in our understanding of the medical problems caused by marijuana use.

The medical evidence now shows that marijuana causes plaque buildup in the brain and damages blood circulation in the brain and causes a greatly increased incidence of strokes. These findings raise serious concerns about the safety of this drug.

cheers!

Eat enough Big Macs, and you're likely to have a stroke and more too.

Exclusive: Elevated CO2 Levels Directly Affect Human Cognition, New Harvard Study Shows

Image

In a landmark public health finding, a new study from the Harvard School of Public Health finds that carbon dioxide (CO2) has a direct and negative impact on human cognition and decision-making. These impacts have been observed at CO2 levels that most Americans — and their children — are routinely exposed to today inside classrooms, offices, homes, planes, and cars.

Obviously people who toke up and then get the munchies shouldn't eat Big Macs---thats like a double whammy for strokes.

I fully support Plants decision to not smoke pot. Now, lets all go out and get a nice grilled bacon cheese burger.

That's real equanimous of you there careinke. I too fully support Plants decision to be a jerk.

There are people who are climate denialists who deny the scientific evidence that CO2 causes global warming---no matter what the data says you can't convince 'em global warming is real.

And there are people who are marijuana denialists who deny the scientific evidence that marijuana causes brain damage.

Unfortunately, such people can become an impediment to dealing with the very real problems caused by climate change/marijuana.

The finding by the German doctors that marijuana use causes a build up of plaque in blood vessels in the brain is absolutely startling. Plaque buildup in the brain is thought to be one of the causes of alzheimer's disease. As boomers age, Alzheimers is going to grow in importance for this population. The possible correlation with marijuana use is very troublesome.

Prior to this study marijuana has been suggested as a possible inhibitor to plaque buildup (although double-blind tests failed to confirm it). The possibility that marijuana is CAUSING plaque build up deserves more study.
