Are Phish fans huge stoners?
I'm not going to lie: a lot of Phish fans indulge in weed or MDMA during shows. If you go to a Phish concert, someone will shove a joint in your face and offer you a puff. Multiple times. Some people indulge too much and end up at the first-aid tent. In the parking lot, some jokers end up doing whip-its. One time, a putz ran in front of my car and nearly got killed. At a New Year's concert a blitzed-out girl covered in flashing lights and wearing a unicorn horn kept wanting to hug my wife. Sure, why not? (Later, well past midnight, she asked when the countdown would start. She was standing right there when thousands of balloons fell inside Madison Square Garden.)
Despite all the open drug use, whacked-out lyrics ("Split Open and Melt"), and occasional shouting of "Kush! Kush!", Trey Anastasio has been 100% clean and sober since a DWI arrest in 2006. The other members of the group are, according to lore, "pretty much sober," these days, too, either for their own well-being or to avoid enabling their frontman. Years ago, their backstage antics were in tune with the crowd, but now, seconds after the final encore, each member of the group gets on his individual bus that whisks them away from the venue, a temptation-avoidance strategy borrowed from Neil Young.
Still, a lot of people enjoy the show with nothing more than a can of 7UP. During the summer shows, many people take their kids and let them run around on the back of the lawn. Everyone is groovin' and having a good time.
