At least around here (SF Peninsula/Silicon Valley), "pot" isn't a derogatory term at all. It seems to be what most everyone calls it, users and non-users alike.

Except for the kids. They call it "weed". Which is a bit confusing because "weed" used to mean the cheap stuff and "pot" the good stuff.

A few people called it "dope" 25-30 years ago, but that didn't last. Before that it was "grass", but that really was the bad cheap stuff, ten dollars a lid (an ounce of leaves in a baggie with the flap sealed by spit) from Mexico.

The dispensaries and producers seem to prefer "cannabis" - there's Buddy's Cannabis for example - or "medical marijuana", but never just "marijuana".

In fact, the dispensaries never call it "pot" either. It's "medicine" or "flowers", or just referred to by the name of the specific strain.
