Can Psychedelics Make Us More Content?

Recent research in psilocybin, LSD, and MDMA, which all affect our serotonin receptors, suggest these substances can help make us content. 

Among the many professed life goals hash-tagged on social media—beauty (205.2 million on Instagram), success (25.5 million), money (26.1 million), power (19.7 million), and handstands (4.3 million)—contentment (240k) doesn’t fare well. We generally want more than we have, which doesn’t promote a content life. Yet many common psychological disorders, including anxiety and depression, are rooted, at least in part, in our lack of contentment. We’re not okay where we are, so we fret about the future, what we don’t have, what our peers do have, and how we’ve arrived at this point now. 

There’s a strong argument for pursuing a content life, especially in a country as rich in opportunity as America. As he writes in his book, The Hacking of the American Mind, Robert Lustig labels serotonin the contentment molecule. He contrasts it with dopamine, the neurotransmitter responsible for our pursuit of pleasure. We love the quick squirt of dopamine when thinking highly of ourselves—#blessed (83.2 million). The slow and steady path toward contentment doesn’t get as much traction in an age of instant gratification. 

Of the many ways Lustig suggests cultivating contentment—meditation, cooking, exercise, mindfulness, volunteering, conversations—psychedelics is an interesting one. As he recently told me, he’s not promoting these substances per se. Science is what matters, and after reading a highly circulated Michael Pollan article on psychedelics aiding people during end-of-life care, he decided to investigate the topic. Even then he spent a lot of time making sure he got the science right:

When my editor and I sat down to discuss Chapter 8 [“Picking the Lock to Nirvana”] that was the chapter we discussed the most. We spent five times as much time on Chapter 8 as we did on any other chapter because we wanted to make sure we got it right, because it potentially has a propensity for abuse.

Lustig found that certain psychedelics do indeed relate to contentment. The structure of serotonin, a monoamine neurotransmitter responsible for making us feel content, was confirmed in 1953. Though researchers initially discovered its presence in the brain, serotonin is predominantly found in our gastrointestinal tract, a fact that is helping us better understand our emotional relationship with food. 

The serotonin-1a receptor is responsible for contentment, the serotonin-2a receptor for mystical experiences. Psilocybin and LSD bind to both, whereas mescaline only binds to 2a—hallucinations without emotional satisfaction. That might explain why a host of recent research in psilocybin, the active ingredient in “magic mushrooms,” and LSD are showing beneficial results in a variety of cognitive disorders. As New Scientist reports, 

Mental illness has reached crisis proportions, yet we still have no clear links between psychiatric diagnoses and what’s going on in the brain – and no effective new classes of drugs. There is one group of compounds that shows promise. They seem to be capable of alleviating symptoms for long periods, in some cases with just a single dose. The catch is that these substances, known as psychedelics, have been outlawed for decades.

That is changing, slowly, as more organizations explore the therapeutic potential of psychedelics for healing trauma, addiction, depression, anxiety, fear of death, and other mental and emotional afflictions. This could open new doors in treating patients across the spectrum, something the usual course of treatment—selective serotonin reuptake inhibitors (SSRIs), which boost serotonin by blocking neuronal reabsorption—is proving ineffective at. Though 8.5 percent of Americans take SSRIs, the efficacy rate hovers at only 20 percent. 

SSRIs require regular doses, whereas a single 25 mg dose of psilocybin showed a reduction in depression for three weeks in 100 percent of volunteers, with 25 percent of participants still feeling the benefits three months later. Brain scans show neurons firing more synchronously after psilocybin and LSD, which plays a role in reducing each person’s obsession with their ego, the very part of their identity promoting certain cognitive disorders. (Interestingly, flow states exhibit similar results in ego-reduction.) 

Research in MDMA, which Lustig says also binds to dopamine receptors, is showing similar promise. Used in couples counseling before being outlawed during the Nixon administration, it is now being fast-tracked by the FDA for review and potential approval after showing promising results treating PTSD in soldiers and other sufferers. 

While MDMA does not exhibit the same intense mystical qualities of these other substances, it appears to help PTSD victims recall memories without the trauma associated with the event thanks to the release of oxytocin—and by binding to serotonin receptors. As Lustig writes about MDMA,

It heightens excitement and sexuality and postpones fatigue and sleepiness, because the dopamine receptor is activated; it increases euphoria, because the serotonin-1a receptor is activated; and it even gives the added bonus of minor hallucinations, because the serotonin-2a receptor is activated, although the bonus “mystical experience” is not part of the portfolio. 

When sufferers of PTSD take part in memory reconsolidation, in which they recall painful experiences, after ingesting MDMA, there is no actual pain. They’re able to integrate their traumatic experience without the accompanying anxiety. Three weeks into my divorce a dose of MDMA served as a powerful therapeutic tool: I was able to recognize the arc of life as continuous, helping me moving beyond negative thoughts of finality. Perspective is everything.

Lustig’s warning above about addiction isn’t particularly relevant to psychedelics in the way opioids are physical addictive, though people do become hooked to the feelings that certain substances, especially MDMA, provide. If psychedelics are valuable their clinical potential needs to be studied and, if proven effective, implemented. Otherwise it becomes a wild west similar to the opioid crisis, with people dosing themselves with no knowledge of efficacy or strength.

Current interventions, while raking in billions for the pharmaceutical industry, are generally not working. We shouldn’t outright dismiss these pills; my six months on Xanax dealing with anxiety disorder proved beneficial. Individual chemistry needs to be considered. But this also means we need to stop treating this hormone as illegal and that one as sanctioned if we truly want to find solutions to chronic cognitive and emotional pain. That just might mean integrating psychedelics into our healing regimen.

Scientists study tattooed corpses, find pigment in lymph nodes

It turns out, that tattoo ink can travel throughout your body and settle in lymph nodes.

In the slightly macabre experiment to find out where tattoo ink travels to in the body, French and German researchers recently used synchrotron X-ray fluorescence in four "inked" human cadavers — as well as one without. The results of their 2017 study? Some of the tattoo ink apparently settled in lymph nodes.

As the authors explain in the study — they hail from Ludwig Maximilian University of Munich, the European Synchrotron Radiation Facility, and the German Federal Institute for Risk Assessment — it would have been unethical to test this on live animals since those creatures would not be able to give permission to be tattooed.

Because of the prevalence of tattoos these days, the researchers wanted to find out if the ink could be harmful in some way.

"The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body," they write.

It works like this: Since lymph nodes filter lymph, which is the fluid that carries white blood cells throughout the body in an effort to fight infections that are encountered, that is where some of the ink particles collect.

Titanium dioxide appears to be the thing that travels. It's a white tattoo ink pigment that's mixed with other colors all the time to control shades.

The study's authors will keep working on this in the meantime.

“In future experiments we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible bio-distribution of tattoo ink ingredients throughout the body. The outcome of these investigations not only will be helpful in the assessment of the health risks associated with tattooing but also in the judgment of other exposures such as, e.g., the entrance of TiO2 nanoparticles present in cosmetics at the site of damaged skin."

Climate change melts Mount Everest's ice, exposing dead bodies of past climbers

Melting ice is turning up bodies on Mt. Everest. This isn't as shocking as you'd think.

Surprising Science
  • Mt. Everest is the final resting place of about 200 climbers who never made it down.
  • Recent glacial melting, caused by global warming, has made many of the bodies previously hidden by ice and snow visible again.
  • While many bodies are quite visible and well known, others are renowned for being lost for decades.

The bodies that remain in view are often used as waypoints for the living. Some of them are well-known markers that have earned nicknames.

For instance, the image above is of "Green Boots," the unidentified corpse named for its neon footwear. Widely believed to be the body of Tsewang Paljor, the remains are well known as a guide point for passing mountaineers. Perhaps it is too well known, as the climber David Sharp died next to Green Boots while dozens of people walked past him- many presuming he was the famous corpse.

A large area below the summit has earned the discordant nickname "rainbow valley" for being filled with the bright and colorfully dressed corpses of maintainers who never made it back down. The sight of a frozen hand or foot sticking out of the snow is so common that Tshering Pandey Bhote, vice president of Nepal National Mountain Guides Association claimed: "most climbers are mentally prepared to come across such a sight."

Other bodies are famous for not having been found yet. Sandy Irvine, the partner of George Mallory, may have been one of the first two people to reach the summit of Everest a full thirty years before Edmund Hillary and Tenzing Norgay did it. Since they never made it back down, nobody knows just how close to the top they made it.

Mallory's frozen body was found by chance in the nineties without the Kodak cameras he brought up to record the climb with. It has been speculated that Irvine might have them and Kodak says they could still develop the film if the cameras turn up. Circumstantial evidence suggests that they died on the way back down from the summit, Mallory had his goggles off and a photo of his wife he said he'd put at the peak wasn't in his coat. If Irving is found with that camera, history books might need rewriting.

As Everest's glaciers melt its morbid history comes into clearer view. Will the melting cause old bodies to become new landmarks? Will Sandy Irvine be found? Only time will tell.
