On October 6, 1966, the state of California declared LSD a controlled substance, which made the drug illegal. In response to the criminalization of psychedelics, San Francisco hippies staged a gathering in the Golden Gate Park panhandle, called the Love Pageant Rally, attracting an estimated 700–800 people. As explained by Allan Cohen, co-founder of the "San Francisco Oracle", the purpose of the rally was twofold: to draw attention to the fact that LSD had just been made illegal—and to demonstrate that people who used LSD were not criminals, nor were they mentally ill. The Grateful Dead played, and some sources claim that LSD was consumed at the rally. According to Cohen, those who took LSD "were not guilty of using illegal substances...We were celebrating transcendental consciousness, the beauty of the universe, the beauty of being."
