I am of the opinion that resolving trauma that causes a person to "zone out" and sleep walk through life can have equivalent effect to psychedelics. I've done both, so I can compare them. Cognitive Behavioral Therapy, Dialectic Behavioral Therapy, Cognitive Processing Therapy and Wisemind done with a knowledgeable therapist can produce excellent results. Meditation and mindfulness (pay attention to what you pay attention to) are also metacognition techniques that produce results. These tools are in my bag of what I call my debuggers for removing automatic thoughts that produce negative emotions, or what ancient Hindus call a "vasana." A vasana can also be a memory of a good feeling, which drives behavior for more, which is a problem for gamblers for example. If you yearn for adventure in South America or like the idea of doing mind altering drugs, by all means do it, but just know it is not the only way. Ram Dass called psychedelics training wheels and said you don't need them after awhile. The point is to break out of the box, but once out, you don't need to keep doing it.
