"Drugs are like a telephone , when you get the message hang up"
When he returned to the United States, he began to dabble in psychedelic drug experiences, initially with mescaline given to him by Dr. Oscar Janiger. He tried LSD several times with various research teams led by Drs. Keith Ditman, Sterling Bunnell, and Michael Agron. He also tried marijuana and concluded that it was a useful and interesting psychoactive drug that gave the impression of time slowing down. Watts’ books of the ’60s reveal the influence of these chemical adventures on his outlook. He would later comment about psychedelic drug use, "When you get the message, hang up the phone."
Alan's thoughts continued
"Psychedelic experience is only a glimpse of genuine mystical insight, but a glimpse which can be matured and deepened by the various ways of meditation in which drugs are no longer necessary or useful. If you get the message, hang up the phone. For psychedelic drugs are simply instruments, like microscopes, telescopes, and telephones. The biologist does not sit with eye permanently glued to the microscope, he goes away and works on what he has seen..."-- Alan Watts, (Joyous Cosmology Prologue, 2nd ed. 1970)."
