“After experiencing drastic changes in my environment, I looked for other experiences that might profoundly affect my perception of the self. So I devised another experiment where everyday I took a different drug and drew myself under the influence. Within weeks I became lethargic and suffered mild brain damage. I am still conducting this experiment but over greater lapses of time. I only take drugs that are given to me.”
I don't see some on there, but it says it's still be conducted.
