What is a common effect of LSD (Lysergic Acid Diethylamide)?

The correct response highlights that one of the common effects of LSD is the distortion of time. Users frequently report experiencing time as moving either much faster or slower than it actually is. This alteration in the perception of time is a hallmark of the psychedelic experience associated with LSD, which significantly affects sensory perception and cognitive function.

While other effects are associated with LSD, such as heightened senses or alterations in mood, the specific perception of time is notably prominent among users. This aspect can lead to profound experiences during an LSD trip, impacting one's ability to accurately judge the passage of time. Enhanced visual experiences, significant changes in thought processes, and some loss of the usual boundaries of self are also common, but the phenomenon of time distortion is particularly characteristic of LSD's effects.
