psychedelic drugs

In the beginning stages of onset, psychedelic drugs, such as LSD, is likely to cause a sort of undefineably feeling similar to anticipation or anxiety. There is often a slight feeling of energy in the body, an extra twinkle to lights, or the feeling that things are somehow different than usual. As the effects become stronger, a wide variety of perceptual changes may occur; non-specific mental and physical stimulation, pupil dilation, closed and open eye patterning and visuals, changed thought patterns, feelings of insight, confusion, or paranoia, and quickly changing emotions (happiness, fear, giddiness, anxiety, anger, joy, irritation). Making them the so-called mind-expanding drugs. As the 1960s progressed, San Francisco's flower children, also called hippies adopted new styles of dress, experimented with psychedelic drugs, lived communally and developed a vibrant music scene Grateful Dead. When people returned home from "The Summer of Love" these styles and behaviors spread quickly from San Francisco and Berkeley to many U.S. and Canadian cities and European capitals.
