Opiates Killed 8 Americans In Afghanistan, Army Records Show

Eight American soldiers died of overdoses involving heroin, morphine or other opiates during deployments in Afghanistan in 2010 and 2011, according to U.S. Army investigative reports. The overdoses were revealed in documents detailing how the Army investigated a total of 56 soldiers, including the eight who fell victim to overdoses, on suspicion of possessing, using or distributing heroin and other opiates. At the same time, heroin use apparently is on the rise in the Army overall, as military statistics show that the number of soldiers testing positive for heroin has grown from 10 instances in fiscal year 2002 to 116 in fiscal year 2010. Army officials didn't respond to repeated requests for comment on Saturday. But records from the service's Criminal Investigation Command, obtained by the conservative legal group Judicial Watch, provided glimpses into how soldiers bought drugs from Afghan juveniles, an Afghan interpreter and in one case, an employee of a Defense Department contractor, who was eventually fired. The drug use is occurring in a country that is estimated to supply more than 90% of the world's opium, and the Taliban insurgency is believed to be stockpiling the drug to finance their activities, according to a 2009 U.N. study. While the records show some soldiers using heroin, much of the opiate abuse by U.S. soldiers in Afghanistan involves prescription drugs such Percocet, the Army documents show. Judicial Watch obtained the documents under the Freedom of Information of Act and provided them to CNN. Spokesman Col. Gary Kolb of the International Security Assistance Force, the NATO-led command in Afghanistan, verified the documents to CNN on Saturday. One fatal overdose occurred in June 2010 at Forward Operating Base Blessing, after a soldier asked another soldier to buy black tar opium from a local Afghan outside the base's entry control point. The first soldier died after consuming the opium like chewing tobacco and smoking pieces of it in a cigarette, the documents show. The reports even show soldier lingo for the drug -- calling it "Afghani dip" in one case where three soldiers were accused of using the opiate, the Army investigative reports show. The United States has 89,000 troops in Afghanistan. The U.S. death toll since the September 11, 2001, attacks that triggered the war has risen to more than 1,850, including 82 this year, according to the U.S. Department of Defense and U.S. Central Command. Tom Fitton, president of Judicial Watch, said his group was interested in soldiers' drug use partly because the risk was present during the Vietnam War. "You never want to see news of soldiers dying of drug use in Afghanistan," Fitton said. "Our concern is, will the military treat this as the problem that it is, and are the families of the soldiers aware of the added risk in this drug-infested country? "There is a dotted line between the uses. Prescription abuse can easily veer into heroin drug use," Fitton added. "Afghanistan is the capital of this opiate production and the temptation is great there and the opportunity for drug use all the more." The group is concerned that "there hasn't been enough public discussion, and we would encourage the leadership to discuss or talk about this issue more openly," Fitton said. In one case, a soldier bought heroin and the anti-anxiety drug Xanax from five "local national juveniles at multiple locations on Camp Phoenix, Afghanistan, and consumed them," one report states. Soldiers also distributed heroin, Percocet and other drugs among themselves, according to the reports. Another soldier fatally overdosed in December 2010 after taking several drugs, including morphine and codeine, though the drugs were not prescribed for him, the Army documents show. One female soldier broke into the Brigade Medical Supply Office at Forward Operating Base Shank and stole expired prescription narcotics including morphine, Percocet, Valium, fentanyl and lorazepam, the documents show. The investigative reports show soldiers using other drugs, including steroids and marijuana, and even hashish that was sold to U.S. servicemen by the Afghan National Army and Afghan National Police personnel, the reports state.

exploding the common myths about which foods are good for us

Myth: Salt in your diet causes high blood pressure

In the 1940s, Walter Kempner, a researcher at Duke University, North Carolina, became famous for using salt restriction to treat people with high blood pressure. Later, studies confirmed that reducing salt could help reduce hypertension. But you don't have to avoid salt entirely, says Sara Stanner, of the Nutrition Society. "Adults need a small amount of sodium in their diet to maintain the body's fluid balance."

Average salt intakes have come down in recent years, mainly due to product reformulation. But it's still the case that many of us consume too much salt – around 9g a day instead of the maximum recommended dose of 6g per day – around 75 per cent of which is in processed foods such as soups, sauces, sandwiches and processed meat.

"People often think it's really bad to add salt into cooking or on to your plate, but that forms no more than 10 per cent of your total intake," says Stanner. "So you can get people who never have salt at their table, but have a very high salt intake, while others put salt on most meals, but have a lower intake."

Myth: Carbohydrates are bad for you

"Carbohydrate-rich foods are an ideal source of energy. They can also provide a lot of fibre and nutrients," says Sara Stanner. "Potatoes, for instance, are one of the best sources of vitamin C, yet potato consumption in the UK has fallen considerably."

One of the main reasons carbohydrates have fallen out of favour is that they are perceived to be fattening. "Foods high in carbohydrates have had a rough time in the past few years, thanks to the success of low-carb diets, such as the Atkins diet," explains Juliette Kellow.

"But there's no proof that carb-rich foods are more likely to make us gain weight than any other food. Ultimately, it's an excess of calories that makes us pile on the pounds – and it really doesn't matter where those extra calories come from. More often than not, it's the fat we add to carbs that boosts the calorie content, such as butter on toast, creamy sauces with pasta and frying potatoes to make chips."

Myth: Dairy products are fattening and unhealthy

In a study by the Curtin University of Technology in Perth, Australia, slimmers on low- calorie diets which included cheese, yoghurt and milk lost more weight than those on low-dairy diets. Those on the diet including dairy also had the least stomach fat, lower blood pressure and a significantly better chance of avoiding heart disease and diabetes.

Dairy products are packed with essential nutrients that help keep us healthy, says Juliette Kellow. "As well as being good sources of protein, zinc and some B vitamins, dairy products are packed with calcium, a mineral that helps to build strong, healthy bones – and the stronger the bones are, the less likely you'll be to suffer from osteoporosis in later life."

There are loads of low-fat versions of dairy, such as skimmed or semi-skimmed milk, low-fat yoghurts and reduced-fat cheeses, she says – and low-fat versions don't mean less calcium. "Skimmed and semi-skimmed milk actually contain slightly more calcium than full-fat milk."

Myth: Red meat is bad for you

Publishing what it called "the most authoritative ever report of bowel cancer risk" last year, the World Cancer Research Fund recommended that people limit their intake of red meat to 500g a week, or just over a pound in weight. The net result of such studies is always the same – people panic.

But 500g is roughly the equivalent of five or six medium portions of roast beef, lamb or pork. "Red meat is a valuable source of minerals and vitamins, particularly iron, and we know that large numbers of women have such low intakes of this nutrient that they're at risk of anaemia. There's no need for people to think, 'I should be eating fish' when they have a steak,' provided they eat it in moderation," says Sarah Schenker.

Another myth about red meat is that it's high in fat, says Juliette Kellow, dietitian and advisor to Weight Loss Resources. "Thanks to modern breeding programmes and new trimming techniques, red meat is now leaner than ever.

Processed meat of all kinds, however, should be avoided.

Myth: Fresh is always better than frozen

Frozen fruit and vegetables can be more healthy than fresh. "Research shows that freezing vegetables such as peas as soon as they're picked – when they are at their nutritional peak – means they retain higher levels of vitamins, particularly vitamin C," says Sarah Schenker. "Once frozen, the deterioration process stops, locking in goodness. The fresh variety often travel long distances and sit on grocery shelves and along the way, heat, air, water and time can lead to a significant loss of nutrients."

Frozen or canned fruits and vegetables can also be as nutritious as fresh ones, if not more so. Again, they are often packaged within hours of being picked, retaining their nutritional value. "Always check salt and sugar levels though by comparing labels," says Sarah Schenker, of the British Dietitic Association. Even dried fruit can be healthier than fresh. "When you eat dried fruit you usually eat more than the fresh equivalent – for instance six dried apricots instead of three fresh ones. This is more calorific but you get a bigger amount of nutrients," says Schenker.

Myth: Soy eases menopausal problems

For years, the fact that Asian women have fewer menopausal symptoms has been attributed to high levels of soy in their diet. Soy products such as tofu contain natural plant oestrogens and there have been increasing claims that these might help women going through the menopause whose own oestrogen levels are dwindling.

But a University of Miami study has found that soy does nothing to abate hot flushes and bone-density loss. In fact, the women given soy appeared to experience more hot flushes than those given a placebo.

Experts including Dr Malcolm Whitehead, a menopause expert at King's College Hospital in London, aren't surprised. "In my clinical experience, women say this doesn't work for them," he says, adding that HRT is a safe and effective treatment for most women.

Others point to previous studies showing that soy can work, but the British Dietetic Association's Sarah Schenker, says, "This research has always been weak. People got excited about those early small studies, but the more research that was done, the more doubts appeared."

Myth: Brown bread is better for you than white

A darker loaf of bread does not necessarily mean it's made with whole grains – it could simply contain caramel colouring or such a small amount of whole wheat that its nutritional benefits are no different to white bread. "The real health benefits come from eating wholemeal bread instead of white," says Sarah Schenker.

Wholemeal is made from flour containing all the goodness of wheat grains. The outer husk has not been removed, so the resulting bread is much richer in fibre, protein and vitamins B1, B2, niacin, B6, folic acid and biotin. Brown bread, in contrast, is made from finely milled wheat, from which the bran has been extracted.

Look for the words "whole grain" or "100% whole wheat" on packaging and ensure the first ingredient listed is whole wheat, oats, whole rye, whole grain corn, barley, quinoa, buckwheat or brown rice. Seeded bread is even better, since it contains even more vitamins, minerals and healthy fats.

Myth: Everyone needs a lot of protein

Protein is essential for growth and development, but experts agree that most people eat far too much of it. "The Department of Health recommends that protein should make up around 10-15 per cent of your daily diet – that's around 55g for men and 45g for women," dietitian Azmina Govindji says. "Yet, according to the British Nutrition Foundation, men are probably munching their way through an average of 88g and women around 64g."

So what's fuelling this notion that we need so much? "Some diets, such as the Atkins diet, advocate speedy weight loss on cutting the carbs and piling on the proteins", Govindji says.

Another contributory factor is that in the past, it was believed nobody could eat too much protein. In the early 1900s, people were told to eat well over 100g a day and in the 1950s, health-conscious people were encouraged to boost their protein intake. But high protein can put a strain on liver and kidneys and other bodily systems.

What cannabis actually does to your brain

Archaeologists recently found a 2,700-year-old pot stash, so we know humans have been smoking weed for thousands of years. But it was only about 20 years ago that neuroscientists began to understand how it affects our brains.

Scientists have known for a while that the active ingredient in cannabis was a chemical called delta-9-tetrahydrocannabinol, or THC for short. Ingesting or smoking THC has a wide range of effects, from the psychoactive "getting high" to the physiological relief of pain and swelling. It also acts as both a stimulant and depressant. How could one substance do all that?

Meet the cannabinoid receptor

In the 1980s and 90s, researchers identified cannabinoid receptors, long, ropy proteins that weave themselves into the surfaces of our cells and process THC. They also process other chemicals, many of them naturally occurring in our bodies. Once we'd discovered these receptors, we knew exactly where THC was being processed in our bodies and brains, as well as what physical systems it was affecting. Scattered throughout the body, cannabinoid receptors come in two varieties, called CB1 and CB2 - most of your CB1 receptors are in your brain, and are responsible for that "high" feeling when you smoke pot. CB2 receptors, often associated with the immune system, are found all over the body. THC interacts with both, which is why the drug gives you the giggles and also (when interacting with the immune system) reduces swelling and pain.

 

Cannabinoid receptors evolved in sea squirts about 500 million years ago; humans and many other creatures inherited ours from a distant ancestor we share with these simple sea creatures. THC binds to receptors in animals as well as humans, with similar effects.

Tasty, tasty, tasty

Cannabis notoriously makes people hungry - even cancer patients who had lost all desire to eat.One study showed that cancer patients who thought food smelled and tasted awful suddenly regained an ability to appreciate food odors after ingesting a THC compound. There are CB1 receptors in your hypothalamus, a part of your brain known to regulate appetite, and your body's own cannabinoids usually send the "I'm hungry" message to them. But when you ingest THC, you artificially boost the amount of cannabinoids sending that message to your hypothalamus, which is why you get the munchies.

Understanding this process has actually led to a new body of research into safe diet drugs that would block those cannabinoid receptors. That way, your hypothalamus wouldn't receive signals from your body telling it to eat, and would reduce hunger cravings in dieters.

What you're forgetting

What's happening in your brain when smoking pot makes you forget what you're saying in the middle of saying it? According to the book Marijuana and Medicine (National Academies Press):

One of the primary effects of marijuana in humans is disruption of short-term memory. That is consistent with the abundance of CB1 receptors in the hippocampus, the brain region most closely associated with memory. The effects of THC resemble a temporary hippocampal lesion.

That's right - smoking a joint creates the effect of temporary brain damage.

What happens is that THC shuts down a lot of the normal neuroprocessing that goes on in your hippocampus, slowing down the memory process. So memories while stoned are often jumpy, as if parts are missing. That's because parts literally are missing: Basically you are saving a lot less information to your memory. It's not that you've quickly forgotten what's happened. You never remembered it at all.

A bit of the old timey wimey

Cannabis also distorts your sense of time. THC affects your brain's dopamine system, creating a stimulant effect. People who are stoned often report feeling excited, anxious, or energetic as a result. Like other stimulants, this affects people's sense of time. Things seem to pass quickly because the brain's clock is sped up. At the same time, as we discussed earlier (if you can remember), the drug slows down your ability to remember things. That's because it interferes with the brain's acetylcholine system, which is part of what helps you store those memories in your hippocampus. You can see that system's pathway through the brain in red in the illustration at left.

In an article io9 published last year about the neuroscience of time, we noted:

The interesting thing about smoking pot is that marijuana is one of those rare drugs that seems to interact with both the dopamine and the acetylcholine system, speeding up the former and slowing down the latter. That's why when you get stoned, your heart races but your memory sucks.

It's almost as if time is speeding up and slowing down at the same time.

Addiction and medicine

Some experts call cannabis a public health menace that's addictive and destroys lives by robbing people of ambition. Other experts call it a cure for everything from insomnia to glaucoma, and advocate its use as a medicine. The former want it to be illegal; the latter want it prescribed by doctors. Still other groups think it should be treated like other intoxicants such as alcohol and coffee - bad if you become dependent on it, but useful and just plain fun in other situations.

What's the truth? Scientists have proven that cannabis does have medical usefulness, and the more we learn the more intriguing these discoveries become. Since the early 1980s, medical researchers have published about how cannabis relieves pressure in the eye, thus easing the symptoms of glaucoma, a disease that causes blindness. THC is also "neuroprotective," meaning in essence that it prevents brain damage. Some studies have suggested that cannabis could mitigate the effects of Alzheimer's for this reason.

At the same time, we know that THC interferes with memory, and it's still uncertain what kinds of long-term effects the drug could have on memory functioning. No one has been able to prove definitively that it does or does not erode memory strength over time. Obviously, smoking it could cause lung damage. And, like the legal intoxicant alcohol, cannabis can become addictive.

Should cannabis be illegal, while alcohol flows? Unfortunately that's not the kind of question that science can answer. Let's leave the moral questions to courts, policymakers and shamans. I'll be off to the side, smoking a joint, thinking about my acetylcholine system and the many uses of the hippocampus.
