Berkeley flashbacks at Annapurna! This headshop has been open for fifty years and they have probably sold more incense than any other headshop ever. It's quite an accomplishment. The owner Alfred is super friendly. I used to buy Spiritual Sky, satya nag champa, and djarums here when I was a younger person living in the bay area.
It's interesting to think about how incense and intoxicants have a long history of association. There is a shadow side of incense that merits further investigation. This shadow side of incense involves lots of shady stuff like counterfeiting, smuggling, as well as connections with esoteric topics like magick and altered states of consciousness.
