Sam: Get outta here, Dewey!
Dewey:What are y'all doin' in here?
Sam: We're smoking reefer and you don't want no part of this shit.
Dewey Cox: You're smoking *reefers*?
Sam: Yeah, 'course we are; can't you smell it?
Dewey Cox: No, Sam. I can't.
Girl Groupie: Come on, Dewey! Join the party!
[takes a hit off a joint]
Sam: No, Dewey, you don't want this. Get outta here!
Dewey Cox: You know what, I don't want no hangover. I can't get no hangover.
Sam: It doesn't give you a hangover!
Dewey Cox: Wha-I get addicted to it or something?
Sam: It's not habit-forming!
Dewey Cox: Oh, okay... well, I don't know... I don't want to overdose on it.
Sam: You can't OD on it!
Dewey Cox: It's not gonna make me wanna have sex, is it?
Sam: It makes sex even better!
Dewey Cox: Sounds kind of expensive.
Sam: It's the cheapest drug there is.
Dewey Cox: Hmm.
Sam: You don't want it!
Dewey Cox: I think I kinda want it.
Sam: Okay, but just this once. Come on in.
