I actually enjoy the music without taking any drugs, but my default state is quite hyperactive. The loud bass, the energy of the crowd, the people feeling comfortable and enjoying themselves makes me feel energized and allows me to relax and dance in an enjoyable anonymity. To your point, when I was photographing concerts (&clubs/raves) regularly I did quickly realize I'm an outlier, and most people and performers were in fact consuming copious amounts of drugs... The least enjoyable events were those where everybody was escaping something - consuming drugs, over-drinking alcohol, destroying property – while the best events had a tight-knit community, proper security, pop-up drug labs ( https://drugfoundation.org.nz/articles/checkit-out ) and most importantly a mature audience.
