Research  to the rescue. High-tech brain scans reveal that psilocybin inhibits  blood flow in parts of the brain that regulate sensory input. Less blood  flow means less regulation. Flooded with perceptions, a psilocybinized  brain can help PTSD patients reprogram their fears, Doblin says. New  tools also provide new insight into LSD's ego-dissolving "catharsis  effect." And the ecstasy chemistry: MDMA reduces blood flow in the  fear-processing amygdala while increasing blood flow in the prefrontal  cortex, which facilitates our ability to put things into context.
"With MDMA, the fear circuitry is reduced," Doblin explains. This  helps PTSD patients remember and re-examine long-buried aspects of their  traumas. Aided by MDMA, "these memories don't immediately go straight  to fear." Say you were traumatized by a bat-wielding, red-hatted  assailant. Under MDMA, "the neural pathways connecting bats, red hats  and fear are not so strong." Recontextualized in an MDMA-activated  prefrontal cortex, triggers lose their power -- sometimes forever, he  says.
 "Under the influence of MDMA, people can make emotional changes that  persist after the MDMA is out of their systems." On MDMA, "you operate  on this much smoother level, and then you lose it -- but not all of it.  You get so much material from that experience, which you can learn to  integrate."
 This doesn't mean you can recover by hitting a few raves. A key theme  of the medical-psychedelics movement is that it's medical. These drugs  are so strong and long-lasting that, for clinical use, Doblin says they  must be administered in "a safe, supportive, controlled setting"  overseen by professionals.
    This is really good news, I just hope it comes to fruition. Enough mind altering drugs are used anyway so why not use some clinically that may actually have some long lasting positive effects.
