"The LSD market took an earlier blow in 1995, when Grateful Dead frontman Jerry Garcia died and the band stopped touring. For 30 years, Dead tours were essential in keeping many LSD users and dealers connected, a correlation confirmed by the DEA in a divisional field assessment from the mid-'90s. The spring following Garcia's death (the season the MTF surveys are administered), annual LSD use among 12th-graders peaked at 8.8 percent and began their slide. Phish picked up part of the Dead's fan base—and presumably vestiges of the LSD delivery system. At the end of 2000, Phish stopped touring as well, and perhaps not coincidentally, the MTF numbers for LSD began to plummet."
