He says the first time he tried marijuana, it induced fascinating perceptual distortion. He was looking at his hand, and it appeared to be retreating from him, yet getting larger and larger.

“I was fascinated that one could have such perceptual changes, and also that they went with a certain feeling of significance, an almost numinous feeling.
