This interesting result was compounded by the observation that when a dolphin on LSD is joined in the pool by another human or dolphin, its duty cycle was sustained at an average of 70 percent for up to three full hours. For the sake of comparison, in control trials where the dolphin was not on LSD, Lilly found that that the duty cycle was closer to ten percent.

In other words, when a dolphin was injected with LSD, it just couldn’t stop “talking.”
