Psilocybin Desynchronizes the Human Brain (nytimes.com) 80
An anonymous reader quotes a report from the New York Times: The image, as it happens, comes from dozens of brain scans produced by researchers at Washington University School of Medicine in St. Louis who gave psilocybin, the compound in "magic mushrooms," to participants in a study before sending them into a functional M.R.I. scanner. The kaleidoscopic whirl of colors they recorded is essentially a heat map of brain changes, with the red, orange and yellow hues reflecting a significant departure from normal activity patterns. The blues and greens reflect normal brain activity that occurs in the so-called functional networks, the neural communication pathways that connect different regions of the brain.
The scans, published Wednesday in the journal Nature, offer a rare glimpse into the wild neural storm associated with mind-altering drugs. Researchers say they could provide a potential road map for understanding how psychedelic compounds like psilocybin, LSD and MDMA can lead to lasting relief from depression, anxiety and other mental health disorders. "Psilocybin, in contrast to any other drug we've tested, has this massive effect on the whole brain that was pretty unexpected," said Dr. Nico Dosenbach, a professor of neurology at Washington University and a senior author of the study. "It was quite shocking when we saw the effect size." Brian Mathur, a systems neuroscientist at the University of Maryland School of Medicine in Baltimore, says these findings cannot show exactly what causes the therapeutic benefit of psilocybin, but "it's possible psilocybin is directly causing" the brain-network changes. That, or it is creating a psychedelic experience that in turn causes parts of the brain to behave differently.
The next step is to determine whether psilocybin's blood-flow changes in the brain or its direct effects on neurons, or both, are responsible for the brain-network disruptions. "The best part of this work is that it's going to provide a means forward for the field to develop further hypotheses that can and should be tested," Mathur says.

I know a number of reasonably successful people who smoke weed regularly. There is no "one naturally precludes the desire to do the other", you're just making that up. A person can go home after a hard days work and smoke some weed and wake up for work the next day and do it all over again just fine. A lazy person will likely use it as a crutch to be lazy though.

I absolutely loved mushrooms. A couple of decades ago I "experimented". Well... to be honest, if we're going to use a euphemism I probably went professional in a few things. I experimented with a lot of things. But it all had it's time and place, and I'm a well-adjusted guy in my 50s. I don't even use pot.
I have no intention of revisiting any of it. The only exception is mushrooms. In fact, I've got some in my home safe, awaiting the right time. They were that good. Reasonably well-behaved, appropriate duration, easier descent... and sleep is possible in relatively short order. Unlike, say, acid... ugh.
Now, I cannot speak to the therapeutic benefits of mushrooms. I do not recall ever taking something that one could reasonably call a micro-dose. When I did psychedelics, I always wanted to get pretty deep into the rabbit hole. But I can say that they overloaded my empathy circuit. If I watched a movie while on them, I was completely in tune with the emotional context. I "got" what the director intended. Or at least so it seemed. Your evaluation of your state is hopelessly compromised.
But I can say they came with a mental unlocking that probably does persist. I never noticed at the time... but I do know that after my period of excess I was a distinctly different person. I could relate to others in ways that were completely foreign to the introverted guy I had been. I had emotional context I didn't have before. And those changes remained. Don't put me in front of a gym full of high school students to tell them about the dangers of drugs. The most honest thing I can say is that, "It's complicated."
But despite taking unreasonable doses of mushrooms, LSD, ketamine, and (only twice) mescaline, I never once had a bad trip. On anything. I'm fully aware that this is not true for everybody.
YMMV. IANAL IANAD etc..

Mushrooms are probably the safest way to get a trip. You can't overdose on them. You can't get addicted to them. As long as you take the correct mushrooms and *be supervised*, ideally by someone not high, then you should be fine. Why supervised? Well the most likely thing to hurt you on a mushroom trip is yourself accidentally. Having someone there to stop you doing something silly is a good idea.

Summing up research: Ketamine, Psilocybin, DMT, etc - all essentially do the same thing: They dysregulate independent neural functions, which essentially control the brain's "bucketization" category, or how we process stimuli into different stereotypes; causing a "blended consciousness" experience, where IQ, memory, positive and negative subjective emotional inputs are simultaneously experiencing synaptic tagging - or more interestingly - cortical expansion with TOP plasticity enhancements.
These are the same things experienced by those in deep, meditative states, or those with adrenaline-infused NDE/ADE experiences; essentially giving spiritual, metaphysical changes in belief structure as imagination, IQ, memory, and feelings merge into a powerful blending of multi-functional neural activity.
