First synthesized by Albert Hofmann on November 16, 1938, LSD went on to become a staple of the psychedelic world and the centerpiece of the 1960s counterculture. On April 19, 1943, Hofmann returned to investigate LSD further and ingested 250 micrograms of LSD. Hofmann believed this dose to have a minuscule, threshold effect. He rode his bicycle home and later wrote that, "... little by little I could begin to enjoy the unprecedented colors and plays of shapes that persisted behind my closed eyes. Kaleidoscopic, fantastic images surged in on me, alternating, variegated, opening and then closing themselves in circles and spirals, exploding in colored fountains, rearranging and hybridizing themselves in constant flux ..." This day in history later became known as Bicycle Day and is celebrated by LSD enthusiasts as the world's first LSD trip.

User may feel "out of it" and generally off the day after, esp. with larger doses. Residual euphoria and a "ready to take on the world" feeling may persist. No bodily harm from recreational doses of LSD, though mental effects from long term chronic use can be negative in some people.
Avoid driving and operating heavy machinery.
At least three days for full effect due to rapid tolerance build, though it's generally advised to wait longer between trips. Ingesting LSD no more than once a month is advised due to the adverse psychological effects of chronic use. The addiction potential of LSD is nonexistant, save rare cases in which a person becomes psychologically addicted.
