No, I completely understand. I, too, suffer from the fact I don't follow along with most of the cannabis culture/community.

They always talk about how 'fucked up' or high they are, they can't seem to understand the concept of not smoking when someone offers you, and they think there are only 3 things you need to work towards: Booze, Pot, and Sex.

I can go on for hours, don't feel too bad. The way I've always found to 'train' them out of doing such things is to be very sarcastic, tongue-in-cheek, but point out what they're doing... so next time they say "Dude I'm so fucked up" say something akin to "No, you think? Considering we just smoked x amount of weed." OK, that line sucks but you get the gist of it I hope.
