Maybe talk to First Responders / Law Enforcement and Emergency Room M.D.'s about the risks involved with taking an amphetamine based hallucinogenic before trying on PTSD patients. Not sure on the success rate of Eye Movement Desensitization and Reprocessing (EMDR) but as a first responder with first hand experience, I would much rather try something with less side effects than a highly destructive chemical based drug. It's a subject that I spent the better part of seven years learning how to cope with. Probably the last person anyone would want to tangle with is someone who has been trained to deal with life threatening situations and is now under the influence of a hallucinogenic and is amped up on amphetamine (super-human) strength. Bad idea
