Did Dock Ellis Pitch a No-No on LSD?

From Big League Stew. This video was made based on an interview Ellis did. According to Dock, the no-hitter he pitched against the San Diego Padres, on June 12, 1970, was done while he was "High as a Georgia pine." Is it even possible to pitch a no-hitter while on acid?

Ellis said, "I can only remember bits and pieces of the game. I was psyched. I had a feeling of euphoria. I was zeroed in on the (catcher's) glove, but I didn't hit the glove too much. I remember hitting a couple of batters and the bases were loaded two or three times. The ball was small sometimes, the ball was large sometimes, sometimes I saw the catcher, sometimes I didn't. Sometimes I tried to stare the hitter down and throw while I was looking at him. I chewed my gum until it turned to powder. I started having a crazy idea in the fourth inning that Richard Nixon was the home plate umpire, and once I thought I was pitching a baseball to Jimi Hendrix, who to me was holding a guitar and swinging it over the plate. They say I had about three to four fielding chances. I remember diving out of the way of a ball I thought was a line drive. I jumped, but the ball wasn't hit hard and never reached me."
