LSD

D-lysergic acid diethylamide, commonly called acid, LSD, or LSD-25, is a powerful semisynthetic psychedelic drug. A typical dose of LSD is only 100 to 150 micrograms, a tiny amount roughly equal to one-tenth the weight of a grain of sand. Threshold effects can be felt with as little as 20 micrograms. LSD causes a powerful intensification and alteration of senses, feelings, memories, and self-awareness for 6 to 14 hours. In addition, LSD usually produces visual effects such as moving geometric patterns, "trails" behind moving objects, and brilliant colors. LSD usually does not produce hallucinations in the strict sense, but instead illusions and vivid daydream-like fantasies. At higher concentrations it can cause synaesthesia.

"Today a young man on acid realized that all matter is merely energy condensed to a slow vibration, that we are all one consciousness experiencing itself subjectively, there is no such thing as death, life is only a dream, and we are the imagination of ourselves. Here's Tom with the weather." (Bill Hicks)
