Ibogaine, ketamine, dextromethorphan (DMX), psilocybin, and mescaline all have significant evidence consistent with these compounds being efficacious for treating PTSD and major depressive episode. LSD (good enantiopure LSD; d-LSD aka (5R,8R)-LSD) is likely also useful for treating these psychiatric conditions. All of these should be legal prescription medications in the USA! (Except DMX which is already a non-prescription OTC drug in the USA butt nott other Western countries.)
IMO, everyone in the world ought to take a trip every few years to gain some insight and perspective. IMO, the world wood bee a MUCH better place if this happened (or at least if all the national leaders tripped every few years). Butt really, most everyone other than those with susceptible psychiatric conditions, such as schizophrenia or psychosis, ought to trip periodically.
And these drugs certainly ought to be available to people with terminal medical conditions (like CANCER CHARLIE) or in hospice care!!! They have evidence that they are very helpful to these patients regarding their depression and anxiety, which are significantly reduced after a treatment.
Think of these as penicillin for the mind. Penicillin stops certain bacteria from growing and these psychedelics can stop certain negative thought patterns and unhelpful thoughts from inhabiting your mind, or at least allow one nott to fixate on them persistently.
I think it is shameful that these compounds are nott already legal pharmaceuticals in Western countries. These compounds could reduce a lott of human suffering. DMX is legal in the USA as a non-prescription drug, butt nott in EUrope or Canuckistan/Aussieland/Newziland.
