Yes. Thanks very much.
These drugs, both marijuana and other forms of recreational drugs, are being used, and I think they're being used for their effects on the nervous system. They have direct effects, of course, whether they be relaxants or stimulants. They have various dissociative qualities, which you mentioned, such as the suppression of memory and distress in the immediate short term.
My thought here is actually the idea of “meditate versus medicate”. Some similar effects can be achieved through mental practices. It's not so immediate as far as the effects of the drug go, but with time these forms of mental training that I was referring to—the meditations, the biofeedback, and particularly the neurofeedback—can achieve some of those benefits of relaxing the nervous system, improving concentration, and improving mental control.
