of his friend, Wally Hope. Crass had its roots in Dial House, which was established in 1967 as a commune. Some punks were often critical of Crass for their involvement in the hippie movement. Like Crass, Jello Biafra was influenced by the hippie movement, and cited the yippies as a key influence on his political activism and thinking, though he also wrote songs critical of hippies. Drugs Following in the footsteps of the Beats, many hippies used cannabis (marijuana), considering it pleasurable and benign. They used drugs such as marijuana, LSD, magic mushrooms, and mescaline (peyote) to gain spiritual awakening. On the East Coast of the United States, Harvard University professors Timothy Leary, Ralph Metzner and Richard Alpert (Ram Dass) advocated psychotropic drugs for psychotherapy, self-exploration, religious and spiritual use. Regarding LSD, Leary said, "Expand your consciousness and find ecstasy and revelation within." On the West Coast of the United States, Ken Kesey was an important figure in promoting the recreational use of psychotropic drugs, especially LSD, also known as "acid." By holding what he called "Acid Tests", and touring the country with his band of Merry Pranksters, Kesey became a magnet for media attention that drew many young people to the fledgling movement. The Grateful Dead (originally billed as "The Warlocks") played some of their first shows at the Acid Tests, often as high on LSD as their audiences. Kesey and the Pranksters had a "vision of turning on the world." Harder drugs, such as cocaine, amphetamines and heroin, were also sometimes used in hippie settings; however, these drugs were often disdained, even among those who used them, because they were recognized as harmful and addictive. Legacy Culture The legacy of the hippie movement continues to permeate Western society. In general, unmarried couples of all ages feel free to travel and live together without societal disapproval. Frankness regarding sexual matters has become more common, and the rights of homosexual, bisexual and transgender people, as well as people who choose not to categorize themselves at all, have expanded. Religious and cultural diversity has gained greater acceptance. Co-operative business enterprises and creative community living arrangements are more accepted than before. Some of the little hippie health food stores of the 1960s and 1970s are now large-scale, profitable businesses, due to greater interest in natural foods, herbal remedies, vitamins and other nutritional supplements. It has been suggested that 1960s and 1970s counterculture
