Does anyone know a source where I can read about the origins of the common marijuana slang terms, ie. the "etymology" of the terms? For example, there is a site called "rapdict.org," that contains a basic glossary where you can look up a word or phrase from a rap song lyrics you've heard, and it tells you what it means, and how the useage of that word or phrase evolved. Is there anything like that for marijuana use? If not, maybe someone just knows the answers off-hand? I'm mainly curious about the following terms, as in how they came to be called what they are called:

*joint
*bowl
*bong
*roachclip
*hit
*toke
*pot
*dope
