Rita simply turns her head away at 9S's recommendation. Nope. Not today, not sometime. Rita's greatest asset is her mind. She can't imagine ever wanting to impair it intentionally.

Still, 9S has a weirdly positive view of drugs. Is that just from the information he has about how humans used them, or...?

"Have you done anything like this before, 9S?" she asks. "I mean... would drugs even work for an android?" Sure, he can eat and drink, but his body must not process those things quite like a human's does. This is as much an experiment for him as it is for Cole... isn't it?
