What drug-addicted soldiers can teach us about addiction and recovery

19% of American soldiers returned from Vietnam addicted to heroin. 95% of them recovered without relapse. How?

What drug-addicted soldiers can teach us about addiction and recovery

Of all war films that offer a sense of actual combat, the documentary Restrepo is arguably closest to representing the tedium and boredom that sets in on a day to day basis—and this in one of the most contentious regions on the planet. For soldiers in the Vietnam War, weeks were filled with not much at all, making it easy for heroin to infiltrate the barracks. 


Laboratories in the Golden Triangle—Myanmar, Laos, and Thailand—were pumping out low-grade no. 3 heroin for years. Then in 1971 a chemist in Hong Kong went Walter White and started producing 99 percent pure heroin, otherwise known as no. 4. Kilo prices jumped, yet so did soldiers picking up bags from street merchants and highway stalls, even from maids who cleaned their quarters. 

By the time the war ended 35 percent of American soldiers had tasted heroin while 19 percent returned as addicts. With Nixon waging his crusade on illicit substances to control minority and radical populations, he knew this epidemic was going to be severe. A hundred thousand returning addicts who had just fought for the country could not be handled lightly. 

As Adam Alter writes in Irresistible, the marketing professor’s latest book on addictive technology, something incredible occurred. After their initial detox only 5 percent of soldiers relapsed. In the addiction community that number is unbelievable; normally only 5 percent of heroin addicts don’t relapse. 

What changed? The environment they were in. Alter writes: 

They arrived home to a completely different life. There was no trace of the jungle; the steamy summers in Saigon; the rattle of gunfire, or the chop of helicopter blades. Instead, they went grocery shopping, they returned to work, they endured the monotony of suburbia, and enjoyed the pleasure of home-cooked meals. 

Of course, PTSD and other symptoms are another story. What is incredible about this case is that it wasn’t genetics or potency that mattered—it was the shift in environmental conditions. Today, Weill Cornell Medical College clinical psychiatry professor Richard A Friedman believes that changing your environment can also shift the current opioid and obesity epidemics

Friedman cites a 2010 study at Columbia University that found proxies for stress in the form of low social status and social support resulted in fewer D2s, dopamine receptors involved in your brain’s reward network. Turns out the higher your D2 level the less likely you are to seek out pleasure in drugs such as carbs and sugars and pills. 

These receptors don’t only predict drug usage, Friedman writes, their count is also lowered by continued ingestion of substances like heroin, cocaine, and alcohol. He extends the argument for painkillers such as opioids and comfort foods. 

These people are far less sensitive to rewards, are less motivated and may find the world dull, once again making them prone to seek a chemical means to enhance their everyday life.

As our understanding of our brains evolves researchers are realizing that while addictive substances are varied, how you become addicted to a substance is similar. This is true with, as Friedman implies, cookies and meth, as well as smartphones and tablets, as Alter discusses. 

It returns to the pleasure derived in our reward network. Each drug has the same insidious effect: what provides immense pleasure at first requires stronger doses as we become accustomed to new levels of stimulation, requiring more of the substance—more food, more pain relief, more time staring at a screen. This is as true of Candy Crush as real candy. 

And so food addicts find “normal food consumption insufficiently rewarding” while olfactory stimuli creates more intense cravings in the obese than in the slim. It is measurable chemistry, but Friedman argues that environment overrules genetics and habits. Since we can’t change our genes, changing our environment appears to be the most beneficial road ahead.

Our environment has changed. Food deserts aren’t void of product; they are filled with processed sugar- and carb-heavy foodstuffs cheap to produce and cheap in the body. They provide little nutrition but much pleasure. Once you’re hooked on the taste it’s nearly impossible to alter your reward circuits. By remaining in that environment you’re likely to succumb.

Yet this isn’t only happening in poor neighborhoods. As Natalia Petrzela writes in the Washington Post, our president’s poor eating habits and lack of exercise influences the nation. She argues that he’s operating under century-old assumptions: 

His love of rich foods and leisure paradoxically trades on century-old tropes that also cast him as a kind of Everyman’s Billionaire. Until about 1920, the wealthy conspicuously consumed caloric foods and avoided exertion because few felt they could afford to do so.

Caloric foods are overwhelmingly available today in every pocket of the nation. And this is an evolutionary first. As Friedman puts it: 

There was no flourless chocolate cake on the savanna.

This “double whammy” of cheap foodstuffs and pervasive pills is a precedent our bodies are not prepared for. 

Friedman also notes something important that’s known in the addiction community: everyone has the potential to be an addict. It was long thought that certain genetic traits created the addict, but technology, obesity, and opioids prove there’s an addict lurking inside of us all. It just takes the right mixture of timing and place. Change the setting and you can recover—as Friedman observes, that might be the only factor we truly have control over.

Astronomers find more than 100,000 "stellar nurseries"

Every star we can see, including our sun, was born in one of these violent clouds.

Surprising Science

This article was originally published on our sister site, Freethink.

An international team of astronomers has conducted the biggest survey of stellar nurseries to date, charting more than 100,000 star-birthing regions across our corner of the universe.

Stellar nurseries: Outer space is filled with clouds of dust and gas called nebulae. In some of these nebulae, gravity will pull the dust and gas into clumps that eventually get so big, they collapse on themselves — and a star is born.

These star-birthing nebulae are known as stellar nurseries.

The challenge: Stars are a key part of the universe — they lead to the formation of planets and produce the elements needed to create life as we know it. A better understanding of stars, then, means a better understanding of the universe — but there's still a lot we don't know about star formation.

This is partly because it's hard to see what's going on in stellar nurseries — the clouds of dust obscure optical telescopes' view — and also because there are just so many of them that it's hard to know what the average nursery is like.

The survey: The astronomers conducted their survey of stellar nurseries using the massive ALMA telescope array in Chile. Because ALMA is a radio telescope, it captures the radio waves emanating from celestial objects, rather than the light.

"The new thing ... is that we can use ALMA to take pictures of many galaxies, and these pictures are as sharp and detailed as those taken by optical telescopes," Jiayi Sun, an Ohio State University (OSU) researcher, said in a press release.

"This just hasn't been possible before."

Over the course of the five-year survey, the group was able to chart more than 100,000 stellar nurseries across more than 90 nearby galaxies, expanding the amount of available data on the celestial objects tenfold, according to OSU researcher Adam Leroy.

New insights: The survey is already yielding new insights into stellar nurseries, including the fact that they appear to be more diverse than previously thought.

"For a long time, conventional wisdom among astronomers was that all stellar nurseries looked more or less the same," Sun said. "But with this survey we can see that this is really not the case."

"While there are some similarities, the nature and appearance of these nurseries change within and among galaxies," he continued, "just like cities or trees may vary in important ways as you go from place to place across the world."

Astronomers have also learned from the survey that stellar nurseries aren't particularly efficient at producing stars and tend to live for only 10 to 30 million years, which isn't very long on a universal scale.

Looking ahead: Data from the survey is now publicly available, so expect to see other researchers using it to make their own observations about stellar nurseries in the future.

"We have an incredible dataset here that will continue to be useful," Leroy said. "This is really a new view of galaxies and we expect to be learning from it for years to come."

Protecting space stations from deadly space debris

Tiny specks of space debris can move faster than bullets and cause way more damage. Cleaning it up is imperative.

  • NASA estimates that more than 500,000 pieces of space trash larger than a marble are currently in orbit. Estimates exceed 128 million pieces when factoring in smaller pieces from collisions. At 17,500 MPH, even a paint chip can cause serious damage.
  • To prevent this untrackable space debris from taking out satellites and putting astronauts in danger, scientists have been working on ways to retrieve large objects before they collide and create more problems.
  • The team at Clearspace, in collaboration with the European Space Agency, is on a mission to capture one such object using an autonomous spacecraft with claw-like arms. It's an expensive and very tricky mission, but one that could have a major impact on the future of space exploration.
