I've noticed that the word pot has a bit of a negative connotation to it, If you say it around the wrong kind of people, they'll think your a narc.

But then again, it's yet another word for marijuana.
Glad to see some good info on the subject though, I've always found it interesting to see how words and terminology associated with drug culture in general change and evolve over time. Who knows what people will be calling marijuana in the next 10 to 20 years, maybe if legalization starts taking place people will just start referring to marijuana by whatever brand name they like to buy...
