Personally I either call it: herb or fruit from the dolittle tree I also like to say, 'I'm on the pot' for some reason it cracks me up.
gear, chuff, ganj, weed, pot, i have a codename with some friends 'fanta'. chop. but i use weed the most. or if im tlaking to someone who is not accepting of it, or dissaproving, ill usualyl call it cannabis or marijuana. saying weed to thsoe sorta poeple is jsut like putting yourself down, making them think 'hey if a stoner thinks its a weed then who says its not?'. but yeh
i call it just about any slang name you can think of.... greenery, and the good green are another 2 i use
"the medicine" That's how George Washington referred to it (at least, in one document). It has a nice ring, don't you think?
