“In 1995 a group of NASA scientists experimented with drugs, literally. They studied the effects that various legal and illegal drugs have on house spiders, and specifically on the way they weave their webs. The results are both surprising and… not.
The NASA scientists suggested the possibility of analyzing the periodic structure of the spiderwebs (or lack thereof) as a means of determining the relative toxicity levels of drugs. They do not seem to have continued down that road, however; one obstacle may have been the difficulty of extrapolating a given drug’s toxicity to humans from its toxicity to spiders. Though similarities between effects on the two species do seem to exist, I’m not sure caffeine makes me feel quite like THAT. In fact, if I wove spiderwebs, that one would probably be pre-morning-cup-of-coffee.
Such questions as what the research had to do with space shuttles or Mars rovers, where the scientists got the drugs, and what happened to the spiders later unfortunately cannot be answered here. The relevant NASA briefs are cited by other academic papers and New Scientist Magazine, but aren’t themselves published on the web. The world wide one, that is.”

When Depression Drugs Don’t Help, Talking Might
Talk therapy may be a helpful supplemental treatment for people with depression who have not responded to medication, a new study from the United Kingdom suggests.
Researchers found that people with depression who had not improved despite taking antidepressants were three times more likely to experience a reduction in their depression symptoms if talk therapy was added to their treatment regimen compared with those who continued to take only antidepressants.
The study is one of the first large trials to test the effectiveness of talk therapy given in tandem with antidepressants, the researchers said.
Up to two-thirds of people with depression don’t respond fully to antidepressant treatment, and the findings suggest a way to help this group, the researchers said.
“Until now, there was little evidence to help clinicians choose the best next step treatment for those patients whose symptoms do not respond to standard drug treatments,” study researcher Nicola Wiles of the University of Bristol’s Centre for Mental Health, Addiction and Suicide Research said in a statement.
The study followed patients for one year. Future studies should examine the effectiveness of this treatment combination over the long term, as patients with depression can relapse after treatment, the researchers said.
In addition, because some patients did not improve substantially when talk therapy was added, further research is needed to find alternative treatments for this group, Wiles added.
The study included about 470 people with depression who had not responded to antidepressants after six weeks of treatment. About half received cognitive behavioral therapy — a type of talk therapy — in addition to their usual antidepressant treatment, and half continued antidepressants without the addition of talk therapy.
After six months, about 46 percent of patients in the talk therapy group experienced at least a 50 percent reduction in their depressive symptoms. By contrast, 22 percent of people in the antidepressant group improved by the same amount. By the 12-month mark, both groups experienced similar rates of improvement.
Often, talk therapy is more difficult to access than medication, the researchers said. And people may not be able to afford the treatment if their health insurance does not cover it. Only about 25 percent of Americans with depression have received talk therapy during the past year, they said.
Pass it on: People with depression who have not responded to antidepressants may benefit from the addition of talk therapy.
How Drug Company Money is Undermining Science
When Robert Lindsay chose to become a medical researcher in the early 1970s, he did not do it for the money. His field—the effect of hormones on bone—was a backwater. It was also a perfect opportunity for a young researcher to make his mark and, he hoped, help millions of people who suffered from the bone disease osteoporosis. As the body ages, sometimes bones lose the ability to rebuild themselves fast enough to keep pace with the normal process of deterioration, and the skeleton weakens. Neither Lindsay nor anyone else understood much about why this happened, but there was reason to think that hormones might play a role. Some women develop osteoporosis shortly after menopause, when their hormone levels drop sharply, perhaps upsetting that balance between bone creation and destruction. If so, Lindsay reasoned, replacing the hormones with a pill might halt or even reverse the progress of the disease. From a tiny, underfunded clinic in Glasgow, Scotland, he set up one of the first clinical trials of estrogen replacement therapy for bone loss in postmenopausal women. Lindsay’s star was rising.
His next project had big commercial implications and got the attention of the drug industry. Having moved to Helen Hayes Hospital, a rehabilitation center north of New York City, in 1984 he published work that established the minimum effective dosage of an antiosteoporosis estrogen drug called Premarin. Because the findings suggested that fighting osteoporosis was tantamount to encouraging millions of women to use the drug, it made Lindsay an important person in the eyes of the drug’s manufacturer, Wyeth-Ayerst Laboratories. Indeed, the company gave him a role as an author of its informational video Osteoporosis: A Preventable Tragedy.
By the mid-1990s, when Wyeth got caught in a patent battle over Premarin, Lindsay was a staunch Wyeth ally. He came out against approval of a generic version of the drug that would have cut into sales even though the generic form would have made it easier for osteoporosis patients to receive therapy. His reasoning was that such versions might not be precisely equivalent to the brand-name drug, a fact that can be true with certain drugs but was also a position that happened to echo the company line. “All we’re asking is that we don’t approve something now and regret it” later, he told the Associated Press in 1995. Lindsay’s close relationship with Wyeth and other drug companies carried on for decades, in ways that were sometimes hidden. He started allowing Wyeth to draft research articles and began taking tens of thousands of dollars from pharmaceutical interests that stood to gain from his research.
The scandal is not what Lindsay did so much as that his case is typical. In the past few years the pharmaceutical industry has come up with many ways to funnel large sums of money—enough sometimes to put a child through college—into the pockets of independent medical researchers who are doing work that bears, directly or indirectly, on the drugs these firms are making and marketing. The problem is not just with the drug companies and the researchers but with the whole system—the granting institutions, the research labs, the journals, the professional societies, and so forth. No one is providing the checks and balances necessary to avoid conflicts. Instead organizations seem to shift responsibility from one to the other, leaving gaps in enforcement that researchers and drug companies navigate with ease, and then shroud their deliberations in secrecy.
“There isn’t a single sector of academic medicine, academic research or medical education in which industry relationships are not a ubiquitous factor,” says sociologist Eric Campbell, a professor of medicine at Harvard Medical School. Those relationships are not all bad. After all, without the help of the pharmaceutical industry, medical researchers would not be able to turn their ideas into new drugs. Yet at the same time, Campbell argues, some of these liaisons co-opt scientists into helping sell pharmaceuticals rather than generating new knowledge.

Dropping Acid
Writing for the Morning News, Tim Doody profiles Dr. James Fadiman, investigates the back-and-forth history of government involvement with psychedelic drugs, and explores the broad benefits - both personal and societal - that could (and have) stemmed from the use of psychedelics.
Who knows, their latest findings may one day affirm some ancient hypotheses. If reality isn’t shaped with the psychically aware, self-organizing units that Giordano Bruno called monads in the sixteenth century, then perhaps it’s woven with Indra’s net, the jeweled nodes of which stretch into infinity, each one a reflection of all others. To entertain such ontologies is to re-contextualize one’s self as a marvelous conduit in a timeless whole, through which molecules and meaning flow, from nebulae to neurons and back again. If certain of these molecules connect with our serotonin receptors like a key in a pin tumbler, and open a door to extraordinary vistas, why shouldn’t we peek?

Do Psychedelics Expand the Mind by Reducing Brain Activity?
What would you see if you could look inside a hallucinating brain?
New evidence suggests drugs like LSD open the doors of perception by inhibiting parts of the brain
Despite decades of scientific investigation, we still lack a clear understanding of how hallucinogenic drugs such as LSD (lysergic acid diethylamide), mescaline, and psilocybin (the main active ingredient in magic mushrooms) work in the brain.
Modern science has demonstrated that hallucinogens activate receptors for serotonin, one of the brain’s key chemical messengers. Specifically, of the 15 different serotonin receptors, the 2A subtype (5-HT2A), seems to be the one that produces profound alterations of thought and perception. It is uncertain, however, why activation of the 5-HT2A receptor by hallucinogens produces psychedelic effects, but many scientists believe that the effects are linked to increases in brain activity.
Although it is not known why this activation would lead to profound alterations of consciousness, one speculation is that an increase in the spontaneous firing of certain types of brain cells leads to altered sensory and perceptual processing, uncontrolled memory retrieval, and the projection of mental “noise” into the mind’s eye.
The English author Aldous Huxley believed that the brain acts as a “reducing valve” that constrains conscious awareness, with mescaline and other hallucinogens inducing psychedelic effects by inhibiting this filtering mechanism. Huxley based this explanation entirely on his personal experiences with mescaline, which was given to him by Humphrey Osmond, the psychiatrist who coined the term psychedelic. Even though Huxley proposed this idea in 1954, decades before the advent of modern brain science, it turns out that he may have been correct. Although the prevailing view has been that hallucinogens work by activating the brain, rather than by inhibiting it as Huxley proposed, the results of a recent imaging study are challenging these conventional explanations.
The study in question was conducted by Dr. Robin Carhart-Harris in conjunction with Professor David Nutt, a psychiatrist who was formerly a scientific advisor to the UK government on drugs policy. Drs. Carhart-Harris, Nutt, and colleagues used functional magnetic resonance imaging (fMRI) to study the effects of psilocybin on brain activity in 30 experienced hallucinogen users. In this study, intravenous administration of 2 mg of psilocybin induced a moderately intense psychedelic state that was associated with reductions of neuronal activity in brain regions such as the medial prefrontal cortex (mPFC) and the anterior cingulate cortex (ACC).
The mPFC and ACC are highly interconnected with other brain regions and are believed to be involved in functions such as emotional regulation, cognitive processing, and introspection. Based on their findings, the authors of the study concluded that hallucinogens reduce activity in specific “hub” regions of the brain, potentially diminishing their ability to coordinate activity in downstream brain regions. In effect, psilocybin appears to inhibit brain regions that are responsible for constraining consciousness within the narrow boundaries of the normal waking state, an interpretation that is remarkably similar to what Huxley proposed over half a century ago.
Scientists invent ‘cannabis without the high’
The development may help people who smoke marijuana for medical purposes.
Alcohol is more dangerous than illegal drugs like heroin and crack cocaine, according to a new study.
British experts evaluated substances including alcohol, cocaine, heroin, ecstasy and marijuana, ranking them based on how destructive they are to the individual who takes them and to society as a whole.
Researchers analyzed how addictive a drug is and how it harms the human body, in addition to other criteria like environmental damage caused by the drug, its role in breaking up families and its economic costs, such as health care, social services, and prison.
Neuropharmacologist David Nutt, MD, of Imperial College London, and colleagues rated 20 different drugs on a scale that takes into account the various harms caused by a drug. Drugs are rated on nine harms a drug causes an individual and seven harms a drug causes society.
The scale, developed by a panel of experts called the Independent Scientific Committee on Drugs (ICSD), ranges from 0 (no harm) to 100 (greatest possible harm). It is weighted so that a drug that scores 50 is half as harmful as a drug that scores 100.
“The highest and lowest overall harm scores … are 72 for alcohol and 5 for mushrooms,” Nutt and colleagues calculate. “The ICSD scores lend support to the widely accepted view that alcohol is an extremely harmful drug both to users and to society.”
Alcohol was found to be the most harmful drug to society and the fourth most harmful drug to users.
The findings should come as no surprise: Alcohol has been linked to more than 60 diseases.
Hold on a sec, there!
Internet addiction has same effect as cocaine on brains: study
This is your brain on the Internet: Messed up where there should be connections for making decisions and having normal emotions.
Results of a new study suggest people who cannot control, cut back or stop their use of the Internet have abnormal white matter structure in the brain similar to what is seen in cocaine and crystal-meth addicts.
According to the study’s authors, as the number of people logging onto cyberspace soars, “Internet addiction disorder” — which is poised to enter the official lexicon of psychiatric illnesses — “is becoming a serious mental-health issue around the world.”
The disorder, as described in the study published this week in the journal PLoS One, is defined as “problematic” or pathological computer use that can cause “marked distress” and interfere with school, work, family and social relationships.
For their study, led by Hao Lei of the Chinese Academy of Sciences in Wuhan, researchers scanned the brains of 17 teens and young adults, aged 14 to 24, with Internet addiction and 16 healthy “controls” of similar age.
People were classified as suffering from Internet addiction disorder, or IAD, based on a questionnaire that included the following: Do you feel preoccupied with the Internet? Do you stay online longer than originally intended? Do you feel restless, moody, depressed or irritable when attempting to cut down or stop Internet use?Yeah, yeah … internet addiction. I’ve got a significant problem with this claim, and this whole way of thinking, as do many others.
It all boils down to this: “Internet use” is not just one thing, it is a mosaic of behaviors. How can we claim addiction if people use the internet in so many different ways? Sure, there’s certain specific behaviors and tendencies that are manifested online that share symptoms with traditional “addiction”, whatever that is. But everyone uses the tool in their own way. As neuro writer Vaughan Bell says:
“internet addiction not possible because no single behaviour is associated with the internet. The concept is broken.”
The internet is not heroin. It is not a specific chemical affecting a specific biological response and eliciting a specific molecular feedback loop of reward, tolerance and dependence. American and European psychiatrists do not recognize “internet addiction” as a real condition in their diagnostic manuals.
Rather, I think we should wonder what is behind these curious claims, and treat that behavior. The internet is just an expression of a deeper neurological condition.

Physicians who prescribe opioid drugs to patients with neuropathy (nerve pain) ought to consider recommending cannabis as an alternative therapy, according to a peer-reviewed paper published online this week in the Harm Reduction Journal.
“There is sufficient evidence of safety and efficacy for the use of (cannabis/cannabinoids) in the treatment of nerve pain relative to opioids,” the commentary states. “In states where medicinal cannabis is legal, physicians who treat neuropathic pain with opioids should evaluate their patients for a trial of cannabis and prescribe it when appropriate prior to using opioids. … Prescribing cannabis in place of opioids for neuropathic pain may reduce the morbidity and mortality rates associated with prescription pain medications and may be an effective harm reduction strategy.”
The author notes that between the years 1999 and 2006, “approximately 65,000 people died from opioid analgesic overdose.” By contrast, he writes “[N]o one has ever died from an overdose of cannabis.”
In clinical trials, inhaled cannabis has been consistently shown to reduce neuropathic pain of diverse causes in subjects unresponsive to standard pain therapies.

Digital Narcotics May Be the Future of Drugs
by Olivia Solon
Technologists will become the next drug dealers, administering narcotics through brain stimulation, according to Rohit Talwar, the founder of Fast Future Research, speaking at Intelligence Squared’s If conference.
Talwar was charged by the government to investigate the drugs landscape over the next 20 years, exploring scenarios going beyond the traditional model of gangs producing and shipping drugs around the world.
He described how the world of genomic sequencing and services such as 23 and Me open up possibilities for tailoring drugs to the individual, delivering effects based on your physiology — which could apply just as effectively to narcotics as it could medicines.
He cited research from the University of California, Berkeley where neuroscientists were able to replicate images people were seeing based on the brain patterns of activity. When combined with transcranial magnetic stimulation — which has been used to inhibit brain functions such as the ability to speak or remember — it opens up the possibility of electronically delivering targeted highs.
He said: “You could also visualize the experience and then tailor the effect to what you want. This nano-bio-info-cogno convergence gets us into some very interesting spheres.”
One scenario he imagines would make use of biological proteins manufactured with information-processing technology to deliver effects that could be triggered by electromagnetic stimulation. He imagined that they could be used in a club environment where the DJ would release nanoparticles that the audience could ingest. These could then be used to trigger the desired state at a particular point during his or her set using an electrical stimulus (from a headset) into the crowd’s brains.
“The more we can understand the brain, the more we can deliver positive effects such as improved memory function. Do you want to get high? Mellow? Actually I want to live my life in my head as half-human half-cat,” he joked.
High IQ linked to drug use
The “Just Say No” generation was often told by parents and teachers that intelligent people didn’t use drugs. Turns out, the adults may have been wrong.
A new British study finds children with high IQs are more likely to use drugs as adults than people who score low on IQ tests as children.
Researchers discovered men with high childhood IQs were up to two times more likely to use illegal drugs than their lower-scoring counterparts. Girls with high IQs were up to three times more likely to use drugs as adults.
“We suspect they may be more open to new experiences and are more sensation seeking.”
Hmmmmm…
3D Printing & Augmented Reality to Help Model Drugs
They are the two big tech buzzwords of the moment. Now a combination of 3D printing and augmented reality can help researchers design more effective drugs.
At Arthur Olsen’s Molecular Graphics Lab at the Scripps Research Institute in La Jolla, California, research teams model biological viruses - including HIV - and attempt to work out what kind of proteins and ligand molecules can latch onto them, to see which might inhibit or disable them.
As Olsen shows in this video, 3D printing allows them to create accurate plastic models of virus segments and the potential drug molecules. With smart use of magnets they can be made to self-assemble, too.
‘Magic Mushrooms’ Statistically Shown to Improve Long Term Psychological Health
The psychedelic drug in magic mushrooms may have lasting medical and spiritual benefits, according to new research from Johns Hopkins School of Medicine.
The mushroom-derived hallucinogen, called psilocybin, is known to trigger transformative spiritual states, but at high doses it can also result in “bad trips” marked by terror and panic. The trick is to get the dose just right, which the Johns Hopkins researchers report having accomplished.
In their study, the Hopkins scientists were able to reliably induce transcendental experiences in volunteers, which offered long-lasting psychological growth and helped people find peace in their lives — without the negative effects.
“The important point here is that we found the sweet spot where we can optimize the positive persistent effects and avoid some of the fear and anxiety that can occur and can be quite disruptive,” says lead author Roland Griffiths, professor of behavioral biology at Hopkins.
Giffiths’ study involved 18 healthy adults, average age 46, who participated in five eight-hour drug sessions with either psilocybin — at varying doses — or placebo. Nearly all the volunteers were college graduates and 78% participated regularly in religious activities; all were interested in spiritual experience.
Fourteen months after participating in the study, 94% of those who received the drug said the experiment was one of the top five most meaningful experiences of their lives; 39% said it was the single most meaningful experience.
The study was published in the journal Psychopharmacology
