For the senior citizens viewing this they might relate the term "AngelDust" with the dissociative PCP, let me assure them though, it hasn't been called AngelDust since the 70s. You'd be much more likely to hear it referred to as "wet" or "sherm". IF you went to the ghetto and tried t buy Angel Dust they'd think you were a cop. It's like calling weed "dope". Just a little disambiguation from a drug name etymologist :)
