Two recent events have dimmed some of the glow of marijuana, the world’s most widely consumed illegal drug. The first event is a study showing possible adverse effects of chronic marijuana use, presented at the recent annual meeting of the Society for Nuclear Medicine (SNM) in San Antonio, Texas.

According to the scientists who conducted the study, chronic use of marijuana causes a decrease in some brain receptors that bind with THC, the psychoactive chemical in cannabis. Using a PET scan to capture images of the brain, the study leaders found that chronic consumption of marijuana can lead to a decreased number of cannabinoid CB1 receptors specifically. These receptors play roles in pleasure, appetite, pain tolerance and other psychological and physiological functions throughout the body. The extent to which this may cause mental or physical troubles remains to be determined.

Employing PET scan imaging, the researchers examined the brains of chronic marijuana users, and found that CB1 receptor activity was reduced by as much as 20 percent. Upon cessation of marijuana use, receptor activity returned to normal, suggesting no lasting adverse effects. The study involved injection of a radioactive isotope into the bodies of chronic marijuana users, and then observing cannabinoid CB1 receptor activity via the PET imaging, which takes a nuclear image of biological activity.

The decrease of CB1 activity is known as “downregulation.” And while no specific adverse effects of this occurrence in marijuana users has been identified by researchers, there is a presumption among them that the decrease is not good.

Yet the downregulation of CB1 receptor activity may hold promise for those who are overweight. In sharp contrast to the ominous undertones of the SNM research, a tantalizing study conducted in Europe and reported in the British medical journal Lancet in 2005, showed that downregulation of the CB1 receptor in obese people can lead to a leaner body type. In that study, suppression of CB1 activity in obese subjects resulted in reduced waist size, improved blood levels of HDL-cholesterol and triglycerides, and improved insulin activity and overall reduction of symptoms of metabolic syndrome. This study suggests that downregulation of CB1 activity, at least in obese people, may be a good thing. So can pot help overweight people to slim down? The jury is out on that one.

Against of all of this science chatter about the negative or positive implications of reduced CB1 activity, another force is at work that may trouble pot smokers. The Dutch cabinet is moving to restrict access to the famed marijuana café’s of the Netherlands, limiting patronage to Dutch citizens, and forbidding access to foreigners. The Dutch bureau of tourism estimates that approximately twenty percent of all travelers to the Netherlands take advantage of the “coffee shops” that sell marijuana. Tourism officials in Amsterdam are fighting the proposed change of access, decrying that such a move would damage tourism to that city.

So what are we to conclude from all the activity around marijuana? There is an adage that the difference between a medicine and a poison is the dose. It is possible that very high use of marijuana may result in negative changes in overall function of the central nervous system, though this needs to be further established. At the same time, we may possibly have in pot a weight control agent. This seems to contradict the increase in appetite that most marijuana users experience. Further investigation into this is unquestionably needed.

And it doesn't sound good for tourists to Amsterdam wanting to go to those cafes. Oh, what will they do?

Maybe they can legalize it here in weight control clinics. I guess it won't matter if there's the possibility of the brain not functioning as well, as long as they're skinny. :rolleyes::D

nobody has said that. There are known risks to smoking anything.


besides, all down relgulation is, is the receptors in the cells for the THC molecule simply being taken down by the cell. The system is over saturated with THC so the body doesn't need as many of them. If that person stopped smoking within a few weeks the reverse would happen and there would be and up regulation of the same receptors, meaning the cell would gain them.

from the same article:

the bold part is what happens when there is an up regulation of the CB1 receptor as it seems to be tied to appetite as one can infer from the down regulation being an appetite suppressant and helping people to lose weight.


Vilified by opponents and championed by users, marijuana remains a highly disputed drug. Studies show that occasional or medical marijuana use is far less harmful than use of either tobacco or alcohol, both of which are responsible for the deaths of hundreds of thousands of Americans each year. At present, not one marijuana-related death has ever been reported. Medical applications of marijuana, for pain, appetite and glaucoma are increasingly well established. And information from the U.S. government itself shows likely benefits of marijuana for the treatment of degenerative disorders of the nervous system.


and yet hemp/pot is so insanely regulated that it can't even be used for research (this study wasn't on the plant itself but on it's affects on users) which is asinine

Dope is for dopes. Unlike alcohol, dopers smoke/eat it to get stoned. No two ways about it. That is not true of most people that drink. Also, the strength level of marijuana grown today has increased greatly from that available 30 to 40 years ago.

From a health perspective, bad trips from smoking pot are prevalent such as getting claustrophobia, feel like peeling you off the wall, having to get out of a building. This shit is doing something to your body that is not good. And yes, I have experienced these things from smoking it.

tobacco causes lung cancer. alcohol causes liver disease.

this article says CHRONIC use will cause these symptoms.

People drink alcohol to feel the effects of alcohol. Simple as that. Not everyone who drinks alcohol gets drunk (in small amounts), and not everyone who smokes marijuana gets "stoned" (in small amounts).

Believe it or not, some people are able to smoke small amounts of marijuana and feel relatively minor effects. They are still able to function, still able to use their brain, they still retain normal motor skills and all that.

Regular pot smokers can smoke a small amount and go out and do stuff and no one would ever know they smoked because they aren't "acting stoned".

I don't recommend it, but it is possible for some people to smoke and think, smoke and study, smoke and clean up their home, smoke and do work, smoke and do pretty much anything they can do sober. The effects of marijuana are different from person to person, with their level of experience being a HUGE factor.

Some people may get stupid and "stoned" from having a puff, but not everyone does, so you can't say that's the only reason people smoke.


Also, the strength level of marijuana grown today has increased greatly from that available 30 to 40 years ago.

Oh boo hoo you didn't stay calm and had a bad trip. I'm guessing you survived that ordeal?

For some people, lots of marijuana can cause anxiety attacks, but again, it's not simply the marijuana itself, but also the setting, the circumstances, and the mental state of the person doing the smoking. It won't kill you though, it'll just make you uncomfortable and anxious for a while, which is a good deterrent for people who shouldn't be smoking it.


Trust me buddy, you aren't the only one here who are familiar with marijuana.

Kudos to the author for his excessive use of the word chronic in a story about weed. Excellent.

And regarding that use, remember....everything in moderation. ;)

Most people that drink like the taste of it. There is nothing tasteful in smoking weed. It is smoked for the effect. You fail there. Drugs affect people differently. At least you got that part right. BTW, if it takes more than one joint to get high, you are an addict and worthless as piss on a hot rock.

The reason many want to legalize it is so they do not get in trouble with the law and fear of losing their job. Like I said, drug testing will continue if pot is legalized. Employers do not want drug addled employees. Even a hypocrite like you should understand that fact.

That's perfectly fine if employers want to test their employees. Personally I don't agree with firing people for what they do when they aren't on the job, but that's up to the employer.

This has nothing to do with marijuana laws. The discussion about marijuana laws has to do with the role of the government in dictating what you can put into your body, the reasonability of such laws based on health and social concerns, and the cost of such laws from law enforcement. This is about the government, not the employers.


Like I said many times already, I don't use marijuana or any other illegal substances. This is not about "not wanting to get in trouble" or about "losing my job". This is about sane policy based on evidence, reason, and even a little common sense.

Legalization will bring legal challenges in court for hiring practices and firing present employees. If you think that the 9th Circut would not uphold an employees lawsuit claiming discriminatory practices or that his rights were violated, you are nuts.

There are many things that are bad for you. Marijuana is one of those substance. It is just good common sense to keep it illegal so that usage will not increase. Legalization would result in government taxation and the hiring of more union workers.

and yet all you have is anecdotal evidence and not facts, even this article is only talking about long term habitual use that they aren't even sure if it IS bad or not for the CB1 to be down regulated. Sorry man that's just not enough to make it illegal to the extent that it is.

the legalization should go back to the other thread, this isn't about that.

More Americans agree with me that it should not be legal. Sorry man; that's just how the mop flops.

Increased Support for Legalization of Marijuana

The public is divided over whether the use of marijuana should be legal or not; half (50%) oppose legalization while nearly as many (45%) favor legalizing marijuana. Support for legalizing marijuana is up slightly since March, 2010; and over the past 40 years – drawing on trends from Gallup and the General Social Survey – support for legalizing marijuana has never been higher.

Young people under the age of 30 favor legalizing the use of marijuana by a 54%-42% margin. Opinion is divided among those in middle age groups. Those 65 and older are broadly opposed to legalization (66% illegal, 30% legal).

A slim majority of Democrats (53%) favor legalizing the use of marijuana, while 43% are opposed. Support is particularly high among liberal Democrats, 66% of whom support legalization. Republicans, by contrast, oppose legalization by a wide 67%-30% margin and there are only modest differences between conservative Republicans and moderate and liberal Republicans– majorities of both groups oppose legalization. Independents are divided in their views: 49% say marijuana should be legal, 45% illegal.

About as many favor as oppose legalizing marijuana among those with some college experience. By contrast, those with no college experience oppose legalization by a 55%-40% margin.

Combine that with this conservative commissioned poll (http://www.huffingtonpost.com/2009/05/06/majority-of-americans-wan_n_198196.html) that says 52% of Americans favor legalization and I'd say the pendulum is swinging away from you.

Get off the bong.Another one of Zogy's bullshit polls states that Obama should get tough with Israel to stop the settlements by a 40% for to 26% against. It does not get any more squirrely than that.

Growing marijuana is not legal in any state even in a f....up state like CA. Plus, holding up Arnold as poster boy for legal marijuana, who is a lying scum bag politician, really advances the cause.

Let's see, do you live in a red or blue state?
